My dog is having this red spot on her belly what to do. Pet's info: Dog | Golden Labrador | Female | 11 months old | 34 lbs

It sounds like she could be suffering from a local reaction or allergy to something, a skin infection, or even bug bites. Usually ticks do not leave this type of mark. I would have your vet look at her. Your vet will be able to help determine the cause and prescribe some antibiotics and allergy meds if needed. Also you can try to bathe her in an oatmeal shampoo from your local pet store to help soothe her. I hope this helps!

They are possibly caused by an infection or a insect bite reaction (that would be basically an allergic reaction). A check up, appropriate disinfection and eventually anti-inflammatory and antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid licking (if any). Parasite treatment should be given through a prescription product ideally. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. Thank you for the photo - I'm sorry to hear that you've found these spots on Tyson! These could possibly be insect bites, such as from a mosquito or fly. They also could be areas of inflammation and/or infection that is either bacterial or fungal in origin. If Tyson does not seem bothered by these spots, I recommend monitoring these spots over the next 24-48 hours for changes in size or if more spots appear. If Tyson seems excessively bothered by these areas and he wants to bite, lick or scratch them, I recommend having him seen by your veterinarian. He/she can examine the spots closely and perform a cytology of the area (looking at cells under the microscope) to look for evidence of infection. I would not put any topical ointments or creams on his skin, as many products intended for humans can be toxic to dog's skin or their intestinal tract (if they lick and consume any product). I recommend keeping this area clean and dry and monitoring for any changes. I hope this is helpful!

Hi, and thanks for your question. This could be due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics).
