On the negative side, introducing new foods too quickly or feeding your pup an inadequate amount of essential vitamins and minerals can lead to health issues such as malnutrition, digestive upset, and even allergies.


A few dandelions can act as a diuretic. If you allow your dog to eat dandelions, be prepared to take them outside more often.
