His name is Cosmo, he is a neutered male collie cross. He is tri coloured, mostly white and black but has a little bit of tan on his face. He has a unique ear as it flops over (it was damaged), the other points up. I'm not sure what he’s crossed with but he's quit short and stocky and has a chunky face. He has a Dog's Trust collar on and is chipped. He is a very friendly dog and would probably come if called/if there is a biscuit.
Unfortunately my friend is also disabled which means she can't even go and look for him for very long, she has bad Lupus and can only walk as far as the local park before becoming exhausted. The stress and worry of her missing dog is making her worse
This is the best picture I have of him at the moment, it was taken a couple of weeks ago when we went to Berwick on holiday:

Please PM me if you have any information. Thanks for looking.
