Bests & Worsts Reviews from Amazon

The good news was that my dog had no fleas. The bad part...my dog started experiencing very severe neurological symptoms about 8 weeks into use of the collar. We initially did not think it was the collar. The started knuckling a lot while she was playing and would lose her footing easily while running. This was very out of the norm for her. Then she would be walking and her two back legs would just go out and she could not get up. She was unable to jump on the bed or the couch and had to be picked up. She would have random severe muscle spasms while laying down. We took the collar off and went to the vet, who was very concerned. Thank goodness all of her blood work was good and there was no kidney or liver issues or detected cancer. It took about 5 months before she was back to more normal. Her one back leg still doesn't seem to be the same, but she is alive. If your dog starts experiencing any of the above mentioned symptoms, take off the collar immediately. I wish I had never bought this. I believe it almost killed my dog.
