Bruiser had his last set of puppy shots today. He goes back for his rabies next month. We never have had a problem. No sleepy, whiny, or otherwise behaviors. Today, however was a little different.
He did his usual yelp when she gave the vac. Got in the truck no problem. We went on a mini walk when we got home, and in to the Xpen while I took my daughter to the pumpkin patch. When I got home tonight, I picked him up over the top of the pen and he yelped. Went to snuggle my neck, yelp. And few more times since then. I'm at a loss, he can run and jump, climb the stairs, crawl under the base of the table to grab a stray strand of pumpkin guts, but yelps when picked up.
I was wondering if it just a nervous reaction, but it sounds like pain.
