Why do my male dogs offer me their belly to rub, but not my female?
 

Just curious. Is this a male only thing? I just find it weird that my female does not do this. My males love their chest and belly rubbed, and roll on their back for me to love away. I don't think my female has ever offered me her belly to rub. I never made this connection of the genders until today, and I've had these guys for 5 years. Weird, so I thought I'd ask.

Many of my female dogs offer up their stomach, it's not m vs. f, but individual dogs/traits.
Some dogs are just less...affectionate isn't quite the word I'm searching for, but basically some are a little less...demonstrative, yeah. And females tend to be on the less demonstrative end of the spectrum.

Guess it just depends on the female, I have a female and every time I finish brushing her she wants a nice belly rub. I can say however when I'm not grooming her she rarely wants a belly rub maybe every once in a blue moon.

Yeah, my boys will constantly flop down and roll over when I approach, showing me their bellies and begging to get rubbed. Nara will only let me rub her belly if she's already on her back, like while she's sleeping if she wakes up. She'd rather sit in front of me and have me rub her neck and upper chest while sitting.

Had plenty of females offer up their tummies for a good scratch. All of my girls love belly rubs. It is the dog - not the gender imo.

Lisl loves it. I'll be petting or playing tug with her and she'll roll over for a scratch or a rub or a little pat on her belly.

all my dogs male and female love the belly rub. not m vs f, but maybe a dominant/ submissive thing.

Keefer is the most affectionate dog we've ever had, but he never rolls over on his back. Halo (female) loves to roll around on her back, and will lay there while you rub her tummy.

Depends on their social status. Higher ranked dogs will not roll on their backs as easily as the more laid back ones.

That would be the opposite in my house. ;) Flexibility may have something to do with it too, Keefer was never a back roller, even as a puppy.
