The C4 Dog Collar is the first customizable, antimicrobial, waterproof, no-stink / odor proof, no jingle dog collar. Our Guaranteed for Life ensures you will never need to purchase another dog collar again… unless of course you want to accessorize your furry best friend with more unique, fun and stunning designs! Your dog deserves the best, so C4 collars were designed to be super comfy and everlasting. They are soft, yet remarkably strong and durable as they are made of an advanced formulation of thermoplastic polyurethane. This is a similar material to the one used for snowmobile threads. The C4 dog collar’s round and smooth edges ensure a very comfortable fit. It will not pull on your pup’s fur and will not cause matting, and can withstand more than 300 lbs of force!! The C4 dog collar is super easy to clean. Hardened mud is easily wiped off with water. Or, throw it in the dishwasher, they are dishwasher safe! You can even get a matching belt set… but be prepared to get tons of compliments from strangers and friends alike. C4 dog collars are designed and assembled in the USA. C4 Dog Collars are ethically sourced, environmentally friendly / recyclable and 100% vegan. Every pet collar gives back – a portion of all our proceeds goes to rescue dogs in need which is a cause that is near and dear to our heart. If your dog could talk… ""I LOVE my new collar! They don't stink like my old nylon collars and I don't have to endure the endless jingle janglin' of my ID tags whenever I move! I also love being able to match my collar to my mom and dad’s belt - it's the best. Plus, with the Guaranteed for Life, I'll never have to go back to stinky, boring collars ever again. SCORE!
