FAQs
Monty’s Bags break down fully in 3–6 months, unlike plastic bags which can take hundreds of years (or never) to decompose. A simple switch that makes a big environmental impact.
Our bags are made from cornstarch and bio-based plant materials (PLA + PBAT) and come in our signature creamy yellow colour—not the typical “green compostable bag.” They’re strong, leak-resistant, and larger (9 × 13") than many standard bags.
Yes! Thick, tough, and reliable. Designed to handle all breeds—from small pups to big dogs—without rips or leaks.
Yes. We even offer Triples Rolls (45 bags per roll) for fewer roll changes and better value—perfect for multi-poopers, multi-dog homes, and busy dog walkers.
Absolutely. We support dog walkers, pet boutiques, groomers, commercial properties, condos, and municipalities with wholesale and bulk order options. Contact us to learn more.

Excellent product and service
As a multi-pooper owner I go through a lot of bags over a year, and these do the job well, aren't plastic and available in bulk. All good things.

Great Bags
Good quality bags that are quite thick and don't tear. Nice to know we're not throwing out plastic anymore. Personalized note was a very nice touch and we're supporting a Canadian company.

Highly recommended
We changed from Earths Own compostable bags as these were cheaper (especially with the BOGO offer) and from a local BC seller. The triple packs and dispenser are great as have to replace less often and easy to load. Only downside is the bags are slightly harder to open but this is very minor issue for a compostable bag. Will continue to use, thank you!

Great product!
I have a 55 lb Shepsky and these bags work great! Very happy with the size and the service: when we received our first shipment, it included some fun extras, much appreciated! Also enjoyed the colourful tape outside the box. ;)

This is the second order and I love the bags, especially the 45 roll ones. I also love that they are environmentally friendly.

The best poo-bags ever!
These are the best poo-bags. Not one bit of plastic in them. I love the colour. I'm so sick of green bags claiming to be friendly for the environment. Go Cornstarch Go! I've handed these out to friends to convert them to Monty's.

Everyday Favourite!
Our sweet girl absolutely loves this mat — it gets used almost every day. The honeycomb sections are great for berries or chopped veggies. We have just purchased a second one to alternate throughout the week!
