I have to think that with all the bloodwork and other procedures we all end up having to have done on these dogs at some point, that you could use either blood-typing or DNA to reclaim a dog if a dispute erupted. All that info is on file with your local vet.
Seems a lot safer than the microchip, though in a general way I think they are good. Ideally, they will come up with something similar with less of a carcinogenic factor.
At home though we always say that if they ever took Ozzie
, they would bring him back!
