  1. My dog, Milo, loves anything with banana in it. Banana is high in potassium, vitaminB6, fiber, magnesium, vitamin C. It reduces gastrointestinal issues, helps the body to produce protein and absorb vitamins.

  2. I am fostering a dog he is a year old approximately he had to have his tail amputated and he was starved nearly to death. He look like lab/ Airedale’s he is wonderful but has digestive problems bananas he loves and it is helpful in the diarrhea problem he is eating 5 small meals a day plus treats. He is improving slightly he gets 1 bananas a day. He has to go back to the shelter Monday I am sending him with his food and bananas and his treats. I just hope all goes well. He loves coconut water as well.

  3. My boy loves bananas. We often share a banana after work / daycare in the evening as part of our special time together. I don’t think I‘ve eaten a banana alone in over 3 years 🙂

  4. When I have medicine or worming tablets etc to give my dogs, I push them into a piece of banana and they gobble them willingly!

  5. My 15-month old lab, Archie. Has had food sensitivity issues as well as gut problems. For the last 7 months he has eaten a raw diet and takes supplements as well. There are very limited kinds of treats I can buy for him, so I make a lot of his treats. One favourite is frozen fruit smoothie treats. I blend organic blueberries, pears, and bananas with unsweetened organic applesauce and then freeze them in the shape of paws and bones. He gets 2 a day, so a batch will,last about 2 weeks. I also bake treats made of banana, coconut flour, and pumpkin. I make them into little balls and put them in his KOng Wobbler. He just loves them.

  6. Thank you for this, I think the general rule is the same for people-everything in moderation.
    I have a 16 year old lab, he will share a small portion with me of Banana, he gets cramps so I give him banana for the magnesium and potasium.
    It might be once a month, when he was younger a little more often.
    But he may spit it out, so its an infrequent treat these days.
