Luna, 11 years old
After 5 nights of our puppy barking for the majority of the night in her crate in the kitchen, we felt as though we were never going to crack the crate training. Purchased this on Tuesday evening, there was less barking which gradually has got less and less as the days go on. We are now just over a week on and last night we had a sound sleep from 10.30 until 6.30am. I'm not saying that we owe it all to the plug in but I believe that it has definitely helped her settle in quicker. She often goes and sniffs it under the table at the plug in diffuser, so proves that it must be giving something off. I will continue to buy the refills until she is 1 years old.
