can someone please explain to me how dogs are attracted to using them? I am thinking of getting some for my pup at night as she pees in her crate and sleeps in it. Not to bore everyone since I have posted already but basically she pees before we can get her out of the crate as she gets nervous so I have her sleeping on a rubber mat with towels next to my bed but she just pees in her sleep. (I think...I never hear her move) so I am wondering if a pee pad would help and if she would even realize it was there to use.
