It is difficult to determine what the lumps are just by looking at them. It is best for you to have your local vet examine them. The vet will likely want to do an aspirate of the masses to help determine what they are. They may be something benign like a fatty tumor but they could also be malignant. You need to know what types of tumors they are so you can know what is the best way to treat them. https://pethelpful.com/dogs/About-Dog-Fine-Needle-Aspiration Hope this helps. Best wishes.

    Thanks for using Petco Pet Education Center, formerly Petcoach! This could actually be a normal anatomical structure that you perhaps had not seen before. You can check to see if it is in the other side as well. If there is something similar on the other side then that makes it more likely to be a normal finding. Otherwise it 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 him evaluated by your veterinarian for further assessment and treatment. At that time they can also tell you if it really seems to be a lump or not. I am really hoping for something benign. Good luck and have a good night!

Hi I noticed this lump on my dogs belly this morning and I would like to know if it is anything serious. I haven’t noticed any change in her behaviour though she is still playing and jumping around as normal. Thanks.
It could be a lipoma (benign fatty tumor), but it is difficult to determine by just looking at an image. Ideally, Molly should be seen by your veterinarian. A fine needle aspirate can be done to collect samples for pathology. Treatment options can be discussed once results are returned. The other option would be to simply monitor it at home. Watch for rapid change or growth, pain associated with the mass or restriction of movement. Use an e-collar (cone) if she is licking at it. Whether it turns out to be benign or not, removal while still relatively small is recommended.

Could you give me some advice on what this could possibly be? It’s on my boxer dog (age 7) belly.
That looks to be a mass. A mass is a collection of cells which can be benign (inflammation, benign tumor) or a malignant tumor. The only way to know what it is is for your vet to sample it. Typically we start with a needle aspiration for cytology to the lab. In most instances this can help diagnose whether a mass needs to be removed surgically. In some instances needle sampling will not yield a diagnosis and then the options would be removal with biopsy or monitoring. I hope this helps and thank you for using Boop by Petco!

My dog has a lump on her stomach.
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.

My dog has a growth on her belly. It's been there for years. Recently it has started growing really fast. She is almost 12 years old. What could it be?
This growth on your dog could be a benign tumor or a malignant tumor. Any suspicious growth should be examined by a vet. The vet can do a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the growth to get a sample of its cells, and examines the cells on a slide under a microscope. It's typically painless to the dog and relatively quick and easy to perform. I would have your dog seen by a vet on Monday to have the growth examined and diagnoses so it can be treated.

This mass seems to be a mammary gland tumor but it needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration).

Give Kilroy's vet a call in the morning to make him an appointment.

I am sorry to hear about your concern for Mia! A photo may help give us a little more information about what could be going on with her. A lump could be something like an abscess or site of infection, a hernia (a small hole in the muscle wall of the abdomen where internal structures or fat may poke through), or a mass (we can have benign masses/tumors such as lipomas that are just fat and not a health concern and we can have masses/tumors that are malignant and can spread and require removal). I would recommend taking her in for your vet to examine the area. They may recommend what is called a "needle aspirate" where a small needle is inserted into the mass to collect cells to help determine the cause of the lump.

Hi my dog has a swollen red lump on her under belly and I was wondering what it could be. Also she has like wee spots not far from the lump thanks
This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Differentials include skin cysts, infections, benign or more sinister type of tumors.

These are masses (tumors) that should be examined by your vet. Just by looking at them it is not possible to determine whether they are malignant or benign, but your vet can do a so-called FNA (Fine Needle Aspirate) where he takes a little bit of tissue of the growth with a very fine injection needle (usually does not hurt) and sends it to a laboratory to determine malignancy. Please make and appointment with your veterinarian for an exam.

There are a couple of things this lump on Heidi could be such as a benign tumor, a cyst, or a malignant tumor. Unfortunately without seeing her in person, I can't say for certain what it is, so I recommend a vet visit. 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 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. I would take her into the vet in the next couple of days to have this lump examined and diagnosed so it can be treated as need. Best of luck!
