Can dogs eat banana?
Most dogs love bananas! And they are safe to eat if fed in their natural, unmodified form. This sweet treat is perfect as a snack, training aid, meal topper, or even as part of a puzzle feeder to keep boredom away when you are not there to play with your dog. This versatile, cheap fruit can add joy and variety to your dog's diet.
Are bananas good for dogs?
Bananas are packed with nutritional value. They contain vitamins, like vitamin C, which acts as an antioxidant to reduce the inflammatory load in the body, especially helpful in sick or older animals.
Bananas are a rich source of fibre, which helps them poop and improves their gut health. A dog's digestive tract is linked to their whole health, so using fruits like bananas to promote diverse, strong gut health is becoming increasingly important in preventative healthcare.
How much banana can a dog eat?
Depending on the size of your dog, they can eat anywhere from a quarter (for small dogs) up to around one and a half bananas (large breed dogs), one to two times a week as part of a balanced diet.
When first feeding a banana, feed a teaspoon-sized amount to check that your dog enjoys the flavour, and doesn't have any side effects from eating the banana. You can then increase the amount slowly over a few weeks.
How should I prepare bananas for dogs?
Feeding a whole banana is a choking hazard, so spend a few minutes preparing the banana so that it can be enjoyed safely by your dog.
Dogs can eat bananas sliced, chopped or mashed. Different textures add variety and interest to their diet and can increase appetite in picky eaters. A mashed banana that’s then frozen on a lickimat or Kong toy provides a fun, enriching way to play with food.
Can dogs eat banana peels?
No, feeding banana peels isn't a good idea. They are tough to digest, and this can lead to gastrointestinal pain or upset. Banana peels are bitter in taste, so most dogs won't enjoy eating them, especially when compared to the sweet taste of the banana fruit!
Can dogs eat banana bread?
Sadly, your dog cannot share your banana bread. Whilst they would no doubt find it a tasty snack, it could be harmful to their health.
Bread swells when eaten, and in dogs can cause gastrointestinal bloat, blockage or diarrhoea. Banana bread can contain ingredients such as chocolate, salt, or xylitol, which are toxic to dogs if ingested. Play it safe and feed the banana in its natural form only.
What should I do if my dog eats too much banana?
If your dog has overindulged in bananas, they will likely have symptoms of diarrhoea and bloating. This usually lasts a day or so, and whilst uncomfortable, is self-limiting, so no treatment is needed outside of feeding a bland diet for a few days to help the gastrointestinal tract settle down again.
If your dog has eaten more than one whole banana, including the peel, then you should contact a veterinarian for advice, as they may recommend making your dog sick to avoid the peel getting stuck in your dog's digestive tract.
What are the signs of a banana allergy?
Allergic reactions to bananas are rare. There are no published scientific reports of banana allergies in dogs. If after eating a banana you notice vomiting, facial swelling, collapse, or difficulty breathing, these are signs of anaphylaxis and need urgent veterinary attention.
Can cats eat banana?
Bananas are safe for cats to eat, but they’re rich in sugars, so we only recommend a small amount.
Are bananas good for cats?
Bananas have lots of health benefits. They are a rich source of potassium, which is important in heart health. Their high fibre content promotes gut motility and acts as a prebiotic, which helps maintain your cat's microbiome.
How much banana can a cat eat?
Around a third of a banana is enough for a cat to enjoy per week. No more than 10% of your cat's diet should be made up of treats, and bananas are considered part of the treat allocation.
How should I prepare a banana for my cat
You can prepare it any way you want as long as it’s 100% banana. They can enjoy bananas sliced, diced, mashed or frozen. By breaking the banana up into bite-sized pieces for your cat, you reduce the risk of them choking on larger pieces.
Not all cats will enjoy bananas, so if your cat isn't interested, that's ok! Just look for other safe fruit and veg to feed instead. Just like people, cats are individual, with different preferences based on their personalities and tastebuds.
Can cats eat banana peel?
No, it's bitter in taste and fibre-dense. The fibre density is likely to create gastrointestinal issues like constipation and abdominal (belly) pain.
Can cats eat banana bread?
No, banana bread is not a good food option for cats. The banana is mixed with other ingredients such as sugar or chocolate which can lead to bloating or digestive upset. Some baking ingredients, such as xylitol, are toxic to cats, so feeding plain bananas is always the safest option.
What should I do if my cat eats too much banana?
Try not to worry too much. If your cat eats too much banana, the sugars can create an upset tummy, diarrhoea or loose stool, lack of appetite, and sometimes vomiting. This usually only lasts for 24-48 hours and does not need veterinary treatment.
What are the signs of a banana allergy in cats?
Banana allergies have never been reported in cats, which makes the risks very low. If you were to see signs such as facial swelling, vomiting, diarrhoea, or collapse soon after your cat eats a banana, this could indicate anaphylaxis. This is a medical emergency, and you need to go to the vet clinic straight away.
