This was it yesterday evening:
It's a little dark but nothing too bad, about an inch in length and width.
Here it is this evening
sorry for the crappy picture, but the purple from her neck to the top of her chest is purple, and the knot has traveled down. It is now about 4 inches long and 2 inches wide.
Has this ever happened to anyone else?? I'm defintely either calling or running her to the vet first thing in the morning. They said the reason it formed is because the only place they can get a good amount of blood is by taking it from the jugular and it's just like a human that bruises after blood is taken. But should it be THAT big??
