Pet ownership is more than just a source of joy—it’s a gateway to better health and a more fulfilling life. From reducing stress levels to promoting physical activity, the bond between humans and their pets profoundly impacts overall well-being. This article explores how pets contribute to a healthier, happier lifestyle, showcasing their unique role in enriching our lives.

The Mutual Benefits of Pet Interaction

Spending time with pets like dogs and cats can be a delightful way to unwind and reduce stress. Engaging in regular playtime and maintaining a consistent routine with your furry friend can help lower cortisol levels, a key stress hormone. This benefits your health and positively impacts your pet’s well-being, as your stress can affect them, too. Consider working from home occasionally or arranging for a pet sitter if your pet shows signs of stress. These steps can create a more harmonious environment, enhancing your and your pet’s health and happiness.

Boosting Your Immune System with Pet Companionship

Owning a pet can be a delightful way to boost your immune system. Sharing your home with a pet, especially a dog, exposes you to various microbes that can strengthen your body’s defenses. Research indicates that children raised with pets often develop a more diverse gut microbiome, which is associated with a lower risk of asthma and allergies. This aligns with the hygiene hypothesis, suggesting that early exposure to microbes can help the immune system manage allergens more effectively.

The Mental Health Benefits of Pet Care Routines

Establishing a routine through feeding, grooming, and exercising your pet provides structure and instills a sense of purpose and accomplishment. This routine can be particularly beneficial for those facing mental health challenges, as it encourages regular physical activity and fosters a stable environment. The bond you form with your pet through non-verbal communication can uplift your mood and alleviate anxiety. Studies suggest that over 60% of dog owners achieve recommended exercise levels, highlighting the physical benefits of pet ownership.

How Therapy Animals Help with Mental Health

Therapy animals have increasingly become a vital component of mental health care, offering comfort and support to individuals facing challenges such as PTSD and autism. Their calming presence can significantly enhance social skills, reduce anxiety, and promote emotional stability across diverse groups. For example, equine-assisted therapy involves interactions with horses and is particularly effective in building trust and facilitating emotional healing. Additionally, service dogs are trained to address specific needs, such as providing mobility support or detecting health issues like low blood sugar, enhancing independence and quality of life.

The Health Benefits of Pet Ownership

Delving into the science of the human-animal bond reveals its significant impact on health and well-being. Engaging with pets can lower blood pressure and ease anxiety, mainly due to releasing hormones like oxytocin and dopamine, which foster happiness and relaxation. The companionship of a pet can alleviate loneliness and depression, enhancing your overall quality of life. Understanding these dynamics lets you appreciate how pets contribute to a healthier, more fulfilling life.

New research about overeating

/ susanbulanda / 1 Comment

UCLA psychologists have discovered a circuit in the brain of mice that makes them crave food and seek it out, even when they are not hungry. What is interesting about this discovery is that when the group of cells is stimulated, the mice seek fatty and pleasurable foods such as chocolate instead of healthier foods such as carrots.

The area of the brain where the cells are located is called the periaqueductal gray which is in the brainstem. When these cells are stimulated, the mice are so driven to eat that they will endure foot shocks to get to the food. The opposite occurs when the researchers inject a virus that produces a protein that reduces the cells activity even hungry mice foraged less.

“Like mice, humans also possess vgat PAG cells in the brainstem. It could be that if this circuit is overactive in a person, they might feel more rewarded by eating or crave food when not hungry. Conversely, if this circuit is not active enough, they could have less pleasure associated with eating, potentially contributing to anorexia. If found in humans, the food-seeking circuit could become the treatment target for some kinds of eating disorders.”

Sue’s Note: If mice have this cluster of cells, it stands to reason that other animals have it as well. Could this be why some of our pets overeat and some have low appetites?

Dogs understand words from a soundboard

/ susanbulanda / Leave a comment

A new study investigated whether dogs understand the words on a soundboard or if they were responding to cues from their owners. The study was conducted by researchers at the University of California San Diego as well as other institutions and have proven that dogs who are trained with soundboard buttons can comprehend specific words and will perform contextually appropriate responses. The study was led by Federico Rossano who is an associate professor in the Department of Cognitive Science at UC San Diego and is head of the comparative Cognition Lab. This study was the first empirical study from the world’s largest longitudinal or panel study of button-trained pets.

The way the study was conducted removed bias, owner cues, and showed that the dogs truly did understand the words on the sound board. One of the more important findings is that it shows the complexities of dog cognition and communication.

Sue’s Note: Since I first started training dogs and working as a behaviorist, we have come a long way in understanding how intelligent dogs (and other animals) are. One of the key lessons that we as pet owners must keep in mind, is that dogs are much smarter than previously thought and understand much more than most people give them credit for. This is important to keep in mind when training any animal. What you do and how you do it is critical in building your relationship with your dog or other pet and having them understand what you are teaching them or want them to do. This is why it is very important to use the same word for a specific command. For example, do not use the word DOWN to tell your dog to get off you or furniture and then say the same word to tell your dog to lie down.

A new cancer treatment for dogs and cats

/ susanbulanda / Leave a comment

Researchers have found a new way to extend the life of terminally ill dogs who have cancer. This new form of chemoimmunotherapy repurposes stem cells that uses a non-viral gene delivery treatment instead of the usual virus treatment. The new method is safe has had great results.

The researchers treated 65 dogs and two cats who had either adenoma, lung metastasis or sarcoma. After three to eight weeks of treatment, 55 showed signs of positive response. Of that 14 had a full recovery. Two animals remained cancer free for at least 30 months and 46 enjoyed a good quality of life for 32 months. None of the animals treated had significant side effects.

The research team are conducting further studies and plan to research the possibility of using this treatment on humans.

Stress causes overeating in pets

/ susanbulanda / Leave a comment

Researcher Sora Shin, an assistant professor at the Fralin Biomedical Research Institute at Virginia Tech has discovered a molecule that triggers the need to eat high fat foods in mice 24 hours after being exposed stress in the form of the scent of cats.

This molecule is found in the hypothalamus section of the brain which is the part of the brain that is connected to changes in the brain that lead to emotional overeating.

 The same molecule is found in people as well as animals. This discovery may lead to treatment methods that can help people who react to the emotionally driven need to overeat, even when they are not hungry.

Sue’s Note: There are many animals, particularly dogs and cats that tend to overeat which result in them becoming obese. Pet owners who have pets that have this problem should consider stress as a factor that causes their pets to overeat. First be sure that the family or friends are not over feeding the pets. If this is not the case the pet owner should evaluate the possibility that stress may be a cause. Since the study showed that the effects of stress can cause overeating 24 hours later, the pet owner should consider events that happened in the last 24 hours. An example would be someone or something that passes the pet’s home when the owner is not home that causes high stress in the pet. In situations where stress is a factor, reducing the amount of food that the pet has access to may cause a greater amount of stress. In this case over the counter calming remedies may help the pet. If not a visit to your veterinarian would be in order explaining to the veterinarian that you suspect stress is a cause of the overeating.

Unlock the Healing Power of Animal Companionship in Overcoming Addiction

/ susanbulanda / Leave a comment

by guest blogger Cindy Aldridge

Embarking on the path to overcoming addiction, you might discover solace and support in unexpected places. Among these, the companionship of pets stands out as a source of unconditional love and understanding. These furry friends offer companionship and become critical pillars in the journey toward sobriety, providing a unique form of support that nurtures emotional and physical well-being. Susan Bulanda shares more:

Providing Companionship and Sense of Purpose

In the throes of addiction recovery, the presence of a pet can imbue your life with a newfound sense of purpose and belonging. The unconditional love and unwavering companionship pets offer can fill the void of loneliness, giving you a reason to push forward. 

Their dependence on you for care and affection instills a routine and responsibility that can be incredibly grounding. This bond is crucial to the recovery process, offering a comforting presence that reassures and motivates you to continue healing.

Navigating Through Inpatient Treatment

When grappling with the complexities of addiction recovery, acknowledging the potential for relapse becomes pivotal. In such instances, opting for inpatient treatment emerges as a decisive choice, offering a structured and supportive setting for individuals navigating the trials of recovery. While concerns about the expense of rehabilitation may arise, it’s reassuring that numerous treatment centers readily accept health insurance from major providers. 

Mitigating financial worries requires proactive engagement with insurance companies to ascertain the extent of coverage. Selecting the right inpatient facility involves a multifaceted approach; start with this list of best rehab centers in the US. Take into account accommodations, accreditations, treatment approaches, location, and the testimonials of former patients. 

In parallel to choosing a rehabilitation center, it’s crucial to ensure your pet’s well-being by arranging temporary housing. Research local pet boarding facilities or consider pet-sitting services that can offer personalized care in your absence. Engaging with a trusted provider early on will give you peace of mind, knowing your furry friend is in safe hands while you focus on your recovery.

Alleviating Stress Through Pet Interaction

Petting or simply being near an animal has been shown to reduce stress and significantly lower cortisol levels. This interaction promotes a sense of calm and well-being, which is particularly beneficial during the unpredictability of addiction recovery. 

The routine of caring for a pet provides a distraction from stressors and a way to channel energy positively. This natural form of stress relief can make a significant difference in managing recovery’s emotional ups and downs, offering a peaceful respite in moments of turmoil.

Overcoming Loneliness with the Company of Pets

The companionship of a pet combats the loneliness and isolation felt during addiction recovery, offering comfort and a sense of security that diminishes the risk of relapse. Their simple, unwavering support lightens the complexities in human relationships, making the path to sobriety feel less intimidating. This bond is a constant reminder that you are never truly alone in your journey toward healing.

Fostering Emotional Healing Through Pet Bonding

Pets provide a unique outlet for emotional expression, offering a safe space to express feelings without fear of judgment or reprisal. This aspect of pet ownership can be particularly therapeutic during addiction recovery, where emotional vulnerability is often a key part of the healing process. Caring for an animal can help redirect focus from personal struggles to the well-being of another, facilitating a form of emotional healing that is both subtle and profound.

Promoting Physical Health and Activity

Engaging in physical activities with a pet, such as walking or playing, strengthens your bond and promotes your own physical health. This routine encourages regular exercise, which is an essential component of a healthy recovery process. The physical benefits of activity and the emotional support of pet companionship contribute to a holistic approach to overcoming addiction, enhancing mental and physical resilience.

Encouraging Mindfulness and Presence

Caring for a pet requires mindfulness and presence which can be incredibly beneficial during addiction recovery. This responsibility encourages you to live in the moment, focusing on your pet’s needs rather than dwelling on past mistakes or future anxieties. This mindfulness practice fosters a sense of peace and connection, grounding you in the present and supporting a more mindful, purposeful approach to recovery.

In the challenging journey of overcoming addiction, the companionship of pets offers a powerful source of healing and support. Beyond mere companionship, they provide love, purpose, and a unique form of unconditional support that can significantly impact your recovery process. As you navigate the path to sobriety, consider embracing the therapeutic power of pets to find strength, resilience, and comfort in their presence.

Rats have the ability to imagine

/ susanbulanda / Leave a comment

Researchers at the Howard Hughes Medical Institute Janelia Research Campus have discovered that rats have the ability to imagine. There findings indicate that just like people, animals can think about places and objects that they cannot see.

To determine this, they used a Brain Machine Interface and saw that rats showed specific neural activity patterns in the hippocampus area of their brain which is related to spatial memory. The researchers have determined that this function is necessary for an animal to remember past events and imagining future scenarios even if the animal is at a different location.  

Sue’ Note: While this research is important because it gives scientific proof that animals can remember the past and think of the future, it is obvious to me because if animals cannot do this, those in the wild would not survive. Our domestic animals would not be able to learn the things we teach them. An example that many of us have observed is the dog who knows what time a person is coming home and waits at the door, long before he could hear, smell or see the person coming. This is evident when the person is late and the dog at waiting at the normal time and illustrates the dog’s ability to anticipate the future. A famous example of this is Hachikō, an Akita who lived in Japan from 1923 to 1935 and went every day to the train station to wait for his master after his master died.

Scent and Memory

/ susanbulanda / 1 Comment

According to a study done by researchers at the UCI Center for the Neurobiology of Learning & Memory at the University of California, adults who were ages 60 – 85 who were suffering from some sort of mental impairment partook of the scent therapy test.  

The subjects of the study were given a diffuser and seven cartridges, each with a natural oil. The subjects used the diffuser each night when going to bed. The diffuser ran for two hours. The results showed that the group with the full-strength diffusers improved their cognitive skills by 226%.

Imagining showed that there was better integrity in the brain pathway called the left uncinate fasciculus, which connects the medial temporal lobe to the decision-making prefrontal cortex.

In addition to having better memory, the subjects said that they slept better, more soundly.

Sue’s Comments:  We know that essential oils have numerous benefits when smelled. For example, lavender is known for its calming properties. What this study brings to mind for me is the possible connection with scent work in dogs. There are many accounts of animals, dogs, elephants, and other animals, who recognize a person that they have not seen in years. Scent is one of the keys for this, indicating that there may be a connection similar to the findings in this study. Previous studies have shown that in dogs, scent is linked to sight, they are not separate in the dog’s brain. I would love to see further studies that involve this finding and how it might apply to animals. Would it be possible to help elderly animals in the same way. Dogs and other animals suffer from dementia the same as people.

Gene therapy to prevent pregnancy in dogs and cats

/ susanbulanda / Leave a comment

A Research team led by David Pépin, PhD, Associate Director of the Pediatric Surgical Research Laboratories at Massachusetts General Hospital, and an Associate Professor at Harvard Medical School has developed a gene therapy as an alternate to spaying and neutering animals. They are hopeful that this method will eventually be available to be able to control outdoor pet populations.

While this discovery is promising, the researchers have yet to develop the infrastructure to treat thousands of unowned feral cats. This will also give pet owners an alternative to traditional spay and neuter programs to prevent pregnancy in their pets.

What is interesting is this gene therapy was first used in people. Typically discoveries in animals help humans, in this case it is the reverse.

Those amazing whiskers

/ susanbulanda / Leave a comment

A study at Northwestern University has shown that rats determine the direction of the wind with their whiskers. Since many other animals such as dogs, foxes, coyotes and cats also have whiskers that are similar to those of a rat, is it possible that they also use their whiskers to determine the direction of the wind?

All wild animals also have to be aware of the direction of the wind to either find food or avoid being detected by predators. Therefore, the ability to determine the direction of the wind or even a slight breeze is a life and death skill. It seems reasonable that that they would use their whiskers as well as the movement of their fur to detect the direction of air movement.

Sue’s Note: As a person who has trained many working dogs, I have seen dogs learn how to use the direction of the wind to find scent. It is quite an amazing thing to watch, and another example of how intelligent animals are.
