My groomer came home last night to groom Mr. Big and Sushi. She set up in the middle of the living room, right in front of me, where I could see and hear everything all the time from the kitchen. Nothin out of the ordinary. Then she took him to the bathroom for his bath. I was not there but didn't sound like there was anything unpleasant going on, Big is very chill in the bath.
Anyways, the groomer left and everythingh was normal, Biggie with a hot new puppy cut.Since this morning, everytime I touch him or try to pick him up he whimpers. He's also shivering. I put a sweater on him and the shivering got better. But he still doesn't like to be picked up, he squeaks.
While he was sitting on my lap I touched him everywhere, no problems. But everytime Missy or Sushi came near him, he would growl at them, very unusual of Mr. Big.
Could it be related to the grooming session last night? there are no cuts or bruises on him. he just seems to be sore. He walks ok, although I did notice a very minor limp a few times, but then again I might be just imagining it because i'm looking for something.
Any idea what I should be looking for? what I should do?
Please please help.
