Human yeast treatment on my dog's paws

Dear Aunt Vadge,

I have a dog who gets moderate to severe yeast infections on her paws, and she’s constantly licking and chewing them. The worst part is she smells like sour popcorn, and it’s driving me nuts. Nothing has worked, and even the vets haven’t been helpful.

If I used your lactulose product on her paws, would that help? In my head I’m thinking yeast is yeast.

Hey there,

Poor pup – that sour-popcorn smell is the classic signature of yeast overgrowth. We’re a human vaginal-health resource rather than a vet, so anything here is ‘run it past your vet first’, especially as she licks her paws. But yeast is yeast in a lot of ways, and plenty of what works for us is worth considering for her too. Here’s what genuinely helps.

Starve the yeast and dry it out

Keep the paws bone dry. Yeast loves warm and damp, so dry thoroughly between the toes after every walk, wash or wet grass – this alone makes a real difference.
Cut the sugars and starches. Yeast feeds on sugar, and many dogs with chronic paw yeast improve on a lower-carbohydrate diet. Worth trialling with your vet.
A diluted apple cider vinegar paw soak is a gentle, popular home measure – it makes the skin less yeast-friendly. Dilute well and never use it on raw or broken skin.

Antifungals

The same plant antifungals we use for human yeast – like horopito – act against yeast generally, and there are antifungal washes and wipes made specifically for dogs (your vet can point you to a chlorhexidine/miconazole one). Our own products are formulated for human bodies, not pets, and because she licks her paws, please don’t apply any oil-based or essential-oil blend without checking with your vet, as a few that are fine for us don’t agree with dogs.

And find the why

Recurrent paw yeast (often Malassezia) is usually a sign of an underlying allergy or skin issue – so the lasting fix is finding that. If your regular vet isn’t cracking it, ask for a referral to a veterinary dermatologist, or find a holistic/integrative vet who’ll look at diet, allergies and environment too.
