My two never have collars on unless outside the house. Right now I don't have a yard but a tie out for potty time, so they get a leash on, then put on the tie out. If and when I get a yard, they will get collars put on before they go outside, but taken off when they come in. It messes up the fur on their necks and Doc is a conformation dog, so I cant have that happening. Delta doesn't because she started to loose hair on her neck from the rubbing. Plus the jingles is just annoying. I have lots of collars, martis, buckles, quick release, they would never wear a marti in the house for fear it would catch on something. I did have them wear their new martis for a weekend to break them in. (Custom made and 2 inchers, so they were a little stiff. Lol) But that's about it.
