Vegas goes naked at home, we have a fenced in yard and he is microchipped. I do have a rabies tag that I keep in my dresser. I carry a laminated card from our vet that says he has had his rabie shot if I would ever need to show it.
Thats a really good idea to have the laminated card! Brie wears her collar if we go for walks or go out in the car. We don't have her microchipped yet, but will. We have a fenced in back yard I take her out in to play (there is no where she can get out) but I really like the idea of having a card w me just in case.
