What is this red bump on my dog's paw that turns white when pressed?

Updated on September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Female | spayed | 1 year and 1 month old | 6 lbs

My young dog is a little over a year and she has a small bump on her left front leg near her paw. It feels like a blister but harder and it doesn’t seem to bother her. It’s red but when I press on it, it turns white. I’m not really sure what to do because it’s not hurting her or anything.

Hi there.

This is most likely a histiocytoma. They will often regress on their own within a few weeks to a month. My suggestion would be to take Hazel to your vet for an exam so you can get a more definitive diagnosis. Here is a link to an article about this type of mass.
