Bananas and dogs: the flesh is a treat, the peel is an obstruction risk
Safe in moderation
Peeled ripe banana in small pieces can be given occasionally; the peel is the part these sources tell you to keep away from the dog.
Plain, and not much of it.
Yes, in moderation, once it is peeled. PetMD and the AKC treat ripe banana flesh as an acceptable occasional dog treat and single out the peel as the part to withhold, because it is hard to digest and can obstruct. Banana bread, pudding and sugared banana chips are separate foods and are not covered by that verdict.

If your dog has already eaten bananas
Offer only a small plain amount; stop if gastrointestinal upset occurs. For prescription diets or medical conditions, ask the veterinarian first.

Which form of bananas the sources actually cleared
Banana is one of the few foods in this batch where the unsafe part is not a pit or a bone but the wrapper, and dogs are perfectly capable of eating a banana whole off a counter. The peel is not described as poisonous; it is described as indigestible and capable of causing an obstruction, which is a surgical problem rather than a toxicological one. Ripeness matters to the sources only in that the cleared form is the ripe flesh.
Preparing bananas for a dog
Peel it, then break or slice the flesh into pieces sized for your dog. Bananas are soft enough that the choking risk is lower than with a firm fruit, so the practical constraint is calories rather than mechanics: a banana is a dense, sugary item next to a carrot stick, and a whole one is a large share of a small dog's treat allowance for the day.
What actually goes wrong
- sugar and calorie load
- peel can be hard to digest or obstruct
Two risks, and they are different in kind. The first is the sugar and calorie load of the flesh, which is a routine over-feeding problem. The second belongs to the peel: an object that does not break down and may lodge. A dog that has swallowed a peel is a call to a veterinarian for advice, not a wait-and-see, because the concern is mechanical.
How much counts as too much
All treats combined should generally stay within 10% of daily calories for a healthy adult dog in ideal body condition; individual needs vary.
The table below is the WSAVA reference allowance, printed as published. It is not a portion of bananas: it is the total treat-calorie ceiling that everything given outside meals has to fit inside. Average healthy adult dog in ideal body condition. A veterinary team should set the individual dog's daily energy requirement.

|---|---|---|
| 2 | 4.4 | 14 |
| 4 | 8.8 | 24 |

What these sources do not settle
Neither source states a number of banana slices for a given dog. Where a page online gives you 'half a banana for a medium dog', that number came from the writer, not from the guidance.
