In this case, the breeder can correct it by the following methods: 1. Feed the dog first when walking the dog, and then take it out about half an hour after eating; 2. Bring some snacks out to extend the time of walking the dog. Wait until the dog defecates and give the dog a corresponding reward; 3. Or the owner carefully observes the dog's defecation time and takes the dog out when it is almost time to defecate. In addition, everyone is responsible for protecting the environment. I hope all breeders will clean up outside after their dogs defecate.
