Hello, we just rescued a yorkie from an animal control center. We named him Lucky, we love him. He's been vetted and had a good check-up with the vet, I explained to the vet of his constant sneezing and he gave me a recommendation of giving lucky benadryl (sp?). I dont think it helped much. I also dont want to give this to him everyday. Surely there's something else i can do. He has a constant running nose and sneezing. We have ceramic tile and carpet in 3 of the bedrooms. Any suggestions?
