Welcome.
When my Belle broke her leg, she was healed almost completely in 2 weeks and the break was invisible in 4. She was a bit younger than yours...
If the xrays are electronic (lots are now) you may be able to speak to your vet about getting a consult remotely as well. My specialist is Richard Whitelock at
Davies Veterinary Specialists, Dedicated to animal welfare, specialist veterinary referral services in the UK - they have a vet section to liaise with other vets....no idea if they work overseas!
Good luck
