If your dog is constantly scratching and biting, the first thing to do is to see his veterinarian and follow his advice. In general, itching is usually a sign of allergies. And now a days allergies are very common in dogs. Here are a few things you can do to help your pet deal with the scratching and itching.
Make a diet change. Your dog's diet needs to be as pure, organic, and as natural as possible. Make sure there are no additives, food colorings, preservatives and other chemicals in his food. Many dogs are allergic to these additives. Some are allergic to grains. Try a grain free dog food and see if that helps.
Buy a top notch dog food. These are available without additives and with high quality ingredients. You can find them online or in a health food store or natural pet food store.
Or, look up some recipes and make your own dog food. Just changing his food may alleviate most of the itching, scratching and discomfort in your dog.
Add digestive enzymes to his food. There are many enzymes made especially for dogs. As your dog ages he will need digestive enzymes even with the best dog food.
Add essential fatty acids to your dog's diet. Omega 3 fatty acids from fish oil will decrease inflammation and help with the itching.
Vitamin E should be given orally and may be applied topically.
You can buy online or from a holistic veterinarian specially formulated herbs for itchy, dry skin. Herbal formulas are available for both oral and topical use.
Zinc may relieve the itchy feeling your dog has. Some skin rashes respond to Vitamin C.
Feed your dog a high quality food. Add some omega 3 fatty acids, vitamin E, zinc and herbal preparations and your dog may finally get rid of that itching sensation. He will be a happier dog and love you even more.
