What a shock for you, sending lots of these

to start with.
With the results of the X-rays I'm sure you vet will be able to give you a much clearer picture, which will help you I'm sure. When we only know half the facts our minds naturally go into overdrive, which isn't good but can't be helped.
There was a thread a while back about a cocker who had a leg amputated, sorry cant remember how long ago it was but I do know the dog was just fine and adapted really well.
My sister had a rescue dog who'd had a leg off due to an accident/cruelty and she was like a little rocket, it didn't slow her down!!
I hope they get back to you soon, keep busy xx
