I recently found a lump on one of my dogs breasts. I don’t know if I should take her to the vet or not, I researched online and I think it might be a memmary tumor .

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address our concern. Judging from the photos, it appears that the mass is associated with the mammary gland. Some dogs can have a larger amount of fat and glandular tissue that is normal and nothing to be concerned about. However, this could be a primary mammary mass that needs further testing. I would recommend having a veterinarian take a look at this so that the most appropriate diagnostic and treatment recommendations can be made. 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.
