Here's why:
* Lactose intolerance: Most adult dogs are lactose intolerant. They lack the enzyme lactase needed to break down lactose, the sugar in milk. This can lead to digestive problems like diarrhea, gas, and bloating.
* Nutritional imbalance: Milk is not a complete and balanced diet for dogs. It lacks the essential nutrients they need for healthy growth and development.
* Potential for allergies: Some dogs are allergic to milk proteins, which can cause itchy skin, ear infections, and gastrointestinal issues.
Instead of milk, offer your dog:
* Fresh water: This is the most important thing to keep your dog hydrated.
* Dog-specific treats: Many healthy and delicious treats are formulated specifically for dogs.
* Dog food: This provides the complete nutrition your dog needs.
If you're unsure about your dog's diet, always consult with a veterinarian.
