Why are lentils Bad for Dogs? 

Although lentils are endowed with a rich nutritional profile, they have some downsides. However, it is possible to overcome these adverse reactions with certain precautions. Here are the downsides of serving lentils to your dogs:

  1. Lentils come with a low digestibility rate

Serving lentils in larger quantities can slow down the digestive process in dogs. Hence, they have to be served in moderation to avoid:

  • Gassiness
  • Stomach upset
  • Diarrhea
  • Nausea

For the same reason, you have to introduce lentils slowly to your dog if you have just begun to feed him. 

  1. Uncooked lentils contain lectin

Raw lentils contain lectin. Lectin is a glycoprotein meant to induce gastrointestinal absorption. However, they come with the risk of encouraging bacterial growth in your canine’s stomach. Although your canine’s gut is capable of breaking down lectin, this reaction can lead to gassiness in dogs. Alternatively, when foreign molecules like lectin are not broken down completely, your dog’s immune system identifies it as a foreign body and begins to attack it. Consequently, your dog can experience the below-mentioned symptoms:

  • Gut lining inflammation 
  • Gastroenteritis signs like vomiting or diarrhea 
  • Rashes 
  • Joint pain 

Therefore refrain from feeding large amounts of uncooked lentils. 

Further, you must ensure to prepare the lentils properly, soaking them completely to remove dryness and cook thoroughly. 

  1. Lentils contain phytates leading to a mineral deficiency

The presence of the substance phytates in lentils is known to bind with minerals such as calcium, iron, and zinc, preventing their absorption. A lack of absorption of vital minerals ultimately leads to mineral deficiency in dogs.

However, soaking lentils overnight aids in the partial removal of these substances. This is also why legumes shouldn’t constitute much of your canine’s diet. 

  1. Lentil soup is toxic to dogs

Refrain from feeding canned soups containing lentils to your dog. This can be toxic to your pet as it contains garlic or onion. In addition, you have to take care you do not feed lentils enriched with spices or salt as a preservative. 

  1. Do Lentils Cause Heart Disease in Dogs?

DCM is the short form of Dilated Myocardiopathy. This is a cardiac condition resulting from widening cardiac chambers in dogs. Consequently, the affected dog’s heart finds it challenging to pump blood out of the heart leading to congestive heart failure. The actual cause for DCM is still unknown, but certain factors like genetics, breed predisposition, and possibly nutritional links are being investigated. 

It is suspected that there is a link between grain-free diets containing peas or lentils and DCM. However, there is no evidence to support this claim. Further, the connection between DCM and nutrition is suspected to be due to taurine and carnitine deficiency in dog foods. Some breeds prone to DCM  include Golden Retrievers, Boxers, Great Danes, Dobermans, and Labradors. Dogs affected by DCM often showcase early signs. These include:

  • Intolerant to exercises
  • Excessive panting while breathing
  • Coughing
  • Distended belly
  • Weight Loss 
  • Lethargy 
  • Fainting episodes
