Heart disease is noticeably increasing in dogs and cats. As knowledge about animal health grows, the importance of nutrition is also becoming increasingly important.
HenArt, a Dutch pet food company, develops food solutions specifically for animals with health challenges. Our plant and insect protein-based products are formulated to provide complete nutrition—with the goal of supporting overall health, especially the heart.

The silent threat: Heart disease in pets

Heart disease in dogs and cats can manifest in various forms, including congenital heart defects, dilated cardiomyopathy (DCM), and valvular heart disease. Early symptoms may be subtle, such as lethargy, coughing, or a decrease in appetite, making it critical for pet owners to be vigilant. Dogs such as Doberman Pinschers and Boxers are particularly susceptible to DCM, while certain breeds like Cavalier King Charles Spaniels often face mitral valve disease.

The Symptoms

Recognizing the signs of heart disease can be challenging, but several key indicators can alert pet owners to seek veterinary care:

Lethargy

Unusual tiredness or a lack of desire to exercise can be the first signs.

Coughing or Wheezing

Breathing problems, especially after exercise or at rest, may indicate fluid in the lungs.

Weight Loss

If the animal's appetite decreases or it visibly loses weight, this should be taken seriously.

Fainting

Short-term unconsciousness is a clear warning sign and requires veterinary examination.

Rapid Breathing

Noticeable panting or shortness of breath – even without exertion – may be related to heart failure.

Diagnosis and treatment

If heart disease is suspected, the veterinarian has various diagnostic options available, including X-rays, echocardiograms, ECGs or blood tests.
Depending on the findings, an individualized treatment plan is developed, tailored to the type and severity of the disease. Therapy may include various measures:

Medications

They support heart function, help regulate blood pressure and counteract fluid retention.

Surgery

In certain cases, surgery may be necessary, for example to correct congenital malformations.

Dietary Changes

Feeding plays a central role in treatment – ​​it supports the heart and contributes to the general stabilization of health.

The Importance of Diet in Managing Heart Disease

In addition to medical treatment, nutrition plays a key role in heart health. Food high in saturated fat can increase the risk of obesity and high blood pressure—both factors that contribute to heart problems. Conversely, a balanced diet with an appropriate protein content not only supports treatment but can also help prevent heart disease.

HenArt's Approach to Nutrition

At HenArt, the health of dogs and cats is our top priority – and with it, the question of what ends up in their bowls. The specially developed food recipes rely on modern plant and insect protein sources. They provide all the essential nutrients and help avoid risks associated with conventional animal proteins.

Plant-Based Diets

Studies suggest that a plant-based diet can have health benefits for dogs and cats, including reducing inflammation, lowering the risk of obesity, and providing important nutrients. Ingredients like lentils, chickpeas, and sweet potatoes not only provide fiber and essential amino acids, but also promote heart health by contributing to weight control.

Insect proteins: The future of pet food

Proteins from insects – especially mealworms – are becoming increasingly important in animal nutrition. Not only do they boast high levels of omega-3 and omega-6 fatty acids, but they can also support heart function, contribute to skin and coat health, and have a positive effect on cholesterol levels. At the same time, insects are considered a particularly sustainable source of protein – an aspect that is becoming increasingly important for many environmentally conscious pet owners.

The HenArt Eggshell Membrane®

HenArt relies on a special ingredient that is still rarely found in pet food: eggshell membrane. It contains valuable components such as collagen, glucosamine, and chondroitin sulfate – known for their positive effects on joint, heart, and metabolic health.

The ingredients of the eggshell membrane can:

• Support joint function, which is particularly important for animals with heart problems, as mobility and circulation are often related,
• Reduce inflammatory processes in the body that can increase the risk of heart disease,
• Improve nutrient absorption so that the feed is optimally utilized.

What to do – and what not to do

Dos

✅ High-quality food

It's best to choose brands that focus on wholesome and balanced recipes – ideally with plant or insect proteins.

✅ Monitor weight

Regular weighing helps to detect and counteract obesity early.

✅ Exercise

Age-appropriate activity supports the circulation and keeps the heart fit.

✅ Regular Check-ups

Health checks at the vet – preferably once a year – can help identify problems early.

✅ Watch for symptoms

Those who remain alert often notice small signs before they become serious symptoms.

Don'ts

❌ Overfeed

Overfeeding is a common cause of obesity, which puts strain on the heart.

❌ Ignore symptoms

If there are any changes in behavior or fitness, it is better to get it checked out early.

❌ Switch diets abruptly

A gradual change protects the digestive tract and avoids stress.

❌ Give table scraps

Many foods that are safe for humans can harm animals, so it's best to stick to special pet food.

The science behind HenArt's nutrition concept

In veterinary medicine, awareness is growing of the significant impact nutrition can have on health. A study published in the Journal of Veterinary Cardiology shows that targeted nutritional management plays a crucial role in dogs with a genetic predisposition to DCM (dilated cardiomyopathy). Recipes that avoided controversial ingredients such as high amounts of peas, lentils, or potatoes and instead contained more high-quality protein had a particularly positive effect.

This is precisely where HenArt comes in: The recipes are developed based on current research and in close collaboration with veterinarians. The use of plant and insect proteins creates complete food mixtures that are specifically tailored to the needs of dogs and cats – including their heart health.

Conclusion

Heart disease is one of the most common health problems in dogs and cats – but well-informed patients and early intervention can make a big difference. A better understanding of symptoms, causes, and, above all, the influence of diet plays a crucial role.

With innovative feed concepts based on plant- and insect-based proteins, HenArt offers an alternative that is not only nutritious but also specifically supports heart health. The combination of a high-quality protein source and functional ingredients such as the HenArt Eggshell Membrane® makes this mealworm feed a well-considered choice for pet owners who value both health and sustainability.

Anyone who wants to consciously shape their pet's diet will find in HenArt a partner with the aim of developing scientifically sound yet practical solutions – for a healthy, active life for our four-legged companions.
