We have a 2 1/2 year old female lab. Early in the spring when we first started mowing she got some red places on her stomach and I used cortisone on them and vet said probably a reaction from the grass cutting. She then got a growth under her jaw that the vet said was something from her food/water dishes and to start using a bleach/water mixture to clean them in and had an ear infection medicine to use on it and it is almost gone, but she still is getting these really red places on her stomach. I get one gone, then another comes up and she is not licking these area. Her stomach is the only place that seems affected. It's almost like she has some skin disease like psoriasis. Has anyone else ran into this and I have not had them checked out with the vet as they go away after awhile when I treat them, but some pretty large areas at times.
