Why is My Dog Losing Weight?
Sudden or unexplained weight loss should be reported to your veterinarian immediately. It can be a sign of a number of issues, some relatively easy to correct, and some quite serious. Don’t risk overlooking a potentially serious problem.
Cause of Weight Loss In very broad terms, weight loss occurs when your dog is burning more calories than he is consuming. But why this is happening can vary.
• There might be some internal problem that means your dog isn’t utilizing the calories he is eating.
• There may be an internal disorder that redirects calories from vital life functions.
• Your dog may not be eating as much, sometimes due to teeth problems that make eating painful.
• Your dog may suddenly be burning more calories. Cold weather makes a dog’s body burn calories for warmth, and dogs that are working hard use more calories too.
What to Do
Unless the cause is extremely obvious (such as you’ve started running a great deal with your dog, but haven’t been offering more food), you should consult with your veterinarian. Sudden and unexplained weight loss isn’t normal, and you should find the cause before the weight loss causes further problems for your dog.
