our dogs have tags they we just dont renew them, no one would know any different our citys new tags are designed to last the liftime, you just gotta pay a whole pile of money every year here it costs around $30 to renew the licence on an intact dog, and the spay nueter discount reduces it to $15. all my dogs have ID tags and ear tatoos. however we dont have much of a problem as Ripley is the only one that goes anywhere, when the others get out of the yard its by accedent and they go nuts trying to get back in perky site at the gate in the driveway, shadow just goes to the naighbores house(they have no fence) and they let her back into our yard lol happy does not get out in the first place, you have to coax her out of the yard, misty acts like she will fly out the gate but when you open it just just jumps around inside and you gotta drag her out! lol Ripley goes visiting people and his tatoo gets him back here before we know he's gone, plus everyone knows he he belongs to by now lol
