salt can be given to dogs to increase the platabilty of the dogs food but always remember that giving anything in excess is not good for them same goes for salt too.

No, most likely human food dont have high salt levels.

no actually we are not giving him salt, but by mistake he ate food which was falken on floor. so i was concern that it wont effect his health

Salt should be limited in your dog's diet. Excessive salt intake may lead to salt poisoning or water deprivation in dogs, which can cause vomiting, diarrhea, vomiting and seizures.

A big noooo... you can give him but very small amount as It will not harm your dog

thank u all. I'll take care of this from next time
