the male has a penis and the female does not
From looking at the dotted of them
ummm..............
A boy has a penis and the female doesn't.
They have no gender. They are "its"
To be able to tell the difference between a girl or boy puppy look at the genitals. A male dog will have a penis and a female dog will have a vagina.
When they are born
The same way you tell if it's a boy or girl dog or human.
The male has a penis and the female doesn't.
the girls have nothing on their stomach but boy dogs have something hanging there, i know its gross, but that's how you tell
Because a girl dog has a female part and the boy dog has a male part that's how you can tell from the female dog and the male dog the way you can tell you watch the way they pee. boys stick their leg up and girl don't.
You can see the penis on a male just like on a dog
Lookk for OBVIOUS signs to distinguishh if the dog's a girrl or boy, && if it's yourr dog, even after surgery you shud still know what it is....
Does your dog have a penis? If yes, then he's a male. If there's no penis, it's broken. Return it for a new dog.
