A Growing Skin Tag on a 10-Year-Old Jack Russell's Cheek

by A reader



Reader Question
Our Jack Russell had what at first was thought to be a tick. Checking it revealed a skin tag slightly above and behind the left upper cheek area. It has grown over the last month or two. It appears to be encapsulated, non-invasive and gives him no discomfort whatsoever. Length is 20mm, width is 13mm and height is 11mm. He is 10 years old and is otherwise very healthy. He eats well and is very active for his age. Do you have an opinion as to what it is and the possible cause?


Answer from Our Team

From your description, it could be a skin tag, a wart, a cyst or a benign skin growth, all of which are common in older dogs and often feel neat and well defined. But some growths that are not benign can also look like this, and the fact that it has clearly grown over a month or two means it's worth having checked.

A rule many veterinary cancer specialists use is to sample any lump that is pea-sized (1 cm) or larger and has been there for a month. At about 2 cm, this one meets that rule. Your vet can usually start with a quick needle sample, which often doesn't need sedation and costs much less than surgery. If it does need to come off, smaller growths on the face are easier to remove completely.

In the meantime, measure it every couple of weeks and take a photo. Go sooner if it grows quickly, bleeds, opens up or starts to bother him.
