I’ve had this for 4 days now plugged in and so far it’s amazing. My dog is 9 years old and suffers terrible with separation anxiety. When ever we go to bed or go to work she would shake before we leave and we would always come back or come down to pee all in the kitchen. Since I have had this plugged in not a single day have we come down to pee in the kitchen. So for so Good! She’s like a new dog!
