I took my 2 standard puppies they are 4 and 5 mos. to the groomer and they now have respiratory infections and they gave it to my toy schnauzers. They are all on SMZ tablets. I know that is where they got it because none of my dogs have been anywhere and no dogs have to my house. They sound like they are all sneezing and it's really wet. I have never had a sick dog before and I hate it. The Vet told me places like the groomer and Petsmart have all kinds of illness.
