You can give benadryl to help 1mg per pound, but you have to identify what is causing them whether it is environmental or food related allergies. What are you feeding Nacho and has anything changed recently?
I feed him fromm the lamb kind, and I think it's enviromental, I had brought him to the in laws for a day yesterday and now today it has it so maybe it was caught there?. But he started eating and I showered him with tea tree shampoo
Todd -- got you covered oon the benedryl... you can also, if you think it is environmental, wipe his paws, face and belly with a wash cloth to remove what could be causing the issue
