While my dogs don't have any food allergies, my friend's dog has a 'very sensitive' stomach. By this I mean the dog, Roxy, has diarrhea often and lots of gas. When I asked my friend what she fed her dog, I found out it was a rather low grade supermarket dog food.
Of course I extolled on the praises of making your own dog food, to which she balked. So I then asked her to take a look at a hypoallergenic dog food. She didn't realize that the diarrhea and gas are symptoms of food sensitivities, and sometimes even dog food allergies.
So we took a look online at some hypoallergenic dog foods that she could try. And she bought a bag of Sojo's Complete cause she liked the ingredients and the company as a whole.
Well, she fed it for a month and couldn't believe the difference it made. At first, she was a little upset that everything didn't change in just a few days. Honestly, it took over a week before she noticed that there was less dog gas. After a month of absolutely no diarrhea, she was hooked. And Roxy looks so much healthier - she has more energy and her coat looks fantastic.
If your dog is showing signs of dog allergies, definitely try a hypoallergenic dog food. It not only helps with food allergies/sensitivities, but also makes your dog healthier by using quality ingredients, enabling your dog to better fight off whatever allergens are bothering them.
