I can't figure out why, because nothing has really changed but my two boston terriers (actually I don't know if it is both of them or just one but they live in the same area when we aren't home) keep peeing BESIDE the mat! They have been pee pad trained almost since they got home, it didn't take them long, but now at almost one (they'll be one next week) they are suddenly peeing beside it. Not even like accidents while running to it..no purposely beside it. Nothing in our life that I can think of has changed to cause this. I've done all the stain remover smell remover stuff and still they pee beside the pad. Can anyone give me a hint as to why this might be happenning and how to stop it? I just got up because my husband came home to find out they peed ON TOP of their dog create (they can get up top and lay on it (there is padding)). WHY? WHY? WHY? Can anyone tell me why...they've been trained for like 8 months no problems!
