My dog has a red bump on his leg after blood work. Is it serious?

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.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Bobo. This bump could be a cyst that has now ruptured, or it would be a benign or malignant growth. It may be bleeding because he's been picking at it. Apply gentle pressure to stop the bleeding, then put a bandage on it to protect it. Take him into the vet in the morning to get it diagnosed and treated. Best of luck.

Hello, thank you for your question about Sky. Based on the photo you've attached it is possible that this lesion is secondary to a blood blister or cyst-like lesion. It could also be a mild skin infection. Dogs can develop skin masses/tumors such as mast cell tumors. I would recommend having Sky seen by your veterinarian so that they can examine the area and discuss the need for additional testing such as an impression of the area or collecting a small needle sample. Hope this helps!

This looks like it could be a hemangioma, which is a benign 'blood blister' type skin lesion, or it might be an insect bite or site of previous trauma. It would be a good idea to have your vet take a look in person if it has not resolved in the next week or so or if it seems to be bothering Bear.

Hi, thanks for using PetCoach! Poor Moco! Due to his age, the appearance and the location it looks like a histiocytoma. Which is a benign mass in young dogs. They tend to resolve on their own in a few months but sometimes if they ulcerate, grow rapidly, become infected or bleed we recommend removing them. Another possibility is a mast cell tumor. I would suggest having it looked at my your vet. Good luck! https://www.petcoach.co/article/histiocytoma-in-dogs/

Ouch! Definitely something that should be checked out by your regular vet ASAP. Certain types of tumors such as mast cell tumors, hemangiomas, injuries, blood blisters, etc can all appear like this, and so it should be looked at and biopsied to see what is going on. Until you can get to your vet in the morning, keeping Berkeley from licking or chewing on the spot with an Elizabethan (cone) collar is best to reduce any further injury or irritation.

This can be one of two things: 1) a small abscess that has ruptured. 2) a small tumor that did not have enough room to grow and therefore started to ulcerate and finally ruptured. Since it is on a leg and deep, you should have your veterinarian have a look at it, to see whether any vital structures are involved and whether it is a tumor that needs to be removed.
