Puppies and adult dogs will often swallow a foreign object that can potentially harm them. If they ingest an object that is sharp, and they seem normal and are not gagging, or choking, immediately give them Metamucil or another psyllium fiber product and then call your veterinarian. I keep unflavored psyllium fiber on hand so that if necessary, I can add broth to it so the dog will eat/drink it. If you don’t have psyllium fiber on hand the old-time remedy was to give the dog bread and milk or bread and water. The purpose of doing this is to form bulk or a coating around the object to prevent it from injuring the dog until a veterinarian can evaluate the situation and treat the dog. It is a first aid measure, not a cure.

Dogs should not be given any product that can be chewed into small undigestible pieces. Such items would be bones, both real and fake, plastic toys, balls, sticks, some of the teeth cleaning chews/products, rawhide, pig ears, and cow hooves. If you are in doubt as to whether or not a product is safe for your dog to eat, put it in a bowl of water. If it does not break down and dissolve in five to ten minutes it is most likely not safe for your dog to ingest.
Many people like to play tug-of-war with their dog and use rope toys. These are OK for this type of play, but a dog should not be allowed to chew and swallow any type of rope. The strands can block the intestines, they are not digestible. Also be careful of stuffed toys and any product made of cloth. These also can block the dog’s intestines and are not digestible. Many stuffed toys are stuffed with batting that is made of synthetic material, again, not digestible.
If your dog likes to play with stuffed toys, watch him carefully to see if he rips the toy apart to pull out the stuffing or if he is the type of dog that will not destroy the stuffed toy. The key with any type of toy is to know your dog. With care and observation, a dog can play safely with toys.
