There are numerous causes of lumps on a puppies skin. If Bella has been microchipped (this is usually done between the shoulder blades), it could be the chip you are feeling. Other causes are cysts, scar tissue, inflammation after a vaccine, and tumors. I would recommend taking Bella in to your local vet to have this lump evaluated. If it is her microchip, it is not a problem. If it is something else, your veterinarian can do a fine needle aspirate to try to get a sample of cells from this lump to determine what it is. This is not a painful procedure and similar to her getting a vaccine.

    If Bella has a microchip this may be what you are feeling. However the only way to know for sure what it is is to have it examined by your veterinarian. If she is not microchipped I would recommend taking her to be seen so that it can be evaluated.

My 9 week old corgipoo has some sort of weird lump under his skin. It’s around his shoulder blade, under the skin (there are no signs of visible irritation- like redness), it feels to be a bit of an irregular shape (maybe 1/4 inch long), and one part
This is a common location for a vaccine to be given. Has he recently had puppy vaccines? If so, this is likely just a local reaction and no big deal. You can keep watching it. If he hasn’t had shots recently or if you don’t think a vaccine was given there or if it is growing, I would have your vet take a look at it before his next set of shots. Your vet will be able to do a cytology if needed and determine the type of mass it is. I hope this helps!

My 8 month old puppy had 3 small lumps under her skin. One is just under 1cm x .5cm and the other 2 are probably under .5cm . You can't see them on the skin but they are oval shape and move under the skin on her left side toward her back. I'm unsure
In a young puppy like Mia, malignant tumors are extremely rare, and I don't think they would necessary be anything to worry about at this point it time. From your description, the lumps do sound very small, and you did the right thing by having them seen by a vet. It could be that these lumps are benign tumors or cysts, and I would keep an eye on them for now. It's good that there are measurements on them, and if they appear to get bigger, I would have Mia seen by the vet again to have a fine needle aspirate done on them. If they don't grow and/or don't cause her any problems, I would not be concerned about them. I hope this helps put your mind at ease :-)

My dog has a two lumps small lumps under it skin and moves about. what is it
Thanks for using Boop by Petco! These could be benign or malignant growths. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have your pup evaluated by a veterinarian for further assessment and treatment. Good luck and have a good day!

Hey I have a bulldog puppy and I just noticed tonight she has a small lump under her skin above her shoulder
There are many possible reasons for lumps and bumps in puppies, more information on her age, recent treatments and accidents/injuries would be helpful in determining possible causes. Schedule a check up with your vet if you are concerned or it is growing in size

I found this red lump on my dog?
Ouch! I'd have that checked out by your vet in person, especially if it appeared suddenly or is bothersome to Bella. They can take a sample of the spot to rule out any more serious issues such as tumor growths, infections that need treatment, cysts, or see if it's something benign such as a skin tag or other small growth. Until you can get into your vet, it's a good idea to keep the area clean and dry, and monitor it for any signs of changes such as oozing debris, having irregular margins, worsening, etc, as these can all help your vet pinpoint the cause. An Elizabethan (cone) collar can also keep Bella from licking or chewing at it which can reduce irritation and prevent a secondary bacterial infection from taking hold.

Why does my dog have a bump underneath her chest by her private area?
Thanks for using Boop by Petco! Without seeing Bella and feeling the lump it’s hard to say what it is. Dogs can get fatty lumps and cysts that are not serious but they can also get masses that are serious. I would take her to the vet when they open next so they can examine it closer. They may need to get a sample from the lump and look at it under a microscope for a better idea. Good luck and kisses to Bella!

My 6 months old daschund dog has got two lumps symmetrically under skin which cant be seen but by touch and it is normal and lump is movable and soft on touch.
At Chotu's age, these lumps could be cysts or lipomas. 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'd give his vet a call to make him an appointment. Best of luck.

Hi, I have an 11 month old Shih Tzu & I have just found a soft lump that moves on her chest under the skin? It's not a large lump but it's not a tiny lump either if that makes sense? Should I be worried at all? It doesn't seem to cause her any pain w
In a young dog like Bow, this lump could be a cyst, a lipoma, or a benign tumor. I wouldn't be worried about it, but I would have her seen by a vet for it.

It could be a histiocytoma which is a benign skin tumor that is usually seen in young dogs. The tumor usually spontaneously goes away without treatment. Your vet can do a fine needle aspirate to determine the cause and if treatment is needed.

Egg sized, egg shaped lump on my older (probably 8 yr old) German Shep/Dobbie mix. It's under the skin and firm. Any ideas to keep me calm until I can get her into the vet this week?
There are numerous causes of lumps on a dog Sheba's age, and not all are worrisome. Dogs can develop non-cancerous lumps like cysts, seromas (pockets of fluid), abscesses, and bruises. Some of these can go away after being drained by a veterinarian. Dogs can also develop lipomas, which are benign fatty tumors, that generally do not cause problems. Some owners elect to remove them and some monitor them at home. The best way to figure out what is going on is to take Sheba in to have your vet examine her and possibly do a fine needle aspirate of this lump, which involves sticking a small needle into the lump and trying to remove cells/fluid. These cells/fluid can then be examined under the microscope to help determine what the lump is made of and how it needs to be treated.
