I've never collared my dogs. This is mainly because Lou has a needle dobie head and slips any collar off and loses it. I gave up after several lost collars. I also find them to get in the way of the high leash when walking.Gator used to act weird when you took his collar off too and wanted you to put it back on. He wasn’t really anxious and didn’t really care but he loved to sniff it and check it out and acted like he wanted you to put his “bling” back on
