I recommend Hill's prescription Diet RD brand dog food. It is a very high fiber, low calorie food that you can feed your dog to attain their optimum weight. As you change over to this food, do it gradually over a a period of two weeks. One sign you will see in your dog along with the weight loss is an increase in frequencyand amounts of stool produced. I also recommend Derm Caps an Omega 3.6 fatty acid supplement to maintain a good shinny hair coat to compensate for the low fat diet.
Allergies can be the most frustrating condition the owner and a veterinarian can treat.
The owner and veterinarian need to put on their Sherlock Holmes caps to solve this mystery. Atopy or inhaled allergies to pollens, trees, dust, etc usually has the dog licking his paws, rubbing his face, and blisters occur at the site of contact with scratching and licking being the most common clinical signs. Flea allergy is a hypersensitivity to flea saliva, that makes the dog bite and scratch his back and around the tail. So now that the information is in front of you how do you diagnose and treat the problem. If the dog has fleas and they bites constantly, we can safely suggest the latest treatment in flea control plus the occasional cortisone to relieve the scratching.
