Any where from 18 months.
However old it is when it gets pregnant.
Yes. A woman can become pregnant after her first time. It is an old myth that a woman can not become pregnant after the first time. Unless birth control was used properly, there is always a chance that she is pregnant.
10 years old We had a collie bitch who had a litter of 3 puppies when she was 18 years old, so don't become complacent!!
you shouldn't get a very old dog pregnant it is unhealthy for them
At least 3 years old
Yes. You can get pregnant no matter how old either one is.
Yes, a six year old dog is capable of getting pregnant.
A.S.A.P!! your breeder should have done it when the dog was pregnant and first couple of weeks old.
No, they are too old. If they do, you will be risking their life.
If the 6 month one dog has tedticles and is sexually mature and neither if them are neutered, yes.
It's ok for any breed of dog to be pregnant at 1 year old but most breeders let go of the first heat.
