My dog has a pink bubble-like bump in her armpit. Is it serious?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. Given his young age, this could just be a small abscess or site of infection. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! The area looks moist so it is likely a superficial skin infection or hot spot. I would wash the area with water and mild soap and apply a triple antibiotic ointment twice daily. The area does look a bit swollen so watch it closely. If there is no improvement over the weekend have her checked by your Vet Monday. I hope this helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! Based on its appearance, this could be a benign or malignant mass. This is most of the time differentiated with a test called a fine needle aspirate which is easy, cheap and pain-free. Sometimes, a biopsy is required for a diagnosis. Have Panzer evaluated by your veterinarian to have this test performed to try to sort out what the diagnosis is so that the best course of action can be determined. Keeping my fingers crossed that it is something benign!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! It could be a wound from trauma, tick/insect bite, or a histiocytoma. Histiocytoma’s are benign growths on young dogs that are pink raised button like masses that can ulcerate. They tend to form more often on the limbs. They also tend to go away on their own in a few months. You can clean it and apply an antibiotic cream and prevent licking up see if it resolves. It it persists or grows I’d have your vet look at it. I wish Luna the best!

Hi there and thank you for using Pet Coach to address your concern. With Stella's age, I would suspect this is likely benign and what we call a histiocytoma. To be on the safe side though, I would recommend having your veterinarian take a look at this and perform additional testing to help better determine what it could be. Your vet can insert a small needle into the mass and look at the cells under the microscope to help rule out what it could be. A histiocytoma is a benign (non cancerous) tumor that usually resolves on its own over time. I hope this helps! Please let me know if you have any other questions or concerns. I am also available via consultation if needed.

I would recommend having this examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. The veterinarian can take a sample with a small needle and view the cells under the microscope for a better idea of what this is. It might be a benign or malignant tumor. It would be best to have this checked out physically. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
