Baking soda is sodium bicarbonate. Baking powder combines baking soda with an acid of some kind, usually cream of tartar, sodium aluminum sulphate or calcium acid phosphate, or a combination of the three. If your dog eats a large amount of either of these powders, he can suffer from electrolyte changes, muscle spasms and congestive heart failure. Keep baking soda and baking powder out of your dog's reach. If you spill some on the floor, clean it up immediately. bro, id call the vet. peace
