How Long Does A Chinchilla Stay Pregnant?
Duration of full term pregnancy in dogs can be of 59-68 days with an average of 63 days or 9 weeks. Vets recommend not to breed your dog until the age of 2 years. It is necessary to get ultrasound after 50 days of canine pregnancy to know abnormalities in puppies and size of litter. If dogs don't deliver around 70 days of pregnancy then it is time for vet visit.
