collar 5/8" or 3/4"

[Emcannon]

For a cavalier that is roughly 20lbs, would you recommend a collar that is 5/8" or 3/4"? Thanks!

5/8' is small I think for a 20 lbs dog. I prefer to walk Fletcher on a harness instead of a collar.

Thanks! I'm planning to get a harness as well-- looking at matching sets on etsy!

Brooky and Toby have both, I tend to like the thicker one though. Feels like it will stay on better and not cut into their throat.

I think Luke is wearing a 1/2" right now. It sort of gets lost in the hair. His regular one is the same size, but it's double layered, so it doesn't get so lost.
