I woke up today to find Ein acting strangely. He was fine yesterday when he got the shots, but today, he's not bearing any weight on his rear right foot. He didn't even want to chase after our cat or want to walk outside to go pee. His rear right leg is shakey and he whimpered when I gently touched it. So I carried him to his bed and he's sleeping right now.
He received these shots:
Ein's received them before a year ago, but didn't have any reaction to them.
I was just wondering if this limping and behavior is normal after getting vaccines.
