What causes pimple-like spots on puppy stomachs in hot, humid weather?

The bald spots and pimples may indicate minor infection or may be a symptom of a broader underlying condition. Skin problems can have a variety of causes, sometimes more than one. It is important to have the condition addressed by your veterinarian to determine if there is a medical cause for your pet’s skin issues and treat accordingly. Young dogs can get skin infections, commonly referred to as 'puppy pyoderma'. This usually occurs on the belly and inside the hind legs. This type of infection usually resolves without treatment as the puppy gets older. [*Staph* infections](https://www.petcoach.co/dog/condition/staphylococcal-pyoderma-1/) are common in dogs of all ages and may requires antibiotic therapy to treat. In pets of all ages, [fleas](https://www.petcoach.co/dog/condition/flea-allergy/), [food allergies](https://www.petcoach.co/dog/condition/food-allergies/) and [environmental allergies](https://www.petcoach.co/article/food-allergies-vs-environmental-allergies-whats-the-difference) (contact or inhaled) can be a cause. Any one of these may not be enough to trigger the breakouts, depending on how sensitive your pet is, but a combination can be enough to start the itch-scratch cycle. Finding out the cause and eliminating it is the best course of action. With flea allergies, if your pet is sensitive enough, a single bite can cause them to break out scratch enough to tear their skin or cause a [hot spot](https://www.petcoach.co/dog/condition/hot-spots/). Diagnosing the cause of allergies may require [allergy testing](https://www.petcoach.co/article/allergy-testing-immunotherapy-in-dogs) and [food elimination trials](https://www.petcoach.co/article/food-trials-for-allergies-in-pets-what-to-expect). [Check for fleas](https://www.petcoach.co/article/how-to-check-your-pet-for-fleas-and-ticks) with a flea comb. Look for fleas and/or tiny black granules, like coarse black pepper. This is flea feces, consisting of digested, dried blood. You may find tiny white particles, like salt, which are the flea eggs. Applying a good topical monthly flea treatment and aggressively treating your house and yard will help break the flea life cycle. If you use plastic bowls, this is a possible cause for hair loss, though this tends to be on the chin, where their skin touches the bowl while they eat. If you suspect this to be the culprit, try changing the bowls to glass, metal or ceramic.

Hill's Science Diet offers some non-prescription options for sensitive skin as well as [prescription hypoallergenic foods](https://www.petco.com/shop/en/petcostore/category/dog/dog-food/prescription-dog-food-and-treats) for more severe cases.

Your vet can recommend a specific diet that will help.

It could either be pustules or papules which are typically a sign of mild allergies. I would recommend monitoring these areas for now if they are just localized to 1-2 areas on the body because they can resolve on their own. However if they start to spread or bother your pet (excessive licking, scratching, whining), then it is best treated with anti-histamines/steroids through your veterinarian. Allergies can be to just about anything, including food, chemicals, and other things in the environment.

Hi and thanks for visiting Petco Pet Education Center, formerly Petcoach. Pimples on the body of a young puppy are likely caused by an acute allergic reaction to something he came into contact with. There is also the possibility of him having a condition called puppy strangles, which will cause spread of rather large pimples to his face, ears and neck area, and these pimples can then rupture causing discomfort for your pet. It is hard to say for sure which is likely here without a good visual of the area. I recommend considering reposting your question with a photo for a more tailored answer. If the pimples are small however, they are likely just an allergic reaction and may go away on their own, especially if there are just a few. I would recommend monitoring these to see if they get worse. I hope this helps and best of luck with your puppy Logan. Take care.

Skin lesions like these can be caused by bacterial, parasitic or fungal infection, dietary or environmental allergies or sensitivities, immune system disorders, or a combination of the above. Sometimes puppies like Palmer can get a type of “puppy acne” along the belly as well. If the lesions do not start to go away in the next week, or if they start getting worse, I recommend making an appointment to have Palmer seen by your veterinarian to help determine the cause of the bumps you’ve noticed and to make sure they are treated appropriately. The vet will likely want to look at a sample from the area under the microscope to determine if there is an infection and to figure out what medication is appropriate for treatment.

It's hard to say without a picture. Puppies can often get small, pimple-like spots on their belly. They are related to changing hormones and go away on their own. To be sure, though, PIplo should be examined by a vet.

He may have a condition called puppy pyoderma that is roughly equivalent to acne in humans. They usually will outgrow it over time but some get it worse than others and need some medications and possibly therapeutic baths to help them get over it. I suggest getting him seen by your vet to make sure that's what is going on or if he has some other kind of skin condition that may require different treatment. Your vet will do an exam, possibly collect some cells for examination under the microscope and based on these result will be better able to tell you what is going on and how best to treat it.

This is called puppy pyoderma. It’s a mild skin infection that puppies often get. You can bathe the area with anti bacterial shampoo every few days and that should clear it up. If it is getting worse or the puppies seem sick then bring them in for a exam and treatment. They may need oral antibiotics. Also make sure the bedding is soft and dry.
