BIG DOG CHAINS was founded in 2014 by Miguel Del Moral and Justin Low. Miguel is a respected jeweler from Montreal, Canada with over 20 years experience. Justin has worked with luxury jewelry brands for over 10 years in over 40 countries around the world. The Big Dog Chains concept was developed to satisfy the need for large dog collars in the pet jewelry industry. We found that there was a lack of fashionable and great looking collars for owners with larger dogs.
