At least 3 years old
However old it is when it gets pregnant.
you shouldn't get a very old dog pregnant it is unhealthy for them
Yes. You can get pregnant no matter how old either one is.
No, a dog must be in heat to mate successfully. Otherwise she will not get pregnant.
Yes, a six year old dog is capable of getting pregnant.
Once the ovaries and uterus have been removed from a female dog, it is impossible for her to get pregnant. If a bitch 'believed' to have been spayed does get pregnant, it must then become obvious that the dog was never spayed.
If the 6 month one dog has tedticles and is sexually mature and neither if them are neutered, yes.
The male should be a few months old before mating and his testicles should have dropped
can a 15 year old male dog make puppies with my 2 year old dog
Any where from 18 months.
about 10 weeks old
well it depends if your dog was having her period and they did it right there should be a chance that the dog is pregnant if she did not have her period she will not get pregnant but if she is having her period she will not have puppies if she does not have her period and has sex she is doing it for fun but do not force it on your dog
