I've been having some issues with Bullet and a semi-severe rash on his belly. It doesn't seem to bother him at all, I never see him licking or scratching at it, it doesn't bother him when I touch it, and it's not oozy/lumpy/gross either. It popped up as soon as summer came around and everything started blooming. I brought him to the vet several times for it, but all they are doing is giving me meds and sending me home. It will clear up with the meds, but as soon as I stop them, it comes right back. I'm pretty positive it's seasonal allergies, because it always gets worse when he's outside a lot and running through the grass/bushes in my back yard. I found some allergy tablets at walmart that I gave to him for a little while. It seemed to help, but I didn't want to give them to him for too long. The active ingredient is Diphenhydramine HCl 25mg as an antihystamine. I really don't want to have to take him back to the vet again and spend almost $200 for a visit and meds and still get the same results. Does anyone know of any OTC antihystamine or allergy meds I could give him that are safe for long-time use? Here's a picture of what his belly looks like now, this is how it gets, then goes away with meds and comes right back as soon as I stop meds. Any suggestions?
