Why does my dog have a painful purple lump with redness on her belly?

Thanks for using Petco Pet Education Center, formerly Petcoach! 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 him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

Hello. I think that Hershey just had a hair follicle get infected, very similar as to what can happen with a bad acne spot. You can just clean this daily with a skin antiseptic like Hibiclens ( available at all pharmacies ) & dab a little triple antibiotic on the area. It should heal up just fine.

The picture you posted does not look like a pimple, so I am worried that it is actually a mass. Anytime a new mass is noticed, I always recommend having it evaluated to see what it is and if anything needs to be done about it. Unfortunately, we often can't tell anything about a mass by just looking at it. Your vet can perform a simple test called a fine needle aspirate where they use a small needle to collect some cells from the mass, then look at them under the microscope. They may even need to send the cells to the lab for a pathologist to examine them, so we know what the mass is. If it is benign, you might not need to do anything about the mass at all, but if they see cells that worry them, they might recommend removing the mass. If the area is infected, then your veterinarian may prescribe oral or injectible antibiotics to resolve it. Good luck! I hope that was helpful.

This appears to be what's known as a serous cyst. These are often caused by some sort of trauma to the skin; like a pinch or bite. They are usually benign (will not cause a problem) and will go away on their own in two weeks or so. It's possible for it to get infected, so watch for signs of increased redness, pus and an increase in size as a sign that it is getting infected. If you notice this, then she will need to go to the vet for treatment. I hope that helps and Nahla gets better soon.

In the picture, it appears that the affected skin is bumpy and then there is quite a bit of redness around the edge. It’s possible that it could be a wart-like growth, but because of the amount of inflammation (causing the redness) going on, I would recommend taking Mac to the vet for a closer look. The vet will also look closely at all of Mac’s other skin (and mouth and other mucous membranes) to see if there are any other affected areas. They may be able to diagnose or have a better guess as to what’s going on, and discuss treatment options if any need to happen. Until he sees the vet, it would be helpful to have him wear an e-collar/cone so he can’t lick the area anymore. Licking will increase the inflammation and can skew how the vet evaluates the area.

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear Candy has a bump. I do recommend all new lumps or bumps be evaluated by a veterinarian to determine if they are potentially malignant (cancerous) or not. Depending on what it may be will determine what can be done for it. Good luck!

That is certainly in the area where the inguinal lymph node lies. The red area there looks like a possible tick bite dermatitis. I would recommend starting with antihistamines and let your vet take a look at this area. If your pet also has a fever, then a course of antibiotics should be considered in case there is an infectious component here. A tick titer may also be considered if your pet is exposed to ticks and not on prevention. I hope that your pet's skin issue resolves soon! Best wishes and take care.
