Thank you to everyone! Your ideas are great and I'm going to try switching his food to Natural Balance, hopefully that will help! I have washed all of his bedding in non allergenic soap and he is clearing up finally, I also removed all snacks with wheat in them. I think the wheat was a problem. Funny how he will get this then clear up only to get it again in maybe 2 or 3 months, but this is the worst he has been bumpy for over 4 days and he wants to be cuddled and cries out every now and then and kicks his rear legs out like a mule. Or he will jump up and and scream and try to bite at this back thighs where the lumps are, so I know he is miserable and his misery has kept me awake worrying for over 3 nights! Well we will keep trying until he clears up! Thanks again to everyone for the help!

Thanks for trying to help, I'll keep the site posted as to what I find out.

Can the cold give him bumps and welts? It is very wet oustide and the ground is covered with snow but this happened in the summer too?

Thank you for responding, at first we thought it was a bite in the summer I thought it was a Bee sting but now here in Colorado we have about 7 inches of snow outside so there are no mosquitos or bees? The food he is on is the Canadea (spell?) which is supposed to be the best for allergie prone dogs.

My Basenji has in the last year developed an allergy to something??? He gets these hive like welts and they make him nuts. I took him to the vet and he gave him a steriod shot and a Benadryl this cleared things up but every now and then it happens again?? Right now he has developed the welts on his belly and thighs and some on his face (around the eyes and top of the head). I have been giving him an antihistamine when it gets bad and he seems to be itchy, but it's not getting better. I've heard reference to hot spots? I don't know what those are, is that when they loose their hair, this is not the case with my Basenji. He is only bumpy and itchy with welts. Can anyone offer HELPFUL suggestions?
