Dog's sensitive stomach, smelly poop/gas. How to fix without changing food?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 6 months and 10 days old

I put my dog on Hills dry food instead of Purina because he has a really sensitive stomach but his poo smells absolutely disgusting but he's stopped having loose stools like he was having while on the other food. I don't want to change foods again as I don't want to upset his stomach, is there anything I can give him to stop it from smelling so bad? His gas also smells awful

If he is a young dog it is possible that he has a mild food allergy or an easily upset stomach (sometimes this is irritable bowl syndrome). Typically strong smelling gas in from the diet. I think slowly switching Ziggys food to maybe a different protein source of purina would help calm down or stop the gas. However, if you want to try an over the counter probiotic every day in the food and see if helping the good bacteria grow improved the gas. Do not forget to have a fecal checked for parasites just incase! hope that helps

    It is normal for some dogs to be more gassy than others. You could try to add in a probiotic daily to see if this helps. Also if he is generally just smelly sometimes, I would have your vet do a thorough exam on him. Smell can come from ear infections, the mouth, the anal glands, skin infections or even around their prepuce. Your vet should be able localized the smell and help you solve it. Sometimes they just need a thorough bath. I hope this helps.
