Monty started really scratching and licking his belly last night and this morning. He usually only does this if there is a tick that attached despite his Frontline. I looked and didn't see any ticks but it seems his belly is full of pink spots-like hives. He is also scratching near his back leg on his side but I can't see his skin through his fur coat. I put cortisone cream on the belly but that only worked for an hour or so.
I just gave him one benadryl (25mg) pill to see if that will help.
Any idea what it could be? Should I be worried or just monitor? Of course I am supposed to board him tonight and I don't want it to be anything contagious for the other dogs. The only thing I can think of is dry skin because I had to give him a bath the other day and because of the weather (snow & ice) his belly keeps getting wet and with it being cold it can't feel good. Also could street salt be a reason? I try to wipe him down when he comes in from walks.
Thank you for any advice.
