I’ve had a mild concussion, didn’t lose consciousness, didn’t need any actual treatment.
It was the weirdest week of my life! I was clumsier even than normal, really confused - like couldn’t make decisions, even dead straightforward ones, couldn’t remember words for stuff and had mad mood swings where I’d suddenly be crying... over nothing.
I went to the GP because I was a bit freaked out by it, going, I hit my head quite hard yesterday and now I don’t feel right, he’s there going, yeah, concussion and I was arguing with him, because I was for some reason sure concussion would be more dramatic, lol... anyway, turns out they’re all concussion symptoms.
I just had to go away and rest till it got better.
So the point of that was, she may well act weird for the next wee while and it doesn’t mean anything sinister is happening. Obviously go back to your vet if you’re worried, but also expect her to be a bit off.
