What makes you suspect she might be pregnant? Was she around an unaltered male while she was in heat? Was she left outdoors unsupervised during this time?
If there was the possibility of her coming into contact with an unaltered male during her "heat" cycle, yes, there might possibly be a pregnancy. A trip to the vet will provide the answer, one way or the other.
First of all why do you suspect she might be pregnant.
Take her to the vet and have the pregnancy stopped. I am not going to lecture you on spaying or how could you or any of the other comments I have read above. I don't know your situation. If you have an intact female and she goes into heat you must keep her under constant supervision and avoid letting her near any intact male, or any other dog since you might not know if it is an intact male or not.
My 2 year old female is currently in standing heat and my 3 year old male is going crazy, he can't help it. The good lord gave two instincts to all animals that over ride all other instincts...... The instinct of survival and the instinct to breed, which initself is survival of the species.
The creator gave her the ability to get pregnant at this age so I am not so sure how dangerous it is, but, I believe she is not ready physically or mentally for babies at her age, go and have it taken care of.
Take the dog to the vet to get her castrated right away. A dog shouldn't be having puppies until two or three years old, not nine months!! If she does end up being pregnant and having puppies, she will most likely die, which would mean her puppies will die.
A dog's gestation period is 63 days. But what makes you think she is pregnant? Was there a unneutered male around?
the first thing I want to say is how dare the people critisize you. There are many signs of a female in heat. THE FIRST is the constant cleaning o her privates and TWO you will notice swelling around the vagina. You may also see spotting where she sits. On the othrhand some females clean themslves so well that you will never see spotting. I would suggest taking your dog to a vet. This is one of the things you need to watch out for if you do not have her spayed. They also sell Cloth diapers for females or wrap for males if you are not having either fixed. I have learned little traits over the five years of breeding that I have been doing. I hope this helps...
If you had planned on getting her spayed eventually anyways, then please go ahead and have it done NOW. Some vets still use the mis-mate shot (mine does not) but I do not recommend it. Comes with it's own additional problems. I assure you she will be a lousy mother. And it will not even be her fault.She probably won't keep them clean, may not lay still to nurse, and she may lay on them. She may not even want to stay with them for long.She is a puppy. This is terrible. A puppy should not be having puppies herself. If you decide to let her have them, please be sure to be present when they are born and please start reading up on everything to expect and on what to look for as a sign of trouble. This is not good for her health. At her age she still needs all her nutritional intake for her own body to continue maturing on the inside. A 9 month old cannot spare what it takes to grow and nurse puppies. My doxies do not have their first litter until they are 2 years old.
I am not bashing you for this happening (as long as it's not a pattern) , accidents do happen. But you can do something about it to rectify the situation. But if you do nothing you deserve to be bashed then. Please spay her now.
