Symptoms to Watch For
🐕 In Dogs
- Extreme thirst and excessive urination

- Lethargy, "walking drunk," and muscle tremors
- In serious cases: seizures, kidney damage, death
🐈 In Cats
- Sodium ion poisoning
- Vomiting, lethargy, and "walking drunk"
- Muscle tremors
- In serious cases: seizures
What to Do If Ingested
- Call a veterinarian or poison hotline immediately for guidance.
- Offer water only as directed — too much too fast can be dangerous.

Frequently Asked Questions
Frequently Asked Questions
How much salt is dangerous?
Large amounts of salt — from rock salt or deicers licked off paws, salty playdough, or a lot of table salt — can cause sodium ion poisoning. Pets are small, so the toxic dose is reached more easily than in people. Call a vet with the source and amount.
Is sidewalk deicing salt dangerous to pets?
Yes. Deicing salt on sidewalks can irritate paws and, if licked off or ingested, cause sodium ion poisoning. Wipe your pet's paws after walks, and call a vet if they ingest deicer or show excessive thirst, vomiting, or tremors.
Should I give my pet lots of water after salt ingestion?
Not without veterinary guidance. Rehydrating too quickly after high salt can cause dangerous fluid shifts in the brain. Call a vet or poison hotline first and follow their instructions on water and treatment.
