My puppy has a blood blister after a vet's needle. Is it normal?

Updated on September 23rd, 2025

Pet's info: Dog | Dachshund miniature | Female | unspayed | 6 months old | 11 lbs

Puppy had a lump in her abdomen. Vet did a fine needle aspersion and put it on a slide. Said it showed there was an infection but also saw a couple of funky cells. She was put on two different antibiotics for a week. Where the needle went in there was some redness but by day seven had turned into a blood blister.

The needle likely created a hematoma (blood collection under the skin) from puncturing a small blood vessel during the testing process. This should go away on its own. If it continues to grow in size or persist, I would have the veterinarian that performed the test originally recheck the area. If the mass does not go away, I would send out further testing to the laboratory to help confirm what the mass could be. With Peppa's age, it is likely benign or infectious versus cancerous but there is no way to tell unless a sample is interpreted at a lab further. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
