My 7mth old Irish Setter has just been diagnosed with this condition in the bone above his left wrist. They believe he may have knocked at some point adding trauma and triggering off this development. He showed a limp the day we collected him from kennels and it got progressively worse on an occasional basis hence trip to vets. Of interest before the return trip to the vet I rang the kennel and he recalls no specific injury event but he did make a comment about him upping his food as he visibly grew over a three day period. Before anybody asks, the kennel is trusted to his word, it's a very small kennel and I use him for occasional training lessons. The vet has said it should heal itself in time without permanent damage and recommends: 1. One month rest, 10min max on lead, per hour 2. Rimadyl phased out over two weeks 3. Change to Giant Dog puppy feed (currently on minced tripe and Skinners for adult mix) Apart from dealing with a 7mth on effective house arrest (we may both kill each other), does anybody else have experience of this? Is it genetic, dietary or trauma linked and should I notify his breeder for her information?
