This appears to be a possible pustule (infected small pocket underneath the skin). If just one of these is present and it isn't causing any discomfort, then I would suggest monitoring the area to see if it resolves on its own. You can gently clean the area with a mild soap (ie Dove) and warm water and placing a very thin layer of Neosporin to the bump to see if it goes away. However if it starts to spread or does not resolve within a week or two then a vet visit is needed to get Louie on a short course of antibiotics to get this to heal well. Best wishes and take care and I hope this resolved soon.

    Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on the picture you provided, I suspect this could be an area of the skin that has developed an infection or these are insect bites (ants, etc.). I would recommend using Sentry Topical Wound Ointment which can be found at Petco and apply this twice daily until resolved. If the bumps continue to spread, worsen or do not resolve, I would recommend having Jax examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further. Please take the time to mark this question as helpful or not as it helps us to improve on the quality of our answers to other pet owners. Thank you kindly!

My 3 year old Jack Russel-Yorkie, Lucas, has a big white lump on his stomach. I just noticed it today. It doesn’t seem to be hurting or bothering him, but I’m concerned. Should I try to pop it? And is there a way to fix it without going to the vet?
Hello. Lucas has a small infected plaque, but nothing to be overly concerned about. Do not pop this, but do pick up a skin antiseptic called Hibiclens ( available at all pharmacies ) & gently clean the area 2-3 times a day. If it pops on its own, just continue to clean the skin until it heals. Lucas should be just fine. Thanks for contacting Boop by Petco.

What does it mean when you're dog has a white bump on her belly
A white bump could be indicative of an infection (like a pustule) or could be a mass under the skin, a cyst, or some type of wart/skin tag. If you could post a picture of the bump you are worried about it would help us better understand what is going on.

Skipper developed a soft lump on his rt side. Very quick development. No obvious pain or discomfort
Has he been licking at it? Can you identify a wound on it? It may be an abscess (localized infection) under the skin, as thise can show up very quickly. You can shave the hair over the top and clean it with dilute Betadine (available at any pharmacy - use water to dilute it so it looks like tea). Put an ecollar (cone) on him to prevent him from biting or chewing on it, and make an appointment with your vet as soon as you can—but it’s not something you need to see an emergency vet for as long as it’s not seeming painful and he’s eating and acting normally. Other possible causes would be some type of tumor (though less likely with his age), or a fluid accumulation called a seroma. Your vet may Do a fine needle aspirate (poke the bump with a needle and then look at cells under the microscope) to see what it is and then know how best to treat it. Thank you for asking Boop by Petco!

My dog has a bump on her back. She has a lymphoma on her booty 6 months ago but it looked nothing this. Please help.
This could be an infected cyst, a deep pustule which is essentially a zit or some other type of skin tumor. I recommend keeping it clean and dry, monitoring it for any change in size, redness, discharge or pain. You could try applying a medicated pet shampoo daily and monitoring it afterwards. However if it becomes enlarged, red, painful or more appear or it does not go away after a couple days then Bellybutton needs to be examined by her veterinarian.

This looks like a little pimple or abscess. This is not a serious concern but should be examined by your veterinarian who may elect to lance it or just wait until it bursts by itself. Your vet may want to prescribe an antibiotic shampoo to keep further pus-filled "pimples" from appearing.

Hello, what it can be? It's behind the neck, on the back.
This may be a pimple (little abscess), cyst or a tumor. . An abscess can usually be treated with antibiotics and/or be lanced, and a cyst can be evacuated. Your vet may want to do a fine needle aspirate (he takes some material from the bump with a needle and then looks at it under the microscope) to determine whether the mass is concerning. This may also just be a wart. You can observe this for a week or two and if it does not grow, just keep an eye on it. If it grows, take your dog to your vet for an exam.

My 9 week old Bernedoodle (male) has what looks like a pimple on his tummy? Is it a mosquito bite? Is this just something we should monitor or should we take him in?
Hello, Thanks for the good picture. I agree that it does look like a solitary pimple, very well could be from an insect sting initially. I would just monitor this for now. If it spreads into many pimples, a larger sore, or an itchy rash, those would be reasons to have him seen by his veterinarian to ensure he doesn't have a skin infection that requires treatment. You can use a warm compress with saline or epsom salt water on the area for a few minutes twice per day. Otherwise, don't apply any ointments and just let it stay dry and open to air. I hope this helps. Thanks for using Boop by Petco.

As I was petting her yesterday I noticed a pimple like bump on her left side. Could this just be a bug bite? Or something more serious? Should I put anything on it?
Thanks for using Boop by Petco! This could be a benign or malignant growth. This could also be a bug bite or site of infection. 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. You can try using a thin film of triple antibiotic in case it is truly just an infection or bug bite. Good luck and have a good day!

My dog is having this small thing on her side of stomach area.is it dangerous?what is it?why is it red?
This is likely to be a small ''pimple''. It is very likely to be completely benign and only mild disinfection may be resolutive. Disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any licking (if any). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hello my dog got this bump next to his eye .Is this a pimple or something worse?Thanks for the help.
It could be something like a pimple but it could also be some sort of a skin mass. Pets can get many types of lumps and bumps. Most of these tumors will be benign but some will be malignant and you can't tell by looks. Here is a helpful link discussing the various types of skin masses in general: https://www.petcoach.co/article/lumps-and-bumps-on-your-pet/ You may apply a warm (not hot), compress the the area for the next few days. This can help if it is a pimple. If the mass is still there in two weeks, I recommend to have it checked out to be safe. The doctor may recommend to aspirate the mass to examine the cells under a microscope. That is one of the best ways to know what it is and if further action is needed. Hopefully it's nothing serious.
