Geez Cleo, I could almost wear your collar as a belt!

Rupert's neck is about 14". He has two 1" flat collars (one blaze orange with a reflective stripe, one rubber - Dublin Dog) and one fancy 2" flat Collar Mania collar.

This thread might come in handy for the next Secret Santa or happy mail. 

Willow's is 18 in., rolled leather. 

Talus' regular collars are 28" ...his leather collar is 30" (it's studded)...

He only wears his collar on walks and in the car...

Bella wears an adjustable size 8"- 12" plastic snap buckle collar. Its adjusted to around 9 inches or so. 

I actually measured my dogs last night.  I measured based on collar (so there's probably an extra inch or two since my dogs are double coated, the collar is not tight against the skin). 

Kenya 17"

Nikon 20"

Coke 19"

 Charly has in german size 0.

Keira - 15". Width wise, she has a 3/4" nylon collar and a 1" leather collar with the buckle area tapered to 3/4". Her martingales are 1".

Dance - 14.5" and a 3/4" wide inch collar.

Spring - 14.5", and a 1" wide collar.

Ripley - 12" at the moment, 3/4" wide.

Dahlia wears a size L (17-28 inches), 1 inch collar.  This one, for anyone interested in what it looks like.  Alas, it's usually buried in her fur and not that noticeable.  If she didn't have tags on it, it would often look like she's not wearing any collar.
