i have 2 puppies who seem to both have a lump on one side of there jaw, i would say its their glands, however they were seen by a vet 2 wks ago and this lump was not present. also their mother is losing all her fur, she as not nursed the pups for the last 3-4 wks. do you have any suggestions on what could be wrong. All pups and mom are full of live and showing no sign of pain eating and drinking fine too. i dont understand it
