We often go for buckle collars but know that our dog walks best with a martingale. The reason we use buckles is because our pup has an odd shaped head and we take his collar on and off for walks so it doesn't get caught on anything. I love being able to buckle on his collar while having a martingale!!
We got our first collar from twelve paws and I am thrilled! The quality is amazing. Fabric is beautiful, soft and flexible. The chain is good quality. The buckle looks like a simple black buckle, but it is so easy to clasp shut and to open. It is a thin profile and nice and light without compromising durability. Would buy another collar for sure!
