Food safety
Can dogs eat very salty food?
No — don't give this
Large amounts of salt cause serious problems. Salt dough decorations and swallowing lots of seawater are the usual causes.
Being honest about this
Dogs differ, and amount matters — a crumb of something rich is not the same as half a packet. Treats of any kind should stay under a tenth of what your dog eats in a day. If you're unsure, your vet would far rather take the call.
