We have recently rehomed a border collie and he has not been looked after at all, His nails are in need of a good cut he has bold patches on his back end and also has a broken tooth, He is a very nervous dog and very under weight, Got vets on Thurs so he can have a complete health check will keep you informed *sad*
Aw sounds like he has been through a lot, could just be hes been stressed and chewing at himself. Hope all goes well at the vets.
Good luck, hope its nothing too serious waggingd
How did it go at the vets?
