I like to keep a collar on Ginger (when she's not crated). I NEVER use it to walk her, but each of her collars has an i.d. tag attached. Hopefully, if she ever got out, she'd be wearing a collar.
I never leave her harness on after her walk because it tangles her hair. Therefore, putting the tags on the harness would be worthless.
As far as size goes, they're all so different. But if your's will be a pup at first, I'd say you'd be safe with the smallest one for now.
When do you get your little furball? |
