My favorite thing are those who say that training outdoors & the pee pad will only confuse the dog. All I can say to those people is that the dog is smarter then they are. I do believe that some dogs prefer one to the other , but I have always trained for both. I have had many, many dogs in my home of all ages as I rescue only the sick & injured & never had a problem with potty training to both outdoors & pee pads. I agree with the others who have said it's nicer as far as bad wether as well. I would much rather they feel comfortable going indoors when I need to leave for several hours then risk them holding if for so long, risking UTI.
Not to mention how uncomfortable it is to hold it for 8 + hrs. Next time someone gives you a hard time about it, ask them if they can hold their pee for 8 + hrs.
I know I can't.
