Hello. I have an adult dog (3 years), Miniature Schnauzer. She goes outside to do everything, but we are going to move to an apartment and I want her to do her things in an specific place inside the apt. I tried once in other apt, and she waited 24 hours, and at last she did it. But I suffer a lot because I think its not good for her bladder or her intestines. Please, tell me how to do it and if she wait, is not to bad for her?
