I ordered Sadie & Max new collars with their name and our phone number embroidered on them. I am always worried about the dog tags getting caught in the spaces of the kennel so we take the collars off each time we put them in. Now with their names & our phone number embroidered on the collars there really is no need to wear the dog tags. Without the dog tags we should be able to keep the collars on when they’re in the kennel without worry and they still have our contact information on them incase they would ever escape the backyard. We have a fenced in yard and are real careful when we let them out, if were not right out there we check on them often but you never know what can happen.
