Don't judge me by looks!

my name is Ruthie. I am a very lovable pitbull mix? i love everyone and especially little kids that are more my size! and eye level. I will only lick them to death at worst! but i hear their humans tell the little ones sometimes to "not pet that one, he's mean!".....for one, I'm a SHE and for two, what does "mean" mean??? I miss out on lots of pets and hugs sometimes and that's not fair!!!!! i'm glad my mom and dad sure love me no matter what "breed" i look like!!! I'm just ME, Ruthie!
