We put our doggy bags in the garbage, and it is against bylaws. In the city I live in, you can be fined for disposing of animal waste in city garbages, but I live in a multi-family complex so they would fine the strata. Here, we're supposed to take animal waste to the landfill. Can't be bothered.
We use eco-friendly bags that get thrown in our apartment complex's dumpster. I don't think you are breaking any laws by throwing them in your own trash can
Since they go on puppy pads it goes down the toilet. Because of this they seem to think they're not allowed to go the toilet outside, which is fine by me because I'd rather I didn't have to deal with poop scooping outside or having to leave pee around.
My dogs go outside to potty, few times a week i just clean up there poo area and fling it into a section of the woods we dont go and over time it just disolves, we have alot of woods on our property so i can fling it just about anywhere. LOL!!
