We have a pregnant springer spaniel, today makes day 59. The dad is a cocker spaniel. How much larger can a puppy grow the last week of gestation? Is it a significant size increase the last week of gestation for a dog?

Puppies definitely continue to grow the last week of gestation and there are important developments that continue to occur, particularly with the lungs. It's difficult to say exactly how much - we don't have a good way to estimate a puppy's actual weight or size with ultrasound or x-rays like in people.
