Kizzy has never had a collar on. I've never even bought her one. she has the step in harness she wears all day most of the time and I take if off at night. when she goes out I either put a leash on her or I stay right with her till she wets or whatever. I keep her out at least 10 to 15 min. late at night I let her run out alone to tee but I always stand on the deck then call her and she comes right in the house. So I have her rabies tag and identification tag on her harness. It has two hooks that meet to hook her leash to. I have a tag on each hook. I dont have her name on her anywhere. I only let them put our last name, address phone # and the vets name and phone # so if anyone ever does take her or find her they wont know what her name is to call her by. But I was told at the start, they need a harness and not a collar.because of the trachea thing.
