There must be some sort of protection for the dogs here, are you sure your vet has not said that they have suffered mental and emotional distress from this incident and the fear of being attacked in their own home?
Not a sarcastic comment.

I’m sure no harm done whatsoever!
Roo (my girl) is the feisty one and undoubtedly the one who would have seen off any perceived threat.
Marley on the other hand is huge, taller than me when he jumps up, yet literally scared of his own shadow! A big baby!
Neither is aggressive nor prone to biting etc, but, Roo most certainly likes to guard her pack (us) I’m quite sure she carried out this aspect of her personality perfectly today.
I’ll wait and see if there’s any come back but, I’m doubtful to say the least.
Still can’t quite believe said shyster was stupid enough to put his hand through, then again, the criminal element is rarely endowed with intelligence....
I’m hopeful nothing else will come if it and if it was to do so, I think I and my dogs position is justified, let’s hope eh?
The culprits.....
Roo in the foreground.
