Scamp is fine

Went to the vets and the vet said he has epilepsy and has to stay on medication for good.... and the reason he is peeing in the house, losing focus and his back legs are going is because of the valium.
The vet said he'd actually come along better than expected.
I'm really happy

Thanks everyone for your support!
Not completely out of the woods yet... he's still fitting so I'm still cautious.. but all should get better in due course
