Understanding the Risks: Why Some Dog Foods Are Not Recommended by Vets
Not all dog food is created equal. Some products are loaded with fillers, artificial preservatives, and low-quality meat by-products that provide little to no nutritional value.
Common Harmful Ingredients Found in Low-Quality Dog Food:
- BHA/BHT (chemical preservatives)
- Artificial dyes (Red 40, Yellow 5)
- Meat by-products from unspecified sources
- Excessive corn, soy, or wheat fillers
Veterinarians have linked these ingredients to health issues like obesity, skin allergies, gastrointestinal disorders, and even heart problems.
Expert Insight: Dr. Lisa Freeman, a veterinary nutritionist at Tufts University, notes, “Many cases of canine dilated cardiomyopathy have been traced back to grain-free diets high in legumes and low in essential nutrients.”
