What if a dog eats salt?

Dogs can eat some salt; moderate intake supplies electrolytes and maintains fluid balance, blood pressure, acid-base balance, and nerve and muscle function. However, too much salt easily causes tear stains and eye discharge, especially in Bichon and Teddy.

Long-term excess salt causes heavy hair loss and kidney burden. A one-time large amount may cause salt poisoning: thirst, excessive drinking, vomiting, dehydration, seizures, even coma.
