dog pregnancy

First, I am sorry for the loss of your dog Hunter.  There is no good time, but to lose a dog at less than a year old is awful.  I am wondering was this a health problem or an accident?

Second, it's pretty unlikely that 50% of the genes will result in 100% identical puppy.

Third, expect a lot of questions about why you had an intact mixed breed with regular (and frequent) access to an intact male to prevent such a breeding, unless it was intentional.  If the sire died due to a health condition, expect a LOT of questions and feedback about the choice (either deliberate or not) to breed him.

Average gestation period for dogs is around 63 days, depending on breed.  Since you have a mixed breed, you may not know for certain.  She should be checked by a vet at any event if you suspect she is pregnant to be sure you are providing proper supportive care during her pregnancy.

sorry to hear you lost your boy.  You should fill the list in on what happened to him.  

You won't be able to confirm pregnancy until about 4 weeks.  Ultrasound is the most certain method.  You may note changes in behavior or in her boobs, but those can happen in a false pregnancy too.  Your chance of getting an identical pup is 0, especially as the dam is not a purebred Lab.  If she's 4 and had her last litter 3 yrs ago, there's a fair chance of not conceiving.  Sometimes a bitch develops a thick mucous in the womb if she goes some years between litters and this leaves the fertilized eggs unable to implant. 

I second concerns about allowing a mating between an 11 mo old purebred and a mixed breed. 

Btw, one year is widely regarded as too young for the first litter. 

No it was an accident, he was a healthy and happy beautiful black lab. We did NOT intentionally breed them they were in seprate yards but he found his way in the yard. At this point I'm glad he did. our female is going to the vet next week for her regular yearly visit and can't go before then because of work. I am just hopeful that she is pregnant at this point.

I do totally agree that 11 months is too young, the accident accured while we where on a walk and she took off after a cat and ran onto the highway, he has never done that before and I certainly did not except that to happen. we all miss him everyday.

How did her first pregnancy go?  Easy delivery?  How many pups?  No genetic problems have shown up in the pups?  Are all the pups healthy?

Has the female had her hips certified?  Does she have any health issues at all?  Has she been wormed recently?

What kind of diet do you have her on?  You should probably call the vet now and ask whether the her diet is OK.  A week is a substantial portion of a canine pregnancy.

Nutrition for a pregnant bitch:  http://www.lowchensaustralia.com/breeding/nutrition.htm
"... if you are feeding a commercial dog food, this is the time to consider adding some fresh food to the diet. Good protein sources include raw meat such as hamburger, beef heart, kidney, lamb, pork and poultry. It also includes raw eggs and dairy sources such as yogurt, goat's milk and cottage cheese. These sources of food not only offer a high protein source, but also are also high in fat, iron, minerals and vitamins. Protein is essential for fetal tissue growth and the good health of the brood bitch and fat is necessary for energy."

I took Lucy to the vet today, just couldn't wait any longer. She is NOT pregnant but got a great health report. That's the most important thing.

Interesting.  How did the vet determine that she is not pregnant?  The lack of an early way to determine pregnancy in dogs has aggravated breeders for ages.  There is a blood test, but not before 3-4 weeks in and it is not super accurate.  

If your girl did indeed tie with an intact male and she was in heat, it is too soon to tell if she is pregnant.   

I really have nothing to add but wanted to say how sorry I am for your loss.  I do hope you will stick around and enjoy the Dog family here.  This is a very supportive place to be. :)
