I have a 17 year old female dog and she has started losing weight rapidly. She also is having trouble moving. She eats and drinks as usual. I'm very worried.

I would be worried about Kane as well. In a senior dog, this rapid weight loss could be due to liver disease, kidney disease, heart disease, diabetes, or cancer to name some causes. If she is having trouble moving, that suggests she is in pain. I'd take her into a vet right away to get checked out. Best of luck.
