I have done some research, and found out that most of the pet foods found in stores, like walmart, target, etc, is harmful to dogs, because of the ingredients in them.
I wish I would have known this before feeding my dogs alpo all the time for 8 months now. My dog is only a yr old, and she has problem, I now believe it to be the cause of toxins, in her body from the food I have been giving her.
This food can also cause allergies, hot spots, and lots more.
Here is a link to find out more, and do the research also. The more you know the better for your pets.
