Her entire left hind side is swollen. Her left leg is about 5 times normal size. No lumps.
Yes, it started last night and the swelling is worse today and the bruise has spread to about 3 times the area. The bruise is a deep dark port wine kind of looking area.
she weighs 65 pounds
she can't walk well due to the swelling, but she doesn't seem to be in any pain and she is not biting or licking herself at all
not sure if I understand the question: If I slowly and gently squeeze the swollen area, it takes a few seconds for the swelling to fill back in. Is that what you are asking? It doesn't go back to normal, it goes back to swelling.
