My dog has a blister on her armpit. Should I worry or use Neosporin?

Did you mean to have a picture attached to your question? If so, unfortunately there was not one attached. Puppies often get “pimples/pustules. This is usually a skin infection called puppy pyoderma. However, other problems such as a bug bite are possible as well. A Small amount of neosporin is unlikely to cause any harm at this time. Most mild Cases of pyoderma will resolve on their own or with a medicated shampo. However more significant cases need antibiotic therapy. I would recommend that you monitor the area close for any change or other pustules to appear. If it doesn’t resolve in the next few days then I would encourage you to have her evaluated by your veterinarian. Best of luck and thank you for using Pet Coach.

It sounds like he has a bacterial skin infection (puppy pyoderma). You could bathe him with a medicated dog shampoo but he may need an antibiotic and possibly a corticosteroid to treat the problem. Have your vet take a look at him to determine the best way to treat his problem.

Thanks for using Petco Pet Education Center, formerly Petcoach! 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 not sure if there was supposed to be a photograph attached to your post, but that would be helpful. Red raised masses can be something like infection or an ingrown hair. They can also be more indicative of a skin tumor. Of the skin tumors, most are benign but there is one called a mast cell tumor which is cancerous and needs to be removed quickly. When in doubt, I always recommend to have any type of skin mass examined by the veterinarian. Sometimes they can tell what it is based on exam. But just like with humans, not all skin tumors can be identified just by looking. The doctor may need to aspirate some of the cells to look under the microscope. That is the only way to accurately know what kind of tumor it is. I always recommend to play it safe with something like this! I hope this is helpful and please feel free to post any additional questions.

Thanks for using Petco Pet Education Center, formerly Petcoach! I think that this looks severe enough that it warrants a veterinary evaluation to shave and clean the area appropriately and also start him on antibiotics to treat a possible infection. They can assess how it looks on a close examination and treat it accordingly. Good luck and have a great day!

Hi Maisie! If there is some pus coming out of it, this lump could be an abscess on Mika. It could also be due to a bacterial skin infection. I would have Mika seen by a vet tomorrow or first thing on Monday to have the lump examined and diagnosed. Once a diagnosis is found, the vet can discuss treatment with you.

That should be seen by your vet for exam and identification. As small as it is, it may be relatively simple to remove by your vet. Until you can get her seen, keep it lightly covered to keep it clean. Your vet will do a physical eam on her, possibly some labwork, like an impression smear, where they press a clean slide against the growth to be eamined under the microscope. Based on these results, your vet will be better able to tell you what is going on and how best to treat it.
