White pimples on my dog's belly: Could it be ringworm or allergies?

That doesn't appear to be ringworm. It could be a bacterial skin infection. Given that he has allergies, this makes bacterial infection more likely. You would need to have this confirmed by your veterinarian. Treatment may be systemic antibiotics, topical treatment or a combination of both. Getting the allergies under control would probably help as well. Discuss allergy testing, hydrolyzed diets, food elimination trials and antihistamine use with your vet.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed.  There are medications such as Apoquel or prednisone which may help with the itch. 

There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. 

Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). 

If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. 

Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

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.

It looks like King may have a mild skin infection. Ringworm is still a possibility even if you don't have any lesions, as it tends to be an opportunistic infection. A bacterial infection is also possible, they can be secondary to allergies. If they are not getting better I'd have him checked out by your vet. He may need a topical or an oral medication to get rid of it completely.

Yes your description could be eventually compatible with ringworm recurrent infection. The other option is an allergic reaction in my opinion. I would consider to have her checked by your veterinarian and tested /and treated) for ringworm.

It could be a small pustule, cyst, or mass. If it persists than you could have your vet take a look at it to determine the cause. Your vet can do a needle aspirate to help diagnose and then determine if treatment is needed.

Hi and thanks for your request. These are epidermal collarettes.; they are 'footprints' of a vesicular or pustular lesion. They are therefore a common lesion type in canine pyoderma, which is a type of superficial skin infection. An allergy could be present, but the signs are solely compatible with an infection. Disinfection can be provided with hibiscrub diluted with water 1:10 twice daily. Make sure to rinse off the solution and leave the skin dry. The signs should resolve in the next 4-5 days, if not a check up will be needed.
