Sometimes the answer to, “Why do dogs chew their feet?” is even beneficial. When dogs instinctively lick their wounds (whether on the foot or elsewhere), antibacterial enzymes in their saliva help ward off infection, according to an article on Psychology Today’s website. Saliva also aids in cleaning abrasions and cuts, and the licking action promotes healing by stimulating cells that close the wound.
Please do not ask emergency or other specific medical questions about your pets in the blog comments. As an online informational resource, Preventive Vet is unable to and does not provide specific medical advice or counseling. A thorough physical exam, patient history, and an established veterinary-patient-client relationship is required to provide specific medical advice. If you are worried that your pet is having an emergency or if you have specific medical questions related to your pet’s current or chronic medical conditions, please contact or visit your veterinarian, an animal-specific poison control hotline, or your local emergency veterinary care center.
Puppy chewing is often caused by the fact that either their baby teeth are erupting, or they are being replaced by permanent teeth. The tiny, needle-like teeth erupt when your pooch is around 3 to 8 weeks old, and just when you get used to scratches from nipping, they start teething again. Dogs stop teething when they are around 4 to 6 months old when all of their milk teeth are replaced by adult ones.
A dog’s deciduous teeth will erupt between three to eight weeks of age and around four to six months of age these teeth will be gradually replaced with permanent teeth. Teething is a painful process and puppies chew more during this period of time because their gums are very irritated during this time and the act of chewing relieves their discomfort. Inappropriate chewing is most likely to occur while the puppy is teething but if not corrected can become a long standing problem even after all the adult teeth emerge and teething ends.
Discourage chewing inappropriate items by spraying them with chewing deterrents. When you first use a deterrent, apply a small amount to a piece of tissue or cotton wool. Gently place it directly in your dog’s mouth. Allow him to taste it and then spit it out. If your dog finds the taste unpleasant, he might shake his head, drool or retch. He won’t pick up the piece of tissue or wool again. Ideally, he will have learned the connection between the taste and the odor of the deterrent, and he’ll be more likely to avoid chewing items that smell like it. Spray the deterrent on all objects that you don’t want your dog to chew. Reapply the deterrent every day for two to four weeks. Please realize, however, that successful treatment for destructive chewing will require more than just the use of deterrents. Dogs need to learn what they can chew as well as what they can’t chew.
Indigestible chews like hard plastic or nylon chews: As a rule, any chew that is indigestible has a high chance of causing a gastrointestinal blockage or indigestion at the very least. Hard plastic or nylon dog chews are often too hard and can damage teeth. In addition, they develop rough edges when chewed that can cause injury. These toys are not digestible and cause GI obstruction or damage if eaten.
