I used a spray like this when puppy's goldfish memory forgot what going outside meant for a few days. This was during his pre-vaccination period when one tends to look to alleviate the stress of toilet training by trying all the quick fixes.
The spray contains pheremones - sorry can't remember the name. It worked the first couple of sprays in that there was an instant wee but after that it was no use at all and I went back to nature and perseverance.
I am not too keen on it- it honked worse than the wee and my limited grass area was totally wrecked by it [the wee of couse did some damage but the spray was by far the worse culprit].
The smell also lingered - especially in the heat of last summer.
Incidentally the puppy training pads were also a waste of money but I think I knew that at the time - it is so tempting to buy up everything for the Bubs at the pet shop but I am now turning into my own Mum and being much more sensible.
