Indy and Ava only wear their collars when they are going to be outside of the closed areas, in the house or the locked, fenced yard.
When they go for rides or walks, they always wear their collars.
All our prior dogs wore their collars at all times, but since fencing an area for Indy, the collar(s) are normally off.
There are arguments for both sides. Dogs have strangled when their collar, or the tags got snagged in a crate. Dogs have strangled, or nearly strangled when a leg of one dog has gone through the collar of another during play.
I was only made aware of this in the past couple of years, and arguments can be made about dogs that manage to escape without a collar and don't get returned.
It's a choice we each have to make.
It is nicer to be able to run your hand over them without the interference of a collar.
I would liken it to making love with your clothes on.
Sorry about the exaggeration. No, I'm not either.
