How do you know your dog ate hamster?

It's important to remember that I am a language model and I do not have any personal experiences or knowledge of real-world events like pets or their behavior.

If you are concerned that your dog might have eaten a hamster, here are some signs to look for:

* Visible evidence: If you see pieces of hamster fur or parts of the hamster in your dog's vomit or feces.

* Behavioral changes: Your dog may be acting lethargic, vomiting, having diarrhea, or showing signs of abdominal pain.

* Missing hamster: If your hamster is missing and you suspect your dog may have eaten it.

If you suspect your dog has eaten a hamster, it's important to contact your veterinarian immediately. They can provide the best advice and treatment based on your dog's individual situation.

Please note: It is never recommended to leave your dog unsupervised with small animals like hamsters.
