Near miss.... (hopefully!)

He's full of mischief and runs about daft like any pup... But this evening, whilst having fun with Flynn (who plays very gently with him) he landed badly rolling over with Flynn whilst having a tug of war with a stuffed rabbit. He gave out an almighty yelp, and my heart in my mouth I went to pick him up, his leg was limp and I feared the worst.
When I put I'm down he slowly started to put weight on it.... He then went for a sleep and I've just had him out and he had a little limp, but definitely putting weight on it and I'm going to assess it again in the morning after he's rested it properly.
Fingers crossed it's just been jarred and all will be fine.
Think Flynn feels bad.... :-(
But ie told him it's not his fault.
I actually have it on video and Flynn is definitely being gentle.
Sure all will be fine... But paws crossed for the wee mongral! :-\
