So Maggie is really well trained she loves the vet usually. Today was bad. We had to get some vaccinations for her to get groomed. Well to the do it yourself dog wash. She almost bite the vet didn't want me holding her down and I grabbed her head and to full put her between my legs and hold her there. I went to a cat rescue and animal services a up here that does all vaccinations, they didn't seem to be dog people. Maybe that as it I don't know. What should I do in the future? All my dogs in the past were very calm and liked the vet. She has been really good until today. Should I get a muzzle or no?
