I have one of each and they are as different as night & day! Both are Loyal and clingy in their own way......Artie is very mellow, sweet, affectionate & loving. Abigail is a Terrier, always hunting, chasing, digging and getting into troulble, stubborn. If she kisses you she acts like she's doing you a favor.
Artie learns much faster and I never have to reprimand or correct him after I've done once. Abigail on the other hand you have to do it over and over, once she gets past her attitude. She still sleeps in the Bed with us and niether one of them leaves my side, even when I'm on YT. One is on the Desk and the other is sleeping in my lap. I do prefer the males simply b/c they only want to make you Happy and are more eager to please! I still dress him and have a topnot in his hair everyday as well as Abigail, I just make sure he wears gender correct styles & colors......sorry No Pastels fo him. They compliment each other, what one is lacking the other has. So it balances out?
From what I have seen males love woman and the females love men, I can tell by the way my 2 interact w/me and my BF. that, that is true in my case.
But to begin with I chose both for their Personality and how they interacted with one another, I actually let them choose each other when I went to pick her out @ her Breeder's House! Good Luck deciding......they usually choose you anyway, even though you think you are choosing them
