sorry jj but 4 vets are not going to recommend anyone who is not competent enough to look after dogs, i suggest the problem lay with you/harvey
you have posted many times about harvey's naughtiness, we all look at our pets through rose coloured specs - especially when they have died and you are looking back. take murph for example, she is a lovely sweet fluffy thing with a wonderful friendly temperament... in my head.... in reality shes old, bad tempered and very handy with her claws
if you are unable to look after maxie maybe you should think about returning him to the shelter
