Benefits of asparagus for dogs

Asparagus is very low in fat (0.12%) and sugars (1.9%), and very rich in fiber (2.1%) and vegetable protein (2.2%) [1]. They stand out for their anti-diabetic, hypolipidemic, and antioxidant properties [2]. Some of their essential nutrients are:

  • Fiber, both soluble and insoluble, the first is responsible for reducing cholesterol and blood glucose, thus helping to prevent obesity and cardiovascular diseases, as well as helpful in the control of diabetes. The second regulates intestinal transit, protecting the digestive system [2, 3]. In cases of constipation, it may be useful to include asparagus in your diet because it accelerates intestinal transit.
  • B-group vitamins, such as folic acid, are important for the synthesis of proteins and DNA, which also provides benefits in pregnant dogs by decreasing the development of spina bifida and anencephaly [4]. It also contains vitamins C, E, and K.
  • Minerals, such as potassium, calcium, magnesium and iron, are found in a high percentage in the upper section of the stem, near the tip [1]. Very notable is the potassium content, which helps control blood pressure [5] and, together with the presence of an amino acid called asparagine, increases diuresis, beneficial in animals with kidney damage or fluid retention [6].
  • Flavonoids and phenolic compounds, with antioxidant and anticarcinogenic effects. [7].

Don't forget that whenever you introduce a new food to their diet, you should give them small amounts and observe how their body responds, and from there gradually increase the amount.

How to give asparagus to my dog?

Avoid giving your dog raw asparagus, so get your stove going. Follow our instructions to give it to your dog in a safe way:

  • Wash the shoots carefully and remove the bottom part of the asparagus, as it is fibrous and may be difficult for them to chew.
  • Cut the stalks into small, bite-sized portions for easy swallowing.
  • Boil or steam them until they are soft and tender, thus reducing the risk of obstruction and facilitating chewing. Additionally, cooking increases the antioxidant effect of asparagus [8].

Now that you have asparagus ready to offer to your furry friend, here are some ideas on how to incorporate it into his diet:

  • Mixed into their usual food.
  • In the form of a smoothie, blend with other vegetables, fruits and natural yogurt.
  • As an ingredient in a broth, along with chopped chicken and spinach, it will be a healthy soup that you will love in winter.

Can they be dangerous?

Asparagus in the form of tender stems are not toxic, but if we let the asparagus mature, it turns into ferns with poisonous red berries, both for dogs and humans, which can cause side effects such as vomiting, diarrhea or severe stomach pain.

So, if you grow these vegetables, put a fence around them to keep your pet away and avoid problems from poisoning.

Giving raw asparagus carries the risk of getting stuck and choking, especially in small dogs, because it is tough and stringy, and most dogs will gobble whole mouthfuls without chewing.

What should I do if my dog eats too much asparagus?

If you have given asparagus to your dog, you may have noticed that his urine has a more unpleasant odor. This is due to the presence of asparagusic acid, a compound containing sulfur, exclusive to this vegetable, which when metabolized is transformed into methanethiol, a molecule that confers this bad odor to the pee [9].
