I was having trouble with Bennett barking at night and waking the neighbors, I tried the ultrasonic one also and it did nothing, i bought a muzzle to try also. Bennett doesnt mind it, it allows him to eat drink and even chew a bone (not sure how he does it but he does...) i know it sounds a little mean but he acts completely different, he doesnt bark, even when it is off he barks less. I would try that every dog is different but its worth a try. Good Luck |
