I don't think it can get pregnent.
Um...I think the female dog can get pregenant at like, less than 6 months old. My friends dog did. I'm not sure when a male dog can make a female pregenant though...
Yes it is very possible.
Well, a female dog can get pregnant as early as 6 months...but it's not recommended to let a dog that young get pregnant, it's like letting a 10-12 year old human get pregnant...it's possible biologically but not good.
Nothing will happen. She won't get pregnant, since he lacks the tools to impregnate her.
Every kind of dog (female) gets into heat from 6 months of age and then every 6 months. (only if not spayed)
It's either that or an illness. Call your vet.
NO
However old it is when it gets pregnant.
If the female is trying to get pregnant with a male dog then it will go on the males back but if the female dog is going on the males back while pregnant then it may means that they wanted to have another baby.
By mating with a male dog.
Yes. A male dog becomes sexually mature at his 9 months of age, and a female at her 1 year and 2 months. So, she might be pregnant.
No
