Well, in my life (including Flicka and Pepe), I've had nineteen dogs (some were personally mine, others were "family pets"), and, of those nineteen, six were female, and thirteen were male. I currently have one of each, and I love both of them equally. My girls were a bit more aloof (with the exception of Flicka), more independant, and with a much higher drive. My males have generally been more dependant on me, more all-over-you-in-your-face affectionate, and their drives have varied...from my super high working drive Irish Setter to my extremely lazy, could-care-less beagle.
I like having a mixture of both in my house. I've found that when I have a male-female pair, they tend to bond more closely and tightly. When I've had multiple dogs of a single gender, they seem to have more of a love-hate relationship.
Now, as for cats, I currently have a female. In the past, I've ever only had males - I have found that I definately prefer the males...no offense, Lil...
