I posted a few weeks ago that I had recently got a dog from the kennels.
He had been abused badly.
Anyway he had bit my boyfriend when he tried to wash him and growled at me and showed teeth for no reason.
Anyway today,he was happy wagging his tail etc
Sat on my boyfriends knee and I went over to stroke his head and he lunged at me (no growling or teeth showing ) and bit my leg then bit my arm.
No blood or broken skin as I had my coat on and jeans.
I'm heartbroken
Do I give him another chance or do I give him up?
