Pet issues

This might be a bug. Or it's just my minecraft acting weird...

I was going to take my cat for a little walk. I let him walk and ofcourse he sat on the chest. Then I pushed him.
Then bam. He wasn't moving anymore. I right clicked him but nothing happened. Tried to make him follow me but he didn't even tp. Then I pushed him on the bed and pushed him back and he was normal again. And that made waste me 2 minecraft days...

Steps to Reproduce:
1. Push the cat/dog off a chest. (it might be something else caused this to happen. I'm just warning.)
