My dog has a lump on her back - what could be the cause?

Answer by  navywriter (790)

Lumps can be something as simple as an infection or caused by a fall or blow to that area of concern. However, they could also be caused by cancer and should be checked out by a veterinarian as soon as possible to be sure.

A lump could be from an insect bite, a reaction to a vaccine, a cyst or a fatty tumor. Most lumps are not serious, but you should have it examined by your veterinarian who can aspirate the lump and check to see if it is a tumor. Skin cancer is very common amongst dogs.

If the lump is symmetrical and feels somewhat soft to the touch it's probably a fatty tumor. Fatty tumors are not dangerous to the dog. You should take care when grooming your dog so that you don't disturb the lump. If the lump is hard to the touch it should be looked at by your vet.

If the lump is hard and stationary, it could be a bone spur. If it is soft, it could be a fluid filled cyst. These can be aspirated by a vet. If she is not in pain, you probably shouldn't worry. Some lumps are fatty tumors from old age.

Many types of dogs get small lipomas (fat deposits) that are benign. You can take her to the vet and have it removed. It is firm but mobile, they may be able to drain it with a needle.
