What Weight/Ounce for dog collars?

[apeek]

How is everybody doing?!

Newbie here looking to make some dog collars for friends and my pup!

I am not sure what weight to purchase.

It seems 8/9oz is what most people use but is this flexible or would it be stiff?

Or would 7/8oz be better suited?

Thanks!

Well........THE BIGGER THE DOG THE THICKER THE LEATHER..

if you have a sewing machine you can sew two pcs together.

I have German Shepherds and I use 6/7 & 7/8 doubled. I do work my dogs in protection and tracking, so it might be a bit of overkill for a well-mannered dog of that size. I don't have the luxury of a sewing machine, so it's all hand-stitching for me. I'd only hurt myself with a machine. As long as there's football, I'm good for hand-stitching. lol
