It looks like the bump is inline with her mammary chain. Intact females are prone to developing mammary tumors. Is is about a 50% chance of it being malignant. I would recommend surgical removal with biopsy. I usually recommend that the patient also be spayed at the same time to decrease the likelihood of further mammary tumor development.
Best of luck and thank you for using Pet Coach.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. This appears to be a venous varicosity, which simply means an enlarged or engorged vein. Why? Hard to tell. Usually it is due to chronic venous obstruction, similar to what people ( especially women ) would get when they had to stand on their feet on a production line all day long. There are little valves in the veins, & sometimes they break down & the blood just accumulates & pools. You could have it removed, especially if you plan to spay her, but it would be a good idea to consider an angiogram or ultrasound to see if there is an underlying reason why it popped up. If there is some underlying reason for this vein to become congested, other veins may well follow suit. Hope this helps.

My dog has stomach bumps that don't bother her. What are they?

Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like a mammary tumor. This could be a benign or malignant growth. 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 her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

My dog has a painful lump on her stomach near a nipple. What is it?

Hi. This is a very big mass. If it is firm and painful, this is concerning in an unspayed, older pet is cancer unfortunately. Besides a cancer, other possibilities include infection, cyst, lipoma, a benign mammary tumor, hernia, etc. She should be fully checked out and have the mass sampled to get an answer. The sooner the better in this case.

My unspayed female dog has a hard breast lump. What is it?

It is difficult to tell what is going on with Panthera based on the picture alone. The lump in the picture almost looks wet, so I would be concerned about a potential cyst or infected gland. Since she is unspayed, I also worry about potential mammary cancer, which we see more commonly in intact females. It can present as firm masses under the mammary glands. Dogs can also get benign masses of the mammary tissue as well. The best course of action would be to take her to your regular vet to have them evaluate her. She may need a fine needle aspirate of the lump. This is when we take a sample of cells from the area and look at it under the microscope to try to determine what the underlying cause is. It is no more painful than a vaccine and can give a lot of information as to if anything further needs to be done for Panthera or not.

My 1-year-old female dog has lumps under her nipples. What is it?

Hello. This is probably benign mammary hyperplasia, but you do want to have this looked at, especially if she has been spayed. If she has not been spayed & has never been with a male dog, then this could be related to a false pregnancy. Also, has she been in contact with anyone who is on hormone replacement therapy? Sometimes, this can rub off on a pet & cause mammary enlargement. If no outside cause can be found, then have her spayed if that has not already been done, & submit a biopsy to see exactly what is going on with the tissue. Thanks for using Petco Pet Education Center, formerly Petcoach.

What is this worsening growth on my unspayed dog's nipple/belly?

This actually looks like a mammary tumor (breast cancer). Very common in female dogs that have not been spayed. You need to take her to a vet for an exam as soon as you can to have that checked. You may want to take this article to your vet to show them. ( https://www.petcoach.co/article/mammary-cancer-in-dogs/ )

My dog has a lump on her stomach, is it serious and what should I do?

This lump/growth should be ideally examined by your veterinarian to have a definitive diagnosis. Your vet will examine it and possibly perform with an FNA (fine needle aspiration) or a biopsy. Differentials would include skin cyst, infections or benign or malignant type of tumors.

What are the tiny lumps under my unspayed female dog's nipples?

What you are feeling are tumors (breast cancer); very common in dogs that are not spayed. They could be benign or malignant. I can't tell you that. You need to have them surgically removed and sent to a lab for histopathology. She should also be spayed as the same time as the masses are removed.
