After some advice, if anyone has had a similar experience.
We have two, four and a half month old puppies. One pup is being driven mad by constant itching/scratching/nibbling at his lower legs. (I would say it's the inner back legs) He is constantly nibbling away all night. I'm worried he's going to make himself sore.
We have been to the vets, and she has ruled out fleas, and has prescribed him some shampoo. He's going to the groomers next week, and the vet suggested we ask if they can trim him short round the back leg area.
I'm aware if could possibly be an allergy to either food or the environment. A colleague at work suggested it might be pollen, as he loves playing in the grass.
Any ideas/suggestions on what I can do to help him.
