I would not worry to much about this small growth on Daisy. This could be something very minor like a cyst. I would monitor it. If it grows or changes in any way then I would have your veterinarian take an aspirate of it. Thank you for using Petco Pet Education Center, formerly Petcoach.

    These bumps could be several types of things including benign growths like sebaceous cysts or something more worrisome like mast cell tumors. Unfortunately the only way to know for sure is to have a veterinarian take a small needle sample or biopsy for examination under a microscope. I'd recommend having Gertie checked out by a veterinarian to ensure these growths do not need to be surgically removed. At minimum, you should closely monitor the size, shape, and color of these growths and if they are changing Gertie should have these sites biopsied.

    That looks like a healing open wound but to be safe I would get your vet to check it, especially if it's come up suddenly or has changed size, shape, texture recently. She is young to have malignant growths but it's not unheard of even in younger dogs.

    Any lump which is raised, ulcerated/scabbing, has any discharge , rapid growing or painful should be checked by your vet. This appears to be the case and i recommend you get Daisy checked and the growth may need to undergo testing to determine the underlying nature

    Thank you for using Petco Pet Education Center, formerly Petcoach! Bella is adorable! I can see that she has what appears to be a lump beneath the fur on her shoulder. This can be a growth or an infection, but it is impossible to tell from a photo. I recommend taking her to the vet right away. Your vet can take a small sample of the lump to determine exactly what it is as well as perform x-rays and bloodwork to rule out the conditions you are concerned about.

I found a small white bump on my dogs pad. It doesn’t seem to hurt even when I touch it, I’m just wondering what it could be.
Hello. This looks like a small cyst, nothing too worrisome. It may pop & if it does, just clean the area with a good skin antiseptic like Hibiclens ( available at all pharmacies ). A warm compress or soaking the foot in warm water for 10 minutes 2-3 times per day may bring things to a head sooner, but this does not appear to be at all dangerous. Thanks for using Boop by Petco.

Just noticed a small white bump on my dogs nose. When I touch it frels kind of raised. It’s white. Should I be worried?? You can see it in the photo on his nose
Hello. I would not be too worried about this. Just watch the area, perhaps clean it several times a day with an antimicrobial wash like Hibiclens ( available at all pharmacies ) & if it enlarges or changes, see your vet. But it does not look too worrisome. Thanks for using Boop by Petco.

My 7 year old lab mix has this odd bump on his side, should i be worried?
Not unless it causes pain or impedes motion or breathing. You can monitor it for rapid change or growth. If necessary, your veterinarian can do a simple fine needle aspirate in the clinic to collect a sample for pathology to determine the nature of the lump.

My bordercollie is 4 years old and we just found a white bump above his tail. It looks like a wart, doesn't seem to bother him. Should I be concerned?
If the bump is fairly small, not inflamed, and nonpainful then I would not worry about it. It is common for dogs to get lumps and bumps as they age. Keep a close eye on it for now. If you notice it getting any bigger or bothering Indie then you can take her into your vet to have it checked out. I hope this helps. Thanks for using Boop by Petco. Best of luck!

My dog has a little bump on his side. I felt it through his fur. It doesn’t cause pain. What is the cause and should I be worried?
Most small bumps like this are no cause for concern. It could be a small abscess, tumor, or cyst. The only way to know for sure is to have your veterinarian examine Ollie. He/she may want to take a sample from the mass with a needle and look at cells under the microscope for a diagnosis. This way you know if it is serious and needs to be removed, or if it is a harmless bump that is unlikely to cause any issues. This is not an emergency, and if it is not growing rapidly you can just wait for now and see if it goes away on its own. Hope that helps!

My dogs has a small bump on his chest. What is it a health risk?
Hello, thank you for using Boop by Petco. This looks like a benign cyst. I would just monitor it. If you notice it growing larger then have your vet check it. Sometimes cysts do grow and need to be drained. I, personally, would not be worried about it. Hope this helps. Best wishes.

My dog is a 6.5 year old miniature poodle. She’s had this bump for a quite a while now, and has the same on her leg. Should I be concerned? I thought it was a bite, but I checked her and she doesn’t have any fleas or ticks.
Hello, thank you for using Boop by Petco. These bumps are basically benign cysts that are very common in small breed dogs although any dog can get them. I would not be worried and just have your vet check them out at Marie's next check-up. Hope this helps. Best wishes.

Last night I noticed a white bump on Precious's butt. Can you tell me what it looks like to you? Should I be worried?
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. 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!

What could this be? My other dog and him play a lot but this is more of a bump of some sort like a pimple. Doesn’t seem to bother him.
Hello and thank you for reaching out to Boop by Petco. This looks like a wart or possibly a keratin cyst. Both of these are benign growths in the skin. I recommend monitoring this bump over the next 1-2 weeks and if it increases in size or starts to bother Roscoe, it should be examined by a veterinarian. Otherwise, if it stays the same or goes away, I would not be concerned. I hope this is helpful!

I noticed a tiny bump (smaller than a sesame seed) on my dog's prepuce. I can feel it with my fingers under his skin but it's not noticeable on the outside. There are no other symptoms and he's not bothered by it. Should I worry?
This is probably not serious. I recommend feeling it and writing down how big it is every month. I don’t expect it to change but if it does start to grow or becomes painful then please take him in for an exam. I would also point this out to your veterinarian at his yearly exam. From your description this is nothing to be overly concerned about at this time. Thanks for using Boop by Petco to help you care for Oreo.
