My dogs are all currently wearing rolled leather collars with Boomerang collar tags (the slide on non-dangly kind). I do NAME, CELL, EMAIL, MICROCHIP#, MICROCHIP PHONE.
In the summer, they all wear biothane collars from GDS and the plates on those say their name, my cell, MICROCHIPPED.
When I have some money, Limit is getting this collar (he's the only one that has a short enough coat to see pretty collars), and I'll get a dangly Boomerang tag that says all the info except his name (which will be on the collar).
Mine do not wear any rabies' tags (although they are utd) and I don't license mine either.
