Review on 🐶 zhyUS Waterproof Dog Training Collar - Beep, Vibration, and Shock Modes, Remote Control with 1000ft Range - Ideal for Small, Medium, or Large Dogs by Teresa Thomas

Bought 2 pink for a girl and blue for a fur baby boy. Easy to assemble. I don't use percussion, just vibration. I've only used it a few times for excessive barking and they seem to have figured out that barking 1 1/2 squirrels in a row is not okay. Update: I use them as a study guide every day. I don't need them after vibration #3. My two puppies don't mind wearing them at all. I bought them in December 2019. Having 2 dogs that have the ability to tune into different channels has been great. The only negative I can think of is that I wish they had a lock button or an on/off switch, several times my grandson would reach for it and start pressing the button, my poor dog would get sleep fixes!
