Bests & Worsts Reviews from Amazon

After less than 48 hours, we had to return these. We put them on at 5pm on 5/16 and took them off on 5/18 at 1pm. Our dogs both developed severe redness, irritation, and their normal activities changed. We started noticing the very next morning that our youngest started having mood changes. He went from a very happy active 2 year old to sleeping all day, with rapid jerky movements. He acted like he was on drugs or had severe mental disorders. He would be sleeping, then run around in circles a few times and dash off to hide. He stopped eating and was generally not as vocal. We decided to give it a few more days, but when our other dog who is smaller, got the same issues, we decided that these must be defective or something.
