My 4 year old pit survived parvo shortly after he turned 1. That was 3 years ago and ever since he has had a terrible stench. It doesn't matter how often or what I bath him in, the smell never goes away. I've noticed over the years that when he eats dog food with any kind of soy/soybean meal in it he chews himself raw and stinks even more. When I actually figured out that it was a soy allergy, I avoided any food (which is ridiculously hard) that contains it. I honestly don't know what to do anymore! I'm not sure if there is any connection between the parvo and the soy allergy that might cause this problem but I figured it was worth mentioning. There aren't any vets around the area l live that are willing to evaluate him due to his breed, so I'm at a loss. My carpets and furniture have been cleaned so much anymore it doesn't even seem to help, I swear, it's almost permanent. If anyone has any ideas on how to cure the stench, please, please input your advice!
