I have a breed that seems particularly susceptible to broken legs, the Italian Greyhound. It is what happens when kamakaze puppies have pencils for legs. There is one thing that concerns me about this story. Splints are not "inserted" into a dog's leg. Pins and plates, but not splints. Splints are rigid supports that go on the outside of the leg and get wrapped up. They get changed. It is advisable to xray the leg as it heals to make sure there are no complications and that it is healing and healing properly. I personally am not comfortable with splints, unless the fracture is a hairline fracture, but it is the cheapest way to have the leg fixed, requiring no surgery. It can also cause complications later in life, but I've had a dog whose legged was pinned and it healed crookedly. As for my dogs, I would only have an orthopedic surgeon handle the repair.
I hope you had the owners sign a spay/neuter contract before you sold the puppies.
