I have a 9 week old puppy who is very much going through teething and is very anxious and upset when it comes to bed time, we’ve had him just over a week now he doesn’t like being on his own, with alot of sleepless nights, he would cry and bark ALL night. So this package came Saturday. I’m on my 3rd night of using this product. I use the plug in, in my lounge in the evening and then half hour before bedtime I’ll plug it in the kitchen where my pup sleeps, I’ll spray his bed, & some of his cuddly toys with this too about 15 minutes before bed for them to dry a little. And just before putting him to bed I’ll use the wipe for around his mouth, chest area, have a little cuddle with him to set him to sleep. I also use teething gel too. He’ll cry for 5 minutes and then goes to sleep!!! Which is amazing for him. He will wake at 3am which I dont mind. The smell is not to everyone’s cup of tea but it’s not terrible. But I think if your a fur mum or dad, you’ll happily ignore the smell just to have some sleep. So far so good. Definitely worth a try.
