Dog Waste Bags for Dogs - 200 Count Biodegradable Poop Bags for Dog Walking, Hiking & Travel - Eco-Friendly Pet Cleanup Supplies

These are the best bags I've found. I have two greyhounds (and sometimes a third foster) so we go through a lot of "litter" bags! These bags are a good size and they hold up well. They rarely, if ever, rip where they aren't supposed to. I just keep the open box by the dog leashes, pull a few out and we are on our way.The cost usually ends up to be around $0.07 per bag. I generally buy them from KV Supply and, as someone else mentioned, even with the $5.00 handling fee (if you spend less than $50) they are still a very good value.Don't be fooled by imitators though! I purchased the imitation brand once (box looks very similar but does not say Dogipot) - they were more 'plastic-y' feeling and almost every bag was open at both ends. Dogipot is the way to go.
