So my dog Foxy is a Husky / German Shepherd mix and she is 5 years old. She has always been around 70lbs, but in the past 2-3 months she has dropped to 48lbs. She was tested and scanned for all types of Cancer, liver disease, Kidney disease, infections, etc. She has had urine and stool tested a number of times with no issues, no worms, very mild UTI which has been an issue forever because she was spayed too young but it is under control now after surgery about a year ago. She has had 3 separate blood tests for everything under the sun and they're all coming back normal. No thyroid issues, no pancreas issues. I thought for sure it was EPI because she lost weight and she's eating like crazy, including eating poop sometimes, and those are signs of EPI. That came back fine though from Texas A&M where my vet sends those blood tests. They are running out of ideas at my vet and I hate to watch her waste away. She still has a ton of energy and acts normal but you can see her ribs and hip bones through her relatively thick coat and I can't stand it. Normal weight for her is around 65lbs, since when she was 70 the vet said she could afford to lose a few lbs. She has been around 48-50lbs for the past month, so I'm not sure if she's getting any smaller, but I worry that she isn't absorbing nutrients from her food. Any help or info would be greatly appreciated. Thank you!
