Dog Diapers

I use diapers constantly with Heidi. For dogs who have lost bladder control — which is common with IVDD and DM — diapers are not optional equipment. They’re infrastructure. You’ll go through a lot of them, so the practical questions matter: how well they fit, how absorbent they are, and whether you’re buying disposable or reusable.

Sizing matters more than brand. Dog diapers are sized by waist circumference, and a diaper that doesn’t seal well at the legs and waist is worse than useless — it leaks, creates wet skin, and causes the exact rashes and sores you’re trying to prevent. Measure your dog’s waist before ordering and refer to the manufacturer’s chart, not generic size names.

Disposable versus reusable is a genuine tradeoff. Disposables are more convenient for daytime and any time you need to change frequently — and with an incontinent dog, you’re changing often. Reusable diapers are more economical for long-term use, but they require a washing routine and you’ll need enough in rotation to have clean ones available. Many caregivers use disposables for daytime and reusables overnight.

Absorbency varies significantly by brand. For urinary incontinence, standard absorbency is usually sufficient if you’re changing every few hours. For dogs who are also fecally incontinent, look for higher-absorbency options and change as soon as possible after a bowel movement — fecal contact with skin breaks it down quickly.

One thing I’ve found essential: line the leg holes and waist band with Vaseline before putting the diaper on. The edges of diapers rub on skin with every movement, and without a barrier, you’ll see redness and irritation within days. Vaseline prevents that friction. I also pair diapers with wipes for cleaning during each change and cranberry chews to reduce UTI risk from moisture near the urinary opening.
