Hi dog been limping the past days but seemed ok in himself. Tried to look last night but warned us off by barking/ threatening to bite us. He was Spritely though. However this morning he looks really ill. Ignored his food and went into bushes. Brought him in the house and seems happy with that. Got a vets appointment later. Do you think it's cos he's in pain or do you think it might be infected? His front paw is the issue but today he has a hunched back and seemed to be struggling to sit. Can't work out if he's just got ill on top of his sore paw and it's allCoincidence
