Aww, poor baby! I do know from personal experience when my old dog Kacey broke her leg when she was about 14 or 15 weeks old that she was able to fully recover from her injury, so I have faith that your little one will be able to do the same. The only thing that did end up happening was when Kacey got older she did develop arthritis in that same hind leg of hers that she broke when she was a puppy. Hope that helps.
