Pet's info: Dog | Jack Russell Terrier | Female | spayed | 10 years old | 13 lbs
This bump grew almost overnight on my dog. I am taking her to the vet but they can't get her in until Friday. Any ideas what it could be?

Bumps that appear rapidly are usually some sort of fluid-filled mass. This may simply be a blood blister, but it's also possible that it's a type of tumor that is filled with blood (hemangioma, or hemangiosarcoma). As long as she's otherwise normal, she will be fine to wait until Friday for your vet to look at it. They can inspect it closer and take samples to give you a better idea of what it is. I hope that helps and all is well with Mya.
