I first received my pup head last sept . I was very easy to get My Girls to use it . I just placed wee wee pads aropund it for the first few weeks then i slowly started to remove the pads now they just use the head . The only down side is the cleanimg you have to clean it every week of it begens to smell really bad ... I highly reccommend the petapotty which is natural sod instead of astro turf.
