Lupine®’s Ruby Cube is a modern, tasteful dog collar design that looks splendid on all large dogs – regardless of gender or breed. The geometric cube design is vibrant, artistic and very unique. We absolutely love it. Plus, it is finally available in Martingale style for Greyhounds and more.

What is a Martingale Style Collar?
Also called a limited-slip collar, the Martingale Style collar is very effective on dogs that back out of regular collars. Lupine’s Martingale Style collar is self adjusting so your dog cannot slip out of it. A good choice for Greyhounds and other dogs with small heads and large necks. This collar should never be left on unattended dogs.

Lupine dog collars are lightweight and durable ensuring long lasting comfort for your pup. Regular, adjustable style dog collar also available. Matching leash and dog harness also available.

Lupine® products are GUARANTEED (Even If Chewed)®. Now that’s a guarantee with teeth!

For walking and training only. This collar should not be left on an unattended or unleashed dog.
