Why does my senior dog's breast lump fluctuate and reappear?

This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Roxy to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

It looks like Roxy could have a mass and/or an infection. She needs to be examined by a vet to determine the cause and treat. Your vet can do a needle aspirate and/or biopsy to help diagnose and then treat. It may need to be removed.

This lump could be a cyst or an abscess. I recommend taking Roxy into the vet tomorrow for an exam. The vet can do a physical exam, and can do a fine needle aspirate on the lump. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. If it is a cyst, it will need to be drained, and it may need to be removed in order to keep it from returning. An abscess will require it to be drained and flushed sterilely, and she would need antibiotics to treat the infection.

That looks like a growth, not a nipple. In a dog Rocco's age, there is always a chance any growth can be malignant and if it is, it does need to be removed surgically. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I would give his vet a call to make him an appointment to be seen in the next couple of days. Best of luck.

Thanks for using Petco Pet Education Center, formerly Petcoach! I would recommend Roxy be evaluated by a veterinarian as soon as possible. If they are enlarged lymph nodes throughout her body, it could be due to a development of lymphoma, or an infectious disease, for example. An early diagnosis of either (or another underlying issue) would be very beneficial for treatment. I would recommend she be evaluated by her regular veterinarian, and any necessary testing done. Good luck!

A lump that large that shows up quickly is concerning to me. It could be related to infection, a hematoma, or cancerous so I'd recommend getting Rosie examined by a veterinarian as soon as possible. Your veterinarian can take a small needle sample of the lump to decide if it's something that requires treatment or surgical removal. Thanks for using Petco Pet Education Center, formerly Petcoach and I'm hoping for the best possible outcome for Rosie!

It could be a growth of some sorts. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I would give Duchess's vet a call to make her an appointment. Best of luck.
