The city of Montreal and many other cities and provinces require your dog to have a harness or collar. Angels believe keeping a collar on your dog not only helps restrain your pup faster to prevent him from getting into something dangerous. A collar or harness with tags on them helps your dog get found much faster should he ever get lost. The Angels require all our daycare, dog walks and hotel guests to wear a collar and an ID tag for security purposes. Keep your collar in good condition to avoid the collar from breaking while your walking your dog. Take a look at our products we have ones that lare durable and others to look fabulous. Enjoy shopping for your pets!
