Thanks for using Petco Pet Education Center, formerly Petcoach! 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!

    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 an under the skin lump and it is hard what it is?
Thanks for using Boop by Petco! 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 night!

I’m trying to figure out what this mass is under my dogs legpit area. It’s grown over the last week but not sure how long it’s been there. I believe it wasn’t there last month so it’s pretty new.

My dog has a soft bump under skin that seems to move around when you touch it. It's not painful to him. Eating and exercise normal. Someone said it could be a fat tumor. How do I get rid of it?
It could be but many masses can feel alike. To diagnose skin masses we always start with needle aspiration for cytology. This often readily provides a diagnosis for most masses, including lipomas (fattty tumors). Lipomas don't need treatment in most cases unless growing or impeding mobility. But, surgical removal is typically curative for small masses. Other skin masses may require removal for treatment. I hope this helps and thank you for using Boop by Petco!

Hi I was going through my dogs hair and found this and was wondering what it might be. Also he’s developed this in his eye.

The one in his eye is most likely a benign growth as over 85% are benign and usually only removed if bothering the patient. Good luck and have a good night!

Is this something to worry about? Gucci is a 7 year old maltese and shih tzu mix and he has these pimples often. I’ve never seen one burst like this though...
Thanks for using Boop by Petco! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. However, this is likely a benign sebaceous adenoma based on what it looks like.
