Buying Guide
Sensitive Stomach vs. Food Allergy
Sensitive stomach (intolerance) typically causes GI symptoms alone. Food allergies cause GI and skin symptoms. This distinction guides treatment: intolerance may resolve with a more digestible formula; allergies require allergen elimination.
Fat Content and Digestive Sensitivity
High-fat diets trigger vomiting and diarrhea in dogs with sensitive stomachs. For sensitive medium breeds, choose formulas with fat content below 15% (dry matter basis).
Fiber Balance for Stool Quality
Both too little and too much fiber can cause loose stools. Ideal fiber for digestive health is 3-6% crude fiber. Soluble fiber (beet pulp, psyllium) slows gut transit and improves stool consistency.
Meal Size and Frequency
For medium breeds with sensitive stomachs, smaller more frequent meals are easier to process. Split the daily ration into three smaller meals. Avoid feeding immediately before or after vigorous exercise.
Frequently Asked Questions
What causes chronic loose stools in medium breed dogs?
Common causes include dietary intolerance, parasites, bacterial imbalance, IBD, and stress. Start with a fecal exam to rule out parasites, then try a highly digestible LID formula.
Is rice and chicken good for a medium dog with sensitive stomach?
Plain boiled chicken and white rice is an excellent short-term bland diet for acute GI upset. However, it is not complete and balanced for long-term use.
Can stress cause digestive problems in medium breed dogs?
Yes. The gut-brain axis is well-documented in dogs. High-stress environments or separation anxiety can trigger vomiting and diarrhea. Address both the diet and underlying stress.
Are probiotics helpful for medium breed dogs?
Yes, probiotics with strains like Enterococcus faecium SF68 have proven efficacy for acute and chronic diarrhea in dogs.
