Removing dog waste

I am usually with my dogs while they are outside. So when they do poop I usually pick it up with a doggy bag and throw it in our trash bin for the garbage men to pick it up. When I just had my Malamute I would go out there every other day and pick up the poop but once we got our german shepherd is when I started using the doggy bags. My german shepherd likes to eat his poop after he is done and then we would go and eat my malamute's as well. So that is why I have to hang outside with them to pick up the poop. Otherwise he would have a snack after he poops every time.
