Spaying a pregnant dog !!

 I'm new to this website and I want to ask if it is possible to neuter a pregnant dog I can see her tummy is full but I don't want more dogs as she is an outdoor dog and I don't want the puppies to suffer 

There is risk with every surgical procedure. In the event of pregnancy, the further developed the pups, the more blood supply and maternal resources are being removed at the time of the surgery, assuming you are performing a completely ovariohysterectomy. This leads to prolonged recovery time as well. There are also risks allowing the pregnancy to continue, especially in those breeds with large heads and small hips. Each case should be treated individually with a decision best for the patient and comfortable for the owner.

2. Yes you can. There is an increased risk to the female when she is spayed during pregnancy versus when she is spayed routinely.

 Discuss the procedure with your veterinarian so that you understand what is involved and what to expect. Please consider before allowing this birth that there is an incredible pet over-population problem. 

Some of the shelters are euthanizing over 100 dogs DAILY. We need more homes and fewer animals to solve this problem. This is your opportunity to be part of the solution. If you decide to have the babies, know this will be more work than it may sound as you will be in charge of finding homes for the offspring as well as mom’s prenatal care. You will need to know what are signs of trouble during labor and how to care for your pet during pregnancy. 

3. It depends.

Do you know what’s actually risky?

A) A bitch carrying a litter while she’s still a puppy herself.

B) A bitch carrying a litter sired by a much larger male.

C) A toy breed bitch carrying a litter period.

If any of those factors apply, then spay her at once. The minimal extra risk involved with spaying during estrus or during early pregnancy is trivial compared to letting her carry that litter to term.
