Please take the time to research things a bit further before you advise others, espeicially when it has already been stated and discussed by so many in the previous posts. You never know who is going to take what you post for fact and end up suffering the consequences because of it.

All sites discussing how collars contribute to collapsing trachea.

My first little yorkie, Tashee, always wore a collar. I had no idea how bad it was to walk her while wearing it. She always pulled hard on it and sadly she passed away at the age of 10 from a collapsed trachea. I know it was caused by the collar. Now, my dogs never wear them while on a leash, only harnesses.
