The groomer told me that I had to get dog vaccinated for canine influenza if I wanted to bring her back in the future. I talked with her vet and he said that it is now on the required list.
I would not take her to a dog park; too protective of my girl. She still needs good bath now and then to wash out the mud.
The vaccination hardly does anything... it’s only for a small amount of varieties of the dog flu. Near useless like the human version.
