Oh and we did an antihistamine trial as well as was hoping this would work so we did 4 different over the counter ones one week each such as benedryl, chlor...,etc and nothing really worked and derm said usually does not work in most dogs but some it helps and if doing antihistamines good to use fatty acids such as cod liver oil as supplement with that
also I do not vaccinate if not necessary I always do titers once year with blood work for all 3 of my dogs as to not over vaccinate. The holistic vet made mention notice this all started after her puppy shots
if they have a weak immune system that is where allergies stem from that and inbreeding - dd is from a breeder too
