I have to agree with the other. My boys are definitely more loving. My females all vary in personality. Some are total lap dogs while others are very busy all the time running around, looking out the window, barking and getting into things. The downside to a male is that some of them have a tendency to 'mark' if they are not properly potty trained. When you have intact males around females that are in heat the males can be a real pain and they just have one thing on their mind.
They bark, whine and pace. Intact females are moody and have personality changes right before and during their heat cycle and for up to two months following.
Which ever sex you decide to choose I would ask about the personalities of the parents because I find that the pups often grow up with similar traits. Of course, if the parents have different personalities you won't know until the dog is older who he will take after. I have one female that is very active, she is 5 years old. She gets terrified of thunderstorms and her pups all seem to inherit her traits, very active and scared of thunderstorms.
Best of luck to you!
