The normal gestation length for a dog is about 63 days so I would expect her to have puppies by now if she were pregnant. I think you can safely breed her at her next heat cycle which will probably occur in the next two months. If she had a litter of pups a couple months ago I would recommend skipping one heat cycle before breeding again so the bitch can fully recover. Be sure to have her examined by a veterinarian before breeding to make sure she is in good health.
