A little salt in dog food is normal and necessary — the danger is a large amount at once, which can cause sodium poisoning.
How much is safe?
The risk comes from very salty human foods (chips, jerky, cured meats, broth), homemade salt dough, and gulping seawater at the beach. Always keep fresh water available and don't let pets gorge on salty snacks.
What happens if a dog eats too much?
Watch for heavy thirst and urination, vomiting and diarrhea, wobbliness, and in severe cases tremors or seizures as too much sodium affects the brain.
⚠ What to do if your dog ate salt
Call your vet or a poison line (ASPCA 888-426-4435 · Pet Poison Helpline 855-764-7661). Don't try to fix it by withholding water — rapid correction can be dangerous, so let the vet guide you.

Frequently asked questions
How much salt is too much?
It depends on size — a small dog or cat needs far less to be affected. A big one-off salty binge is the usual trigger.
Is homemade salt dough dangerous?
Yes — salt-dough ornaments are very high in salt and a common cause of poisoning; keep them well away.
Can dogs drink seawater?
Gulping seawater can cause salt poisoning — bring fresh water to the beach and offer it often.
