My dog has a rash from yard spray. Home treatment or vet visit?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 8 years and 1 month old | 16 lbs

Hello, I just moved to Florida in a gated community where they do all the yard work for you. I noticed last week that they spray the plants with some sort of herbicide. Today I noticed rashes and blisters/pustules near his genitals. When he pees he puts his genitals over those plants. What is the recommended procedure? Do I wash him with antibacterial soap and put hydrocortisone or does he need to take a visit to the vet? Thank you very much.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach!

Sorry Charlie is having this problem. It is likely a contact rash and not usually a terribly threatening issue. I would recommend bathing him in your regular shampoo with a good rinse after. If it is very itchy-Benadryl is generally accepted as safe for dogs and you can find a dosing for this medication online by searching the Merck Veterinary Manual. Triple antibiotic ointment is considered safe topically if your pet is not allowed to ingest any of it as well.

If the rash spreads further or worsens quickly or you notice any other issues or abnormal behaviors besides this rash-generally this then warrants a trip to your vet to stave off symptoms and be treated for a potential reaction.

I hope this helps and that Charlie feels better soon!
