My dog has sudden red bumps like mosquito bites. How can I treat them?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 10 months and 10 days old | 66 lbs

Hi, my dog cass got red bumps all over him all of the sudden. He didn't get in to anything that i know of. They look like a bunch of mosquito bites and they dont seem to bother him. I know its not bugs beacause he is treated with vectra 3D monthly and interceptor plus. I dont want to have to bring him to the vet either unless i have to because we just finished paying a big vet bill. I dont know how this happened or what i can do to fix it.

Hi there and thank you for using Pet Coach to address your concern. Without pictures it is difficult to say what the red bumps are. I would presume a possible allergic reaction / skin infection. My suggestion would be to start the following, all of which can be found online: 1. Malacetic conditioning spray (spray to affected area 2-3 times per day until resolved is the typical recommendation) 2. Duoxo PS Calm shampoo and bathe twice weekly until resolved is what most dermatologists would recommend Benadryl has been used on cases like this. The typical recommended safe dose for Benadryl is 1mg per 1lb of body weight every 12 hours. I hope this helps. If the bumps to not resolve or if they worsen I would seek veterinary care. Please let me know if you have any other questions or concerns. I am also available for consultation if needed.
