Review on MODUS Ultrasonic Dog Training and Barking Control Device with 3 Modes - Rechargeable Deterrent for 🐶 Dogs - LED Indicator - 16.4 ft Range - Portable and Safe for Indoor and Outdoor Use by Eric Hall

I bought this for my Rat Terrier. In a nutshell. As soon as it was delivered, the dog started behaving differently. I didn't think anything of it. An hour later I opened it. My dog started shaking, convulsing and gagging non-stop. That went on for over an hour. THE DEVICE WAS FULLY CHARGED. IT WAS AT THE HIGHEST LEVEL. THE POWER BUTTON WAS PRESSED. Who knows how long my dog has suffered? All I know is that my dog isn't normal anymore. He no longer knows how to do elementary things. Last night I had to feed him his favorite peanut butter ice cream. He's been to the vet multiple times. They don't know if we're getting out of there. MY SMALL DOG IS NOW ON A HIGH DOSAGE OF TRAZADONE. The picture above shows that my dog now does this 90% of the time.
