Does it really make a difference which method is used by an owner for whatever reason? If peepads work great...if using the outdoors works great...if a combination of both is best...great. Just seems that too many have an opinion on what works for others. I use pee pads for Bella because it works for me...I do not need to worry should I not get home on time because of traffic, meetings, etc. I once was caught in a snowstorm when I had my Bichon, Emma and was stranded for 48 hours...my poor dog had been crated that entire time and was covered in her own mess as a result and an emotional wreck for weeks from the experience. With Bella she can get up in the middle of the night if she needs too and I don't need to get dressed and walk out with her. I find that it fits my lifestyle and it works for both of us. When I have traveled with her both in hotels and resorts this method has been very adaptable to both with excellent results. So again my feelings are that owners should use whichever method works for them....
