Zac was found wandering through Cricklewood dangerously underweight

This loveable mastiff-cross looks happy and healthy as he poses for the photographer with his nurse Kerrie Gill.

But just weeks before he was found wandering through Cricklewood, weak, dehydrated and dangerously underweight.

Named Zac, the dog was nursed back to health by vets at the Blue Cross animal hospital in Victoria.

And now they are seeking to reunite him with his owner.
