Thank you both for your replies, very much appreciated.
I will get her to a vet asap.
I can't actually see her tail bobbing at all really and as for a swelling, she moves every time I get near her. She actually seems fine tonight.
I think I'm going to have to put some thick gloves on and try to wash her myself.
I've just managed to track down her breeder and we've had a chat. He's suggested I massage oil into her. The things you do for love, I could lose a limb here!!
Thank you again
