She's much better now - she just has a big shaved patch! We were at the park, and she was off the lead, she went up to this other fluffy dog to say hi and the other dog just started attacking her. The owner of the other dog got her dog off and we left. At first we didn't notice the bite. But she soon started licking the patch and we noticed the (small) gash. After we took her to the vet and she got the cone on she was all depressed...
But luckily she is perfectly back to normal now. It was nothing really serious.
