Why does my puppy have itchy bumps after being outside at night?

Updated On September 23rd, 2025

Pet's info: Dog | Bulldog | Female | unspayed | 4 months and 15 days old | 32 lbs

Hi..my 4.5 month old Pit bull has bumps on her hind legs and sides, she plays outside off and on during the day and at night. It seems that she's more irritated after going out at night, I'm wondering if mosquitoes are biting her. I clean areas 2 times daily with warm water and run coconut oil on her, some are drying up some arent and I give her Benadryl. She's had all her shots, took her to get but she said it was teams from her biting or scratching. She smells like urine. Any help is appreciat

This is probably 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 (advocate or advantage), 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). 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.
