Overview
Lactose Intolerance, a common digestive disorder, is caused by the inability to break down the sugar in milk. That undigested sugar forms the perfect environment for bacteria to form in the intestinal tract and attack the stomach. Dog and cat owners should be aware of the symptoms so they can remove all dairy products immediately from their pet’s diet if they think lactose intolerance is at work.
Symptoms of Lactose Intolerance
The most common and overt signs of lactose intolerance are vomiting and diarrhea, which isn’t surprising because the digestive system isn’t working properly. Sometimes a dog will drink excess amounts of water because lactose intolerance can also cause dehydration.
Since lactose intolerance is essentially an allergic reaction, owners should also look for the signs one might more often associate with allergies. For instance, if the dog or cat licks its paws or rubs its face on the floor, then its skin is clearly irritated and itchy, and this could be the result of lactose intolerance if dairy products are indeed a staple of the pet’s diet. It’s also possible that other allergic reactions like a mucus discharge from the eye or nose could occur, although this is less common.
Other dairy products can have a different effect. Cheese, for example, can cause constipation. This problem manifests itself in the dog and/or cat straining to have regular bowel movements and small, hard, and dry feces.
Even puppies and kittens, who can obviously tolerate their mother’s milk, are not necessarily immune to this problem. Puppies and kittens are often allergic to cow’s milk, but not their mother’s milk. This can lead to diarrhea and the pet being unable to wait until it’s outside to have a bowel movement. The best rule of thumb for a dog and/or cat owner is to severely limit or simply eliminate dairy products from their pet’s diet.
