Review on MIYOU YOUMI Ultrasonic Dog Bark Device - Advanced Anti Bark Deterrent with 3 Adjustable Levels - Stop Dog Barking Up to 33 Ft - Indoor and Outdoor Use by Melissa Cunningham

My sweet 13 year old savior has been attached to me since day one. I stayed with him for the first week and then went on short trips, to the mailbox etc. I ended up leaving him for a 1 hour yoga class and he barked the whole time according to my frustrated neighbor. I ordered this bark remedy after reading and reviewing them all and googling these types of devices. Works great, doesn't bark when I'm gone for average hourly splits. But I feel like I'm punishing him and he's stressed when I come home. I would like to know what others think. I've been using it for a few months now and it's still working on the initial charge. It's amazing and I found that even if I don't use it he will be stressed. But at least my neighbors don't complain anymore.
