My dog has non-itchy bumps on his skin. What could it be?

Lesions like those in the pictures can be caused by bacterial, parasitic or fungal infection, dietary or environmental allergies or sensitivities, immune system disorders, or a combination of the above. In dogs like yours with hair loss and itchiness, one common cause can be infection by mites that can live in the hair follicles and lead to hair loss, and secondary bacterial and fungal infections that can develop. I recommend making an appointment to have your dog seen by your veterinarian to help determine the cause of the hair loss as soon as you can. The vet will likely want to look at a sample from the area (taken by a procedure known as a skin scraping) and examined under the microscope to determine what kind(s) of infection may be present and to figure out what medication is appropriate for treatment. I hope that helps!

It could just be a ruptured cyst or some type of mass. Your vet can do a needle aspirate to diagnose the exact cause and determine if there is anything to worry about. If needed, your vet could remove the bumps. If the lesions appear infected then he may need an antibiotic to treat. Since he seems itch, you could bathe him with a medicated dog shampoo like Epi-soothe and see if that helps.

I doesn't look like an insect bite. It could be a small wart or other mass. The only way to know for sure would be to have it examined by a vet and have a sample evaluated under the microscope. There is a type of tumor called a Mast Cell Tumor that can cause itching.

This does not sound like a normal thing to happen in dogs, and I recommend that Binky see a vet for her skin issue. Your vet may do a skin scrape to look for mites, skin cytology to look for bacteria or yeast under a microscope, or bacterial or fungal cultures may be needed. Possible causes for bumps include fleas, mange, lice, infections (bacterial or yeast), ringworm, allergies, among others. I would recommend that Binky be on year-round flea prevention. While you await for your appointment, you can try a medicated shampoo like Dechra MalAcetic Ultra Shampoo, but be careful not to get it into her eyes. Also, think of any changes that have happened in the last few weeks, like changes in food, treats, medications, supplements, or household cleaners that could have had an effect on her skin.

Hello. This looks pretty typical for an allergic dermatitis that has lead to a skin infection. Ideally, this should be addressed by your veterinarian. They can discuss possible causes (food allergy, contact allergy, flea allergy, etc) and prescribe medications which may include antibiotics for the raised lesions and allergy therapies.

That is an understandable concern. It appears he has a very bad case of folliculitis, which can be caused by several things including a Demodexx mite infestation, a contact allergy, environmental allergy or flea allergy. He needs to first go on a good flea preventative (Nexgard, Bravecto, etc) and then have a skin scrape/cytology done to look for possible mites. He definitely needs a short course of antibiotics to treat for his current skin infection and then medication depending on the results of his skin scrape/cytology. The vet should be able to get him on the right track if the skin testing is done. I hope this helps and best wishes with Trump moving forward. I hope his skin problems resolve very soon.

Judging from the pictures, this could be a skin infection, reaction or skin tumors. I would recommend having a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. There is different treatment for these different causes and it would be best to have the condition confirmed in order for Vader to receive the most appropriate treatment. 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!
