I've had many dogs as well. I have generally preferred to have girls bc of the leg lifting/ marking behavior with males. BUT, that being said, my Brooklyn- yorkie female- is fiercely independent, extra playful and not a cuddler at all. My dearly departed Spike- a pomeranian chihuahua male- only lifted his leg outside and was a snuggle bug. So yeah, it's definitely the individual personality of each dog that matters most. All my pets have been wonderful to me.
