Why is this the verdict?
Most adult dogs and cats have some degree of lactose intolerance, because production of the enzyme lactase (needed to digest milk sugar) naturally decreases after weaning. This isn't a toxicity — it's a digestive issue that causes gas, bloating, abdominal pain, and diarrhea in proportion to the amount consumed and the animal's individual tolerance.
An occasional small sip of milk rarely causes serious problems, but offering milk regularly, or in large amounts, tends to cause real gastrointestinal discomfort. There's no nutritional need for milk in the diet of adult dogs or cats.
