Digestive problems in dogs


Digestion in dogs

Digestive problems in dogs range from diarrhoea and vomiting to flatulence and inconsistent stools, often triggered by food, stress or a disturbed gut flora. If the symptoms persist, a veterinary assessment is advisable. Gut-friendly nutrients such as Jerusalem artichoke and acacia fibre as well as easily digestible food can meaningfully support the normal digestive function.

Diarrhoea and soft faeces » Widespread

Digestive problems, such as diarrhoea and soft faeces, are common problems in dogs that can be a burden for owners and their four-legged friends. The causes are many and varied, but often lie in the dog's diet. Dogs are naturally carnivorous to around 70 to 80 per cent, and a diet that strays too far from this biological basis can cause digestive problems.

However, there are other possible causes, such as an acute gastrointestinal infection caused by viruses or bacteria, stress, anxiety, pain, excitement, allergies and intolerances or medication.

More rarely, gastrointestinal parasites such as worms, giardia or salmonella as well as inflammation of organs such as the pancreas, tumours, hormonal diseases or poisoning can be a cause.

It is important to emphasise that serious illness or poisoning must always be treated by a vet. To reassure dog owners: Diarrhoea or soft faeces usually have relatively harmless causes.

Nutrition & Food Quality

Diet plays a central role in a dog's digestion. Dogs are naturally carnivores. If they are consistently fed foods high in carbohydrates, fillers, or artificial additives, this can impair their natural digestive function. Poor protein sources or unclear ingredient declarations are additional risk factors. Dry foods with a low moisture content, in particular, can challenge digestion and lead to the food staying in the intestines for longer.

Food Intolerances & Allergies

Food intolerances and allergies are common in dogs. They are often triggered by certain protein sources, grains, or additives. Disturbed intestinal flora—for example, after a change in diet or stress due to illness—can also lead to digestive problems. Since the intestines influence a large part of the immune system, disorders here often affect general well-being.

Influence of medications

Certain medications, such as antibiotics or worming treatments, affect not only harmful but also beneficial bacteria in the digestive tract. Administration of such medications can lead to temporary digestive disturbances. Gently stabilizing the intestinal flora is then advisable.

Other triggers

Stress, changes in environment, parasite infestation, or eating unsuitable foods can also temporarily impair digestion. Especially with young, older, or sensitive dogs, a veterinarian should always be consulted if problems persist for a long time.

What dog owners should pay attention to

  • Pay attention to sudden or prolonged changes in stool (color, consistency, frequency).
  • Observe for other symptoms such as vomiting, fever, or lethargy.
  • Provide an adapted, high-quality diet and pay attention to the tolerance of new food ingredients.
  • Always seek veterinary advice if symptoms persist or if you are unsure.

Importance of intestinal flora and nutrition

An intact intestinal flora is important for the dog's digestion and immune system. After stress such as medication or diarrhea, a balanced diet can help restore balance. Carefully selected and natural micronutrients and a customized diet support normal digestive function and well-being.

Note on observation and prevention

Dog owners should carefully monitor any changes in their dog's behavior, appetite, or well-being. Prompt veterinary consultation is particularly advisable in cases of persistent diarrhea, bloody stools, fever, or other symptoms of illness. Regular checks of the dog's general condition, adjusting exercise, and providing fresh water are also important components of a dog's health. Responsible handling contributes to maintaining the dog's well-being and zest for life in the long term.

You and your dog: Every day with your dog holds small adventures and big moments. With patience, care, and an open mind for your four-legged friend's needs, you strengthen your bond and provide security. This ensures that your life together remains full of trust, joy, and shared discoveries—for a wonderful time together.
