Well, I have both. 4 girls and a boy.
I used to be ALL about girls...and yes they
are fun to dress up and spoil...
And honestly, my girls are, for the most part, just as affectionate as a boy. Now, Sophie and Brooklyn have that streak of female personality, where they want to be off by themselves and don't like a lot of cuddling...BUT that's usually only if they're mad at me...lol. Maddie and Mikayla, however, are both very loving and follow me everywhere. I love my little girls to death.
But, there's something about having a little boy too...my tiny guy...
He's just SOOO loving...always wants to give kisses...and loves everybody. Now, I have to say, my girls DO bark at everyone else and are VERY protective of me...which I sort of like...but boys aren't usually that way...
Anyways...it's a tough decision. Do you tend to like the more independent and protective nature, or the loving and friendly nature? Although...you could get an independent boy and a friendly girl...lol.
I think someone else mentioned that it really depends on the individual dog...so when you find a reputable breeder, spend some time with both...and see who suits your personality better. OR you could get one of each!!!
