oh Max! What to do?

[lovemymix]

He did have vaccinations & I thought it was possible that was why he was a little (lot!!) off today!

[lv4dogs]

He could of just been sore &/or grogy from the vaccines. How has he been doing since?

[dab_20]

Maybe you touched him in the place where he got his vaccines? I know Molli gets very sore there and it hurts her when I touch her where she got the shots.

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.
