All 3 dogs have tattos, Smudge and Winter in their ears, Tama on his stomach by his leg. They all also have id tags with my phone number and address on their collars with their city license (except for Tama who at the moment doesn't have one soon, I just have to see if I get to keep him) plus all three dogs will be getting chipped in the near future...well two for certain three if everything works out with Tama.
