My sister has a nine/ten month old BF boy.

Sadly he has a biting/chewing issue. She has a two year old grand-daughter and is very worried that the dog will bite the child (he bites everything/one else!). They're not big bites, more young dog not properly trained type bites, but sister freely admits that she does not have the knowledge or skills to train him.

Today he has chewed through computer wires, so is in the dog house.

Sis loves the dog and has been trying with him, but has now admitted defeat

I would take him in, but we still have the four dogs that were meant to be an interim rescue five years ago...

So, any suggestions anyone?
