Why Most Dogs Are Lactose Intolerant<\/h2>\n

Puppies produce plenty of lactase<\/strong> \u2014 the enzyme that breaks down lactose in their mother’s milk. After weaning, lactase production naturally decreases<\/strong>. This means most adult dogs struggle to digest the lactose in cow’s milk, leading to uncomfortable symptoms.<\/p>\n

Symptoms of Lactose Intolerance<\/h2>\n

Symptoms typically appear within 30 minutes to 12 hours<\/strong> after drinking milk:<\/p>\n

    \n
  • Diarrhoea (most common sign)<\/li>\n
  • Excessive gas and bloating<\/li>\n
  • Vomiting and nausea<\/li>\n
  • Abdominal pain and discomfort<\/li>\n
  • Loss of appetite<\/li>\n
  • Restlessness or lethargy<\/li>\n<\/ul>\n

    Why Goat Milk Is Better<\/h2>\n
      \n
    • Less lactose<\/strong> than cow’s milk \u2014 easier to digest<\/li>\n
    • Smaller fat molecules<\/strong> \u2014 absorbed more easily<\/li>\n
    • Natural probiotics<\/strong> \u2014 support gut health and beneficial bacteria<\/li>\n
    • Rich in vitamins<\/strong> \u2014 A, D, B-complex, calcium, and magnesium<\/li>\n
    • Anti-inflammatory properties<\/strong> \u2014 may help dogs with skin issues<\/li>\n<\/ul>\n

      What About Puppies?<\/h2>\n

      Puppies should drink their mother’s milk<\/strong> or a veterinary-formulated puppy milk replacer<\/strong>. Cow’s milk is not<\/em> a suitable substitute \u2014 it has the wrong nutritional balance and can cause diarrhoea. Goat milk can be a supplement<\/strong> for orphaned puppies but shouldn’t replace proper puppy formula.<\/p>\n

      Frequently Asked Questions<\/h2>\n
