Yes, mine wear bells and believe it or not I know each dog by the sound of the bells!!! lol! They all sound slightly different...it's wierd and unplanned but true!!
Mine are very good about "getting out of the way...but when they were puppies we had to be careful. Ava won't even go through a door if someone is touching it...she waits until the coast is clear or you have to carry her through! She has never been stepped on which I bet most people cannot claim for their 5 lb and up yorkies.
