Your Senior Dog and Food Allergies
The most frequent allergies are to foods that have been in dog foods for years. The advice from nutritionists is that a variety of foods from a young age will help prevent allergies. This is good news for your dog if you do this before he ages. Just as in humans, the older the dog is the more likely he is to have allergies. Time and the same food for years are enemies of your respiratory health in reference to allergies. There are common signs to alert you that your dog may have allergies.
These signs are itchy skin, red itchy paws, chewing paws, yeast infections, and ear infections. Also, skin infections that return after treatment with antibiotics have stopped. This means you need to change your dog's food periodically. That means that the main ingredient should differ from the previous food. It's pretty straightforward; if the main ingredient in his food has been beef, then switch to a main ingredient of chicken, lamb, or turkey. You may wonder if you need to change brands every time. No. But many of the ingredients should be different, especially the main one. Changing every three months is a good ratio.
Some people think changing dog foods periodically will make their dog picky. Well, no it won't. It will help him stay interested in his diet. Dogs get bored too. And some dog's stomachs don't get upset when you change the food, but to be sure that this allergy prevention method doesn't upset your dog's digestive tract, do it gradually each time as stated above.
