oh Max! What to do?

[beyond_me]

They do say that when a dog gets vaccines thay can have mood swings. Or the day before could have been a lot for him and he is grumpy today.

What has happened since??
I can even see when putting on the leash if you were anywhere close to his vaccine spot, he would be upset.
It's not behaviour he should get away with, but the reasons suggested might be why he acted the way he did.
