Within a few minutes of plugging this in in my kitchen (where the dogs sleep) I noticed an improvement in my anxious toy poodle’s behaviour. He was weeing in the kitchen when left with his companion dog (separation anxiety). I got so fed up I bought calming drops, used adaptil spray on their bed and even bought a dog nappy… It turns out the only thing I needed was this amazing plug in! Since using it he hasn’t done any wees indoors and has been very relaxed. He still complains when I go out but he doesn’t wee so the product seems to be working! At first I kept his dog nappy on him as I didn’t know if the plug in would work but there was no wee in the nappy on inspection later. A few days later I tried him without a nappy and he didn’t wee! The plug in is the only thing that has worked: the drops seemed to do nothing, the adaptil spray helped but he still weed in the kitchen. I’ll keep the nappies aside as he’s nearly 9 so may need them when he’s older. But I will be using this plug in every day now. We have two dogs and a cat and all of them are happier with it on. Highly recommended. Much cheaper than pet specific products like adaptil and feliway and works better. Thank you to the manufacturers!
