wow thats shocking!
We recently ended up with a lil mutt, staffy x bullterrier
Long story short, went to have a look at a portable cot and ended up coming home with one of 3 very mistreated pups.
They claimed their papered staffy was jumped by a friends bullterrier, and the guy thought mutts were worthless and had runied his female etc etc etc blah blah....
They were all filthy, literally covered in fleas and skin over bone.
Basically i left with a pup and not the cot. (wasnt worth it anyway)
As soon as i had the lil guy home, he was fed (could see his ribs and his backside sticking out etc) wormed, got rid of all his fleas and bathed him.
2 weeks later, boris has put on weight, his fur is growing back from the bald patches from scratching and hes doing fine and hes the most adorable affectionate lil guy!
His favourite nap spot is in front of the rocker at my daughters feet
