She's a five-year-old (turning six next month) Australian Shepherd/Chow Chow mix. I'm not sure how much she weighs right now, but I think it's between 60 and 70 pounds. She has no chronic health problems and is slightly aggressive towards other dogs, so should not be held in the waiting room while other dogs are present.

Thank you so much! I hope everything goes well (well, as well as it can) with your family situation.
