Planet Dog Brand Hemp Collar Made in USA

Thank you menusux and kb, I truly appreciate the information. 

Found a leather collar for my girl at Menards and cost was reasonable at $5.92. Also made in america and did not stink of chemicals.

My farm & feed store said that customers are asking for US-made leather collars & leashes for their pets, so they found a company that uses US-raised steers for its products.

Weaver Leather - based in the US and uses US steers for the leather and, I thought, solid brass findings on some of the products.  I do not know about the dyes. 

I'll let my babes grow a bit more and fill out, and then decide.  My male looks great in cranberry, and my female tends to look sharp in a bright forest green or rust.  Decisions... decisions.  HTH someone.

There's also Bebop USA, all products are made in Gresham, Oregon, and some of the profits benefit

We have a few from this place, really strong collars

They are adjustable choke collars that don't strangle the dog if they get caught, and they can hold a 130# crazed dog trying to eat the meter reader.
