Can dogs eat salty snacks?
Not recommended. A few salty snacks are unlikely to cause salt poisoning in a healthy dog with fresh water, but salty foods are generally not good for dogs, especially those with heart disease. Eating a lot can cause thirst, vomiting and worse.

Why
Salty food in moderation should not cause salt toxicity, but too much salt can lead to fluid retention and, in large amounts, salt poisoning. Small dogs with health issues are more at risk when fresh water isn't available. Dog foods are best served without added salt or seasoning.
Signs to watch for
- Strong thirst and peeing a lot
- Vomiting, often within a few hours
- Diarrhoea
- Wobbliness, tiredness
- Tremors or seizures
What to do
If your dog ate a large amount of salty snacks, contact your vet or a pet poison helpline. Note what and how much was eaten. Fresh water should always be available.
How to give it
Better not to share. If you give people food, serve it plain, without salt or seasoning.
Questions and answers
Does my dog need water after salty food?
