Zoe's other half

when we bought Zoe, they told us at the shelter that he was half chiwawa and half something else, they didnt know... after having him for a couple of months , and still eating whatever he might find from the underwear (he really ate almost all ) and opening doors that we close, moving chairs and climbing to get what he wants , sniffing after garbage despite he food we serve him ..totally annoying ,disobedient and really faceless... i admit he is smarter far beyond my expectations ... i kind of sure that his other half is MAN ...
