I totally agree with everything you just said, however I do sometimes take Tango's collar off. Not often, but I do like to give her neck a bit of a break and I only ever do it at bed time and put it right back on in the morning before we leave my room. There are those times though where people who normally have their dog's collar on 24/7 take it off for whatever reason (brushing, swimming, bath, collar change, etc.) without thinking anything of it and the dog leaves unexpectedly...I do feel awful for those people because they are responsible owners who just happened to take their dog's collar off at the wrong time. I hate it when people use microchips as an exchange for collars...chips never, ever guarantee your dog is going to come home. Most people don't even know about them. Plus, a lot of times people will see a collarless dog and think it must be a stray whereas if that same dog had a collar on, they'd willingly take it home because they know it has a family out there somewhere. Then there are those who leave collars off for safety reasons (ex: multiple dog homes might have an issue with one grabbing the other's collar), I've never had a problem with that though (as pups my dogs learned that grabbing the other's collar was bad - it was something I would not tolerate). I'm not saying that Tango won't ever grab Morgan's collar but she hasn't tried grabbing any dog's collar since she was really young. All of that being said, I firmly believe that a dog should have it's collar on at all times unless you prefer to take it off at bed time when you now they have no chances of escaping. The collar thing is the one and only thing keeping me from ever having a show dog, because they apparently can't wear collars all the time since they'll develop a ring around the neck. I for one would rather have "collar fur" than have my dog not wear a collar. Safety is more important than appearance to me...and this doesn't just go for show dogs, but there are pet owners out there also who won't keep a collar on their dog because of this. This is all just my opinion of course.
