Pets with unexplained weight loss should always be checked out by their veterinarian. Parasites, kidney or liver disease and unfortunately, cancer are potential causes. Also try to recall if there’s anything that you can think of that may cause this such as switching the diet to a food that has lower calories, increasing the exercise or not feeding as much. If there are multiple people feeding Skye, it’s possible that someone is not feeding as much. I hope this is helpful and please feel free to post any additional questions.
