Lumps & Bumps

4 Apr 2019

A regular reason a pet owner might come to see us is because they have felt a lump on their pet whilst petting or grooming them.

Swellings and lumps can be a real worry.  Owners automatically assume that a swelling is something terrible but more often than not this isn’t the case.

So what are the different types of lumps that your pet could have?Sample Pots


  • Warts – these can be caused by a virus with some needing treatment. Most just appear and disappear on their own.
  • Cysts – these commonly appear between the toes or under sweat glands on the skin.
  • Ticks – these can look like moles or skin tags sometimes .
  • Lipomas – these are harmless fatty lumps that can appear anywhere on the body.
  • Insects – bite or stings.
  • Abscesses – are more common in cats and rabbits and usually present as a hot lump that has puss under the skin or discharge from it.
  • Mast cell tumours – these lumps on the skin are sometimes malignant and need to be removed straight away.
  • Mammary tumours – these are lumps under or close to the nipple area.
  • Testicular tumours – these are lumps on the testicles of uncastrated males and can be benign (harmless) or malignant (cancerous).


If a lump seems painful, has any discharge from it or is affecting your pet’s mobility then seeking veterinary help is a must.  In some cases it can be very difficult to be certain what a lump is without further tests so we may recommend a biopsy so that the lump can be more closely examined under a microscope.

Knowing what you’re dealing with and what the treatment options are (if any) can go a long way to putting your mind at rest, so if you find a lump, come and get it checked.
