Absolutely. In fact they wear collars for doggie doors to run outside anytime they want. The problems seems to be they associate outdoors for play only. I want them to potty first and them play but right now playing is first priorityfor them. They forget to potty and them remember apparently as soon as they come back in. I try to emphasize to use potty first, but we apparently that second to them right now. Believe me they sleep from being tired out several times a day |
