The pet safe lite collar is the best decision we’ve made for our moodle Teddy!! I’ve tried everything to help him with his severe separation anxiety. The Dog Trainer said it was the worst she had ever seen. We tried the citronella collar, but I actually had to come home half way through the day to add extra citronella because he just kept barking. He would foam at the mouth when we left home because he was so stressed about not being around us. After two days of using the pet safe light collar he barks once or twice now and then goes to his bed and he’s quite happy to stay home alone for an hour or more. The best investment! I would highly highly recommend it for any oodle or any dog with separation anxiety Thanks petsafe Cindy
