Can a Chihuahua eat kiwi?
Yes, occasionally, peeled and in small amounts.
How much: 1 small piece with no skin or seeds, once a week at most.
Why
Kiwi provides vitamin C and fiber. The skin and the high oxalate content can upset his stomach: peeled and in small amounts, it works as an occasional treat.
Kiwi 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.
