Dog Diarrhea - Common Causes and Solutions

1. Poor diet or unsuitable food

An inappropriate diet is one of the most common causes of diarrhea when it comes to dogs. Often, we are the reason - table scraps or too many treats can upset your dog’s digestion.

Solution & prevention: Choose high-quality food or, when feeding BARF, make sure your dog gets the correct balance of nutrients. Keep an eye on your dog during walks to prevent them from eating things they shouldn’t
What to have on hand: Keep Poop Good and Gastrofix in your dog’s first-aid kit for a quick digestive reset when needed

2. Allergies and sensitive digestion

Dogs can be allergic or sensitive to certain proteins (such as chicken, fish or dairy ingredients), grains or soy. This often shows as consistently soft stools or recurring diarrhea.

Solution: Remove the potential allergen, limit treats and choose hypoallergenic food
Long-term support: For dogs with sensitive digestion, PROBIO FORTE is ideal for daily care of the gut microbiome and helping maintain firmer stools

3. Viruses and recovery after treatment (e.g. antibiotics)

Digestive issues caused by viruses can affect any dog from time to time. Medication and antibiotics can also significantly disrupt the gut.

Solution: Feed an easily digestible diet (such as cooked rice with carrots and lean meat) and support the digestive system with Gastrofix
What helps: Gastrofix is ideal for helping the digestive system get back on track after illness or antibiotic treatment

4. Stress

Competitions, shows, fireworks or moving - stress can trigger digestive reactions in dogs, just like in humans.

Solution: Stress-related digestive upset can be quickly supported with Gastrofix
