“I stopped sizing up. These extenders gave my pup the snug, gap-free fit we needed and the red marks disappeared overnight”

According to Katrina P.

“Post-surgery swelling made fit tricky. Extendrs® bought us comfort and leak control without rebuying a whole new set”

5-Pack Extendrs

Our dog is over 50 pounds and incontinent. Initially, we were unable to find belly wraps (washable or disposable) that were large enough. The Extendrs make all the difference with larger dogs. They offer just that extra needed extension to seal the belly wraps comfortably. The 5-Pack, along with the one extendr in a 3-pack of washable belly wraps, provides ample supplies for regular changes.

Belly bands, extenders and blankets

I have bought all three of these products and they are amazing. The waterproof blankets are great and so soft but after washing they aren’t soft but that could be user error I sure. I didn’t not wash on gentle. Ugh! I have all three sizes too. The belly bands are fabulous. They hold so much liquid but make sure your lil guy private is tucked in it. Haha The emails that are sent are fabulous and make me laugh everytime. The pet-tergent is also fabulous and I use all the time. Thank you for having fabulous products and bringing smiles to all our faces including the furbabies.
