I have a 3.5 year old male miniature schnauzer and he insists on peeing on my daughters play equipment. I don't care if he pees on the house or shed or clothesline pole or plants but I just want him to stay away from the slide in particular, as it pools at the bottom and goes sticky and brown on hot days (vomit!). I read somewhere that amonia can work if you spray it where you don't want them to pee but it went on to say it can make it more appealing to some dogs (plus I don't like the idea of my daughters skin coming into contact with it)! It also suggested vinegar but that didn't make a difference.
Can anyone suggest something to deter him from peeing in certain areas? Something that won't harm my toddler if she comes in contact with it.
