My 3 Rotties have a corn allergy. Does anyone have any Theory why?
The only thing I can come up with is the topical flea medicine they were given at the vet.
My boys were all fine and healthy with no allergies. They never had flea's. They had the run of a big back yard and really no contact with dogs who had fleas.
One day when they were about 18 months old, a stray managed to get in the yard. He was with us for about a week until we found his owner. Needless to say, he HAD fleas. We gave everybody a bath, but we still had some in the house... After a good cleaning we managed to get rid of everything, no sprays or chemicals. Just a lot of washing and vacuuming.
On the next visit to the vet we asked about what to do to prevent this from happening again and he said that he would dose them... I'm sorry to say I don't remember what brand he used. But within 2 weeks they all had terrible sores on their necks, butts, armpits...
We went back to the vet and he said it was contact dermatitis, probably from some plant in the yard. Gave us antibiotics and creams. He said it would clear us as soon as we got a hard freeze.
Well, it didn't clear up, kept coming back. So we started doing research on what may be causing it. We came upon some articles describing food allergies and specifically corn allergies.
We switched to a diet without corn and everybody cleared up within a week or so. Still a few stubborn spots that lasted a month, but what a big difference right away.
I know that maybe it COULD have been something else that was in the food. But about 6 months ago they managed to get a big box of corn chips down off of the top of the fridge when we were not home. And BAM - Within 3 days the sores were back worse than ever. 2-1/2 years with no problem and 1 box of chips between 3 dogs and the situation was right back where we started.
We suspected that there must have been something other than "weeds in the yard" explanation we had gotten from that vet, so we have not been back to him since. And the new guy says he has no idea what the first outbreak was caused by as he didn't see them at the time.
So I guess my ultimate question is - Has anyone else had problems with allergies after the application of topical flea/tick medication?? The ones that come in a small tube and you put between the shoulder blades???
Any information or theories will be gladly appreciated.
