I just had Sky out ... she feels very weak and she suddenly opened her mouth and mucus came out. She's struggling to breathe . She's acting almost exactly the way that Clint did before we had her put down. The only thing I can think now is that Clint was ill with something else in the first place (as opposed to the crushed ribs being the problem) and that whatever that was infected Sky and this is now the result.
I don't know what I can do now other that get up first thing and try to get a vet involved if possible.
