The new dog will wear one the majority of the time until he has a recall , once we are at my apartment he doesnt though. He would have to make it through two doors to get outside.

All dogs collars have rabies , license , microchip tag , and in Caesars case another form of ID tag that has a pin number that can be put online and will bring up his profile with my number and address etc...
