Just wondering if anyone has had a similar problem or has any suggestions... We have lived in our current home for just over a year now with our one border collie, About 2 months ago my mother in law moved in with her 2 small dogs (yorkie poo and shihtzu poodle) these dogs have very very strong smelling pee, and they pee on everything... i dont know what to do about it ive tried hosing my lawn and fence off, it rains alot here too i have even removed everything in my back yard, all toys, deco, planters etc. its gotten to the point where i dont even play in the back yard with my daughter and dips in the hot tub are unpleasent due to the smell of my back yard anyone have any ideas of getting rid of the smell? i've wondered if its due to the food they are on and have tried to educate my mother in law about better diets and offered to buy her new food... she isn't willing to switch food
