I'm just intersted to know if anyone knows a "valid" cure for my yellow labs redness on his underbelly and itching, also he has recently developed a "foul" odor. Help.
Staph infection maybe.
I agree with kiddsmom. You need to see your vet who will probably prescribe antibiotics and some kind of shampoo. It could be a contact allergy from something he's laying on or it could be caused by a food allergy. I've found that most vets do not know much about food allergies.
If in doubt, see the vet.
Yep, sounds like staph...need a vet visit.
