Dog suddenly thin but eating everything in sight except her own food never gotten into the garbage before now if we confine a daily occurrence She is 13-year-old GR?

I understand you're concerned about your 13-year-old German Shepherd's sudden weight loss and change in eating habits. It's important to take this seriously and seek professional help.

Here's what I recommend:

1. Vet visit: This is the most crucial step. Your vet can perform a physical exam, run blood tests, and possibly other tests to determine the underlying cause.

2. Describe the symptoms: Provide your vet with detailed information about your dog's weight loss, appetite changes, and any other unusual symptoms. Mention the specific garbage-eating behavior, as it could be a clue to a nutritional deficiency.

3. Consider potential causes: Some possible causes of sudden weight loss in senior dogs include:

* Dental problems: Painful teeth can make eating difficult.

* Parasites: Internal parasites can cause malabsorption of nutrients.

* Cancer: This is a possibility, but hopefully not the case.

* Kidney or liver disease: These conditions can affect appetite and metabolism.

* Diabetes: Less likely, but possible.

* Thyroid problems: A hormonal imbalance can lead to weight loss.

4. Be honest about feeding practices: Share your dog's feeding routine and the types of food you give her. This will help your vet assess her dietary needs.

5. Follow your vet's instructions: Your vet may recommend dietary changes, medications, or further tests.

In the meantime:

* Don't force feed your dog: This can be dangerous.

* Secure your garbage: This will prevent her from eating potentially harmful items.

* Offer small, frequent meals: This can encourage your dog to eat if she is struggling with a full bowl.
