my dog is not toilet train!

Question
Hi!someone just gave me a 2 year old golden retriever 2 weeks ago.and the owner said that it is toilet train. but we found out later that he's toilet training method is different from our's.his way is to let her pee in the toilet.however,we got her a toilet tray for her to pee in.but she still pees around the house.at first i thought she's just not used to the place yet.and to give her time to settle down.but my dad told me that there were a few days in a row that she goes to the tray to pee.and for the 3days, she's been peeing next to the tray instead of on the tray.and just yesterday, while i was playing with her in the morning, i brought her to the tray and she went there and smell then she walked away.after i played with her and was going upstairs (we leave her on the first floor when we go out) to leave the house, i saw her when next to her tray and pee on the floor.and just this morning she pee in the house again.we place the tray in the backyard.but our backyard has no grass or anything.that why we use the tray.we even bought the toilet spray for her but it does not seem to work.what should i do?

Answer
First of all, it's pretty ridiculous to have a healthy adult Golden Retriever pee'ing and pooping inside a home - whoever trained the dog was not doing the dog any favors.  Unfortunately, you are now stuck having to train the dog, as if it were a pup, to do its business outside.  The key is to supervise the dog constantly and when you can't, contain her in a crate or gated area where she will feel that it is like her den and will not soil it.  It can also help for you to feed the dog within the crate or gated area, as they have a natural aversion to eliminating where they eat.  Take her out every couple of hours, reward her for going outside - say the words, so she learns them..."good pee" or "good poop", followed occasionally by a small treat (not every time).
Do NOT scold her for any accidents inside the home (they are your fault anyway if you aren't supervising her), and simply clean them up with an enzymatic cleaner (Petastic, Simple Solution, Nature's Miracle, etc.)

Good luck - you can do it!
