Latigo is more durable for a dog collar, but it can't be tooled. So, you have to think about what is more important for your product. It takes more time to properly sew around the buckles, keeps, and d-rings on the collars, so most producers will pop a few rivets on there, call it a day, and pump out more product. You also need to be aware when you sew a strap, that if you sew across the width, you are creating perforations which will weaken the strap. This is especially bad for a dog collar which is pulled. Think about what happens when you pull on a perforated page of paper vs one that isn't.
