Hi - I adopted Mindy from the Humane Society - a Greyhound mix. 50 lbs, 1 y.o. I'm thinking the "mix" is Terrier because her prey drive is fierce and she's always digging and trying to flush out lizards and toads; she has accepted that I won't let her chase down ducks or neighbors' cats - or our Chihuahua who's meek. Very determined, independent, strong ... and loving. Does Terrier make sense? Thank you...
