Can my dog eat chow mein?

No.

Soy sauce makes it very salty, and onion, garlic and spring onion are standard. A mouthful isn't an emergency.

Already ate it?

If they ate itA mouthful is fine. A whole plate: make sure fresh water is available and call your vet, especially for a small dog.
Watch forVomiting, extreme thirst or diarrhoea within hours (salt); weakness, pale gums or dark urine 3–5 days later (onion and garlic).

Thinking of giving it?

WhySoy sauce is one of the saltiest things people commonly feed dogs by accident.
