Hi-9 year old JRT bitch-fit and well. This lump appeared on her chin yesterday. Its hard and immobile and doesnt seem to bother her if you touch it. Shes got no temperature, eating and drinking as normal and nice cold wet nose. Shes going to the vet tomorrow, but had anyone got any idea what it is? My finger is in the pic to give you an idea of size. Many thanks guys !!
