wolf wont stand

I'm almost certain this ticket is a duplicate of MCPE-33152, but it's hard to be sure given how poor quality it is. If you can verify you are playing on the Java Edition and provide more information about the issue, please leave a comment.

I am playing in 02/08/19 in Java Edition, 1.13.2 version, this also happens to me. After I returned to the game I had saved and left I found my 2 tamed wolves sitting and could not make them stand up again. I had not commanded them to sit before leaving the game and the puppy that was with them was not there anymore, simply dissapeared. I can still feed them though, just can't make them stand up and follow me.
