Please can anyone help. we have a bully that has had sore paws for months. It is his rear paws not on pads just above that keep getting lumps a bit like blisters and bleeding. We have been back to vet several times  he gets antiobotics and it clears up, vet did some blood tests and said his white cell count was low, and he thought it could be caused by the foxes as we live near the woods. Our last course of medication was our last hope and yes it cleared it up for a week but it has just come back again going to vet tomorrow and further test are going to be carried out exray and not sure what else. Has anyone experienced anything like it . Thanks
