I'm not altogether sure I agree there, MM. I've been a lifelong dog owner (until the last three years)
Our beloved old Paddy was once chased by a dog which wouldve killed him if it had caught him, but he had the good sense to head fr a tight space the dog couldnt follow. The dog, in it's rage, went to bite me as I tried to restrain it. Luckily, he didnt do much damage, but it couldve been a whole lot worse.
The dog was visiting our neighbour, and the woman who owned it knew full well it hated cats, but she persisted in letting it off it's lead even though she knew the cul de sac had no fewer than 5 cats living there at the time. I love dogs almost as much as I love cats, but a responsible dog owner should know what their dog's reaction is to stimulus and should take steps to make sure it remains under control.
I wonder if she'd be quite so concerned if you sent her the vet's bill for Martha's treatment. Just saying.....
Anyway, getting worked up about it wont change anything at this stage, but it sounds like it's just as well you're moving soon.
You may find when Martha comes home her confidence will have taken a bit of a knock, and you may have to work with her in that respect, especially with the move pending. She may well be her old rumbunctuous self of course, but worth bearing in mind she might not.
A change of environment on top of this could make her a bit wary. Lots of Martha's Mummy cuddles are in order I think when you get your little girl back home.
