Is my 7-year-old pregnant dog too old to safely have puppies?

In the pet's information, you have it listed that Cookie is spayed. If Cookie is spayed, she is unable to become pregnant. However, if that is incorrect, I am not sure if Cookie has had a litter of puppies before. A dog that has never been bred before who is an older dog such as yours might have problems whelping due to the pelvic bones losing their elasticity making for a very hard labor. Your dog may need a c-section to deliver. I would be prepared for this in advance. In addition, I would consider having her spayed at the time of c section (if she has a c section) because pregnancy is hard on older dogs, and I would not recommend her having another litter after this one. There is a higher chance than normal for a difficult delivery due to her age, and there some signs to look out for, such as a foul smelling discharge during labor, strong steady contractions for over an hour without any puppies being produced, the mother is very tired and/or vomiting during labor. I would suggest speaking to your vet about additional signs to look out for labor, and having your vet examine Cookie to make sure she is healthy during this pregnancy.
