Early exposure to dogs lessens the risk of schizophrenia

An important study conducted by Robert Yolken, M.D. the chair of the Stanley Division of Pediatric Neurovirology at the Johns Hopkins Children’s Center showed that early exposure to dogs may lessen the risk of children developing schizophrenia and bipolar disorder. The study also explored if early exposure to cats had the same affect. It seems that it has not been proven if cats produce the same results.

It is not hard to understand how this is possible when you realize, as the article explains, that serious psychiatric disorders are associated with changes in the immune system. Changes result from exposure to different environmental conditions (not just pets). In the case of pet cats and dogs, they can affect the immune system through allergic responses, bacteria related to pets, contact with animal bacteria and viruses, the microorganisms in the home environment as well as the reduction of stress which changes the brain chemistry.

While this study has given us insight to another benefit of raising a child during his first 13 years with a dog (and possibly a cat), the study points out that more research is needed. It is my hope that researchers will eventually be able to pinpoint the exact cause of this benefit and develop a way to use it to help many people.

Asthma and Pets

In a new study conducted by the Nationwide Children’s Hospital, if parents and children follow the NAEPP (EPR-3) guidelines for asthma control in children, pets and secondhand smoke does not increase their symptoms. This is important to those people who love pets because it means that a family does not have to get rid of a pet if a family member develops asthma.

This is also important because if a child suffers from asthma, a pet can be a big comfort to them if the asthma interferes with other activities.

However, it is important to work with your health care provider and follow the NAEPP (EPR-3) guidelines. The study shows that asthma treatment is more important than exposure to elements in the environment.

Hypoallergenic pets and children

In the past, researchers have determined that children who have a pet dog or cat, or those who live in rural areas around livestock, have less of a chance to develop asthma and allergies to pets.

A recent study conducted by Tove Fall, Senior Lecturer at the Department of Medical Sciences — Molecular Epidemiology at Uppsala University, who led the study with Professor Catarina Almqvist Malmros at Karolinska Institutet showed some interesting results.

They determined that the sex of the dog was a factor in reducing an allergic reaction in children. It seems that children who lived with female dogs and more than one dog in the home had less allergies.

They also found that children who lived with the breeds and mixes of dogs that are supposed to be ‘hypoallergenic’ actually had a higher percent of allergies. That the hypoallergenic dogs were not better for children.

A child will benefit the most from having a pet in the home if they are raised the first year of their life with the pet.

The fact that the hypoallergenic breeds are not really hypoallergenic is especially important information for those parents who may be considering a dog for their child who has allergies.

Many people are duped into paying high prices for supposed hypoallergenic designer mixes and breeds that are labeled as hypoallergenic. No matter what the mixed breed is supposedly mixed with, it is still a mixed breed with no proof that it is what the breeder claims to be. I have personally seen many cases where the supposed mix of Goldendoodle or Labradoodle grow up to have the characteristics of a completely different breed. In some cases DNA tests showed the dog was not what it was claimed to be.

Although more research needs to be done, it appears that getting a female dog of the breed that you want is the best course of action. If you plan to start a family, get the dog first. Have the dog trained by the time you start the family. It will make the situation much easier and benefit the children that join your family.

Asthma – Children – Pets

A recent study by the Nationwide Children’s Hospital to determine if second-hand smoke and living with a pet had a role in controlling severe asthma in children, found interesting results.

In the past if a child had asthma and the family had a pet, the family was often encouraged to get rid of the pet. This is a heartbreaking situation. If the child is old enough to realize that it is because of them that the pet was re-homed, it could cause the child to feel as though they are the blame. This feeling of guilt on top of the grief of losing the pet can be very difficult for a child to deal with.

However, the most recent study has shown that if the child’s asthma is managed per NAEPP (EPR-3) guidelines that second-hand smoke and pets do not cause the asthma to get worse or prevent it from improving.

This is very good news for families where a child, or even a family member, suffers from asthma. It also means that a child who has asthma does not have to be denied the joy of owning a pet.

Dog ownership lessens risk of heart disease

In a unique Swedish study, researchers found that people who owned dogs had a lower mortality rate then those who did not. They also found that people who lived alone and owned a dog had less cardiovascular diseases then people who lived alone who did not own a dog.

The researchers studied 3.4 million people between the ages of 40 and 80 making this a comprehensive comparison. What the study did not show was why there was a difference between dog ownership and non-dog ownership.

One possibility considered was that people who own dogs are more active because they walk their dogs. There was also no indication as to whether or not there were other factors such as the type of people who own dogs vs those who do not.

However, the bottom line is that dog ownership, again, has proven to benefit the health of their owners. It would be interesting to study how growing up with a dog or pet affects the health of children as adults if they continue to own a pet vs those who get a dog or pet later in life. We know that children who own pets are less prone to developing allergies. It would be interesting to know what other physical and mental benefits pet ownership has on children.

Pets benefit babies by reducing the rate of allergies and obesity

Previous studies have shown that children who grow up around animals, including livestock, have a reduced rate of allergies. Now another study suggests that having a pet in the home, especially dogs help infants invitro as well as after they are born, have less instances of allergies and obesity.

Anita Kozyrskyj, a U of A pediatric epidemiologist who is one of the world’s leading researchers on gut microbes (bacteria that live in the digestive tracts of humans and animals) and her team have studied the relationship between less instances of allergies (especially asthma)  in children who live with pets, for over two decades.

Her Team has shown that a mother’s exposure to pets while pregnant, and the child up to three months after the birth, increases two bacteria, Ruminococcus and Oscillospira which are responsible for the reduction of allergies and obesity. These bacteria were almost doubled in the child’s body when pets, mostly dogs, were present before and after birth.

Kozyrskyj’s study also showed that having pets in the house during pregnancy reduced the transmission of vaginal GBS a group B strep during birth. GBS can cause pneumonia in newborns.

How wonderful are our pets!
