Can a Chihuahua eat milk?
⚠️ In moderation
Better to avoid. Lactose intolerance is common.
How much: If you really want to, one teaspoon once in a while. Many dogs get diarrhea from milk.
Why
Most adult dogs lose the lactase enzyme and don't digest milk well.
Milk in a Chihuahua's diet
Keep in mind how tiny the portions are for this breed: an adult Chihuahua eats roughly 1 to 2.3 ounces (25-65 g) of food a day depending on his weight, and treats shouldn't go over 10% of his daily calories. That's only a small fraction of an ounce. What looks like "a little bite" to us can be half a meal for him.
