I have 2 Greyhounds and 2 Galgos. For one thing, it is a zoo around here. The Greyhounds are much more laid back than the Galgos. The Galgos want to share everything..beds, food, toys, but the Greyhounds do not at all. Galgos can play wide open for hours-Greyhounds are wide open for about 15 seconds. Galgos are always on the hunt for squirrels, rabbits, birds..Greyhounds not so much anymore. Galgos are always in a good mood-not so much for Greyhounds..I love all of them, but I have absolutely no social life as they all take up all of my time..Just saying..Old lady (70) with 4 bigs dogs is a joke!
