Benefits of feeding Plantain to dogs


Dogs need various minerals to maintain their health. Puppies need these minerals for growth and development. While some of these minerals can be supplemented in the event that a dog is suffering a deficiency.

Feeding the right amount of food to your dog can ensure that they are always replenished.

Feeding plantains to your dog will provide the following minerals and together with a balanced diet save your dog from suffering from the listed medical conditions.

Potassium, Sodium and Magnesium

These minerals are very important in the body of a dog as dogs need them for muscle contraction, cell signaling, and nerve impulse transmission. The daily minimal potassium supply for dogs should be 1g, 150g for magnesium, and 200mg for sodium according to

Deficiency in these minerals can lead to life-threatening conditions such as Hypokalemia.

Hypokalemia is a condition in dogs that is a result of low potassium in the dog’s blood. Hypokalemia can have a very adverse effect on the dog’s cell functioning, tissue, and organs especially if left untreated for a long time.

If you observe any signs of hypokalemia you should consult your vet immediately.

Hypokalemia affects three muscles severely, these are skeletal muscles, cardiac muscles, and neurological. While some dogs manifest symptoms there are dogs that do not show symptoms at all.

Hypokalemia can manifest itself suddenly while at the same time it can also take time before it manifests.

The following are some of the symptoms of a dog suffering from hypokalemia.

  • Lethargy
  • Vomiting
  • Loss of appetite
  • Weight loss
  • Constipation
  • Muscle pain
  • Weakness
  • Unusual gait
  • Unwillingness to walk or move
  • Difficulty breathing because of paralysis in respiratory muscles
  • Increased thirst or urination
  • Arrhythmia
  • Curving head down to the chest

It is therefore very important to make sure your dog has the recommended daily intake of potassium.

Overfeeding potassium can also lead to a condition known as hyperkalemia. This is a condition whereby the dog’s blood has a lot of potassium levels, both hyperkalemia and hypokalemia are associated with the kidney.

When dogs are not urinating as much as they should kidney does not remove excess potassium and when they are urinating more than usual they lose more potassium well aside from a potassium deficient diet.

Calcium and Phosphorus

Calcium and phosphorus are very important in the development of healthy and strong bones and teeth. The daily recommended calcium and phosphorus intake are 1g for calcium and 0.75 g for phosphorus.

Calcium deficiency leads to hyperparathyroidism, a condition that is associated with major bone loss, skeletal abnormalities, and pathological fractures.

Too much calcium on the other hand can also lead to skeletal abnormalities more so in large dog breeds.

Deficiency of vitamin A will cause skin lesions, corneal disorders, anorexia, ataxia, respiratory ailments, conjunctivitis, and increased susceptibility to infection.

While excessive vitamin A feeding will cause joint pain, dehydration, imbalance in bone remodeling processes, and central nervous system depression.

It is very rare to find a dog that is suffering from Vitamin A deficiency since a dog needs about 379 µg of vitamin A per day based on this source.

Vitamin B6

Vitamin B6 is also very important in the dog’s diet since it helps with gene activation, glucose generation, niacin synthesis, nervous system function, immune response; hormone regulation, and red blood cell function.

Deficiency signs include convulsions, Anorexia; muscle twitching, anemia in adult dogs, and weight loss in puppies.
