My dog has a spreading belly rash. What can I do besides the vet?

Updated On September 23rd, 2025

Pet's info: Dog | Maltese | Male | neutered | 1 year and 5 months old | 12 lbs

My fur baby has had some kind of skin irritation on his upper belly for a couple of weeks. For the last few days, I have been putting on Neosporin (pictures show it with Neosporin on, hence the greasy/dirty looking fur). I think the skin irritation is spreading upwards. He wears a harness on his walks, but most of his belly isn't covered and touches the grass. He has never had any skin issues before. Please don't tell me to go to the vet only for the vet to say they don't know what it is.

Unfortunately, going to the vet is the best option, as you'd need to have the area examined in person and it would be impossible to tell the cause over the internet. Causes of hairloss and irritation can be from a number of things including allergies (potentially to the grass if it's touching, or something used on the grass such as fertilizer) to the environment, food, parasites, metabolic issues, or even skin infections if the area is spreading. Neosporin usually isn't good to put on a dog as it can make them ill if they lick it, and if its spreading even with at-home treatment it likely isn't helping. An Elizabethan (cone) collar can be used to prevent licking and chewing to see if it helps with irritation, and a T-shirt if you suspect the grass is irritating Bamboo's belly may help you rule this out as a cause. However, if it continues, having your vet take a look in person is needed.
