I don’t actually have a dog and bought these based on the good reviews. I wanted something handy I could keep next to the litter trays that was strong enough for when I do a quick clean. I was not disappointed.Each bag was able to take a days worth of clumped clay litter wee from two small cats, and I was still able to tie it. Note there are no tie handles. If I’ve left the litter a bit too long I’ll use 2 bags. And they hold strong when they go into my larger wheelie bin. No more disgusting torn dirty litter bags. The bonus is that they do have a nice smell too and thick enough that there is no escaped poop smell.The only downside is that for litter use it would have been nice to have tie handles but as they weren’t actually made for that purpose it would be unfair to judge them that way. They do certainly fit the whole of the hand and occasionally I’ll use them that way to pick up smelly poos that my dopey cat couldn’t quite figure out how to cover.Overall great for using as waste cat litter bags and if anything, proves their strength!
