Ask a vet online- ‘My 10 year old dog has a lump not sure if I should take him to the vet?’

Question from:

Sheree Lu

My 10 year old dog has a lump around the size between a 10-cent/20-cent (Australian) coin. It’s round, soft to touch and when I touch it, it didn’t seem to cause him any discomfort or pain. It’s located on one of his hind flanks, on his thigh-ish area. Like if he sits down, the lump would be on the ground but it’s not near his anus. I’m not sure if I should take him to the vet..?

Answer by Shanika Winters Online vet

Hi Sheree and thanks for your question, with any lump you find on your pet I would advise that you take your dog to be seen by your vet. I will try and explain in my answer some of the possible causes for the lump and how it can be monitored, treated or removed.

Why has my dog got a small soft lump?

A small soft lump can be caused by an infection, reaction to a parasite/foreign body, swelling in response to an injury/allergy, a tumour or a combination of these.

Infection tends to lead to an area of reddened/hot (inflamed) skin, which may then swell up as it fills with fluid/puss. An infected lump would usually appear over a few days, may be painful to the touch and might burst followed by crusting over. An infected lump may be due to a skin infection, where a parasite has bitten, where a foreign body (e.g. a grass seed or thorn) has entered or is trying to exit or maybe on top of an existing lump…
