Nutrition Guide for Dogs
Complete Guide to Feeding Your Canine Companion
Introduction
Proper nutrition is the foundation of your dog's health and longevity. This comprehensive guide will help you make informed decisions about what to feed your dog, how much, and when, ensuring they receive all the nutrients needed for a healthy, active life.
Understanding Your Dog's Nutritional Needs
Six Essential Nutrients
1. Proteins
**Purpose:** Build and repair muscles, organs, skin, and hair; produce antibodies, enzymes, and hormones.
**Sources:**
- Meat (chicken, beef, lamb, turkey, fish)
- Eggs
- Dairy products
- Plant proteins (less bioavailable)
**Requirements:**
- Puppies: 22-32% of diet
- Adult dogs: 18-25% of diet
- Senior dogs: 18-25% (higher quality protein)
- Active/working dogs: 25-30% of diet
2. Fats
**Purpose:** Energy source, absorption of vitamins A, D, E, and K; healthy skin and coat; brain development.
**Essential fatty acids:**
- Omega-3 (EPA, DHA): Fish oil, flaxseed
- Omega-6: Poultry fat, vegetable oils
**Requirements:**
- Puppies: 8-20% of diet
- Adult dogs: 5-15% of diet
- Optimal ratio: Omega-6 to Omega-3 should be 5:1 to 10:1
3. Carbohydrates
**Purpose:** Energy source, digestive health (fiber).
**Sources:**
- Whole grains (brown rice, oats, barley)
- Vegetables (sweet potatoes, peas, carrots)
- Fruits (in moderation)
**Note:** Dogs don't require carbohydrates but can digest them efficiently. Fiber aids digestion.
4. Vitamins
**Fat-soluble vitamins:**
- Vitamin A: Vision, immune function, skin health
- Vitamin D: Bone health, calcium absorption
- Vitamin E: Antioxidant, cell function
- Vitamin K: Blood clotting
**Water-soluble vitamins:**
- B-complex: Energy metabolism, nervous system
- Vitamin C: Dogs produce their own (supplementation usually unnecessary)
5. Minerals
**Macrominerals:**
- Calcium & Phosphorus: Bone and tooth health (proper ratio crucial)
- Magnesium: Enzyme function, bone health
- Sodium & Chloride: Fluid balance, nerve function
- Potassium: Muscle function, metabolism
**Trace minerals:**
- Iron, Zinc, Copper, Manganese, Selenium, Iodine
**⚠️ Warning:** Over-supplementation can be harmful. Commercial dog foods are typically balanced.
6. Water
**Most critical nutrient!**
**Requirements:**
- Generally: 1 ounce per pound of body weight daily
- More needed if:
- Hot weather
- High activity level
- Nursing mothers
- Eating dry food
**Signs of dehydration:**
- Dry gums
- Loss of skin elasticity
- Sunken eyes
- Lethargy
Life Stage Nutrition
Puppies (Birth to 12-24 months)
**Growth stages:**
- Small breeds: Mature at 9-12 months
- Medium breeds: Mature at 12 months
- Large breeds: Mature at 12-15 months
- Giant breeds: Mature at 18-24 months
**Nutritional needs:**
- Higher protein (22-32%)
- Higher fat (8-20%)
- Proper calcium-phosphorus ratio (1:1 to 1.5:1)
- Small, frequent meals
**Feeding schedule:**
- 8-12 weeks: 4 meals per day
- 3-6 months: 3 meals per day
- 6-12 months: 2 meals per day
**⚠️ Large/giant breed caution:**

- Use large breed puppy formula
- Avoid calcium supplements
Adult Dogs (1-7 years)
**Nutritional needs:**
- Protein: 18-25%

Senior Dogs (7+ years)
**Age considerations:**
- Small breeds: Senior at 10-11 years
- Medium breeds: Senior at 8-9 years
- Large breeds: Senior at 6-7 years
- Giant breeds: Senior at 5-6 years
**Nutritional needs:**
- High-quality protein (easier to digest)
- Moderate fat (5-10% for less active dogs)
- Lower calories (decreased activity)
- Higher fiber (digestive health)
- Joint support (glucosamine, chondroitin)
- Antioxidants (Vitamins E, C)
**Special considerations:**

- Easy-to-digest ingredients
How Much to Feed
Calculating Daily Calories
**Resting Energy Requirement (RER):**
RER = 70 × (body weight in kg)^0.75
**Maintenance Energy Requirement (MER):**
- Neutered adult: RER × 1.6
- Intact adult: RER × 1.8
- Inactive/obese prone: RER × 1.2-1.4
- Active adult: RER × 2.0
- Very active/working: RER × 3.0-5.0
- Puppy (0-4 months): RER × 3.0
- Puppy (4-12 months): RER × 2.0
- Senior (less active): RER × 1.2-1.4
- Pregnant dog (first 42 days): RER × 1.8
- Pregnant dog (last 21 days): RER × 3.0
- Nursing mother: RER × 4.0-8.0
Feeding Guidelines by Weight
**These are general guidelines - adjust based on individual needs:**
**Small Dogs (2-20 lbs):**
- 5 lbs: ⅓ - ½ cup per day
- 10 lbs: ¾ - 1 cup per day
- 20 lbs: 1¼ - 1¾ cups per day
**Medium Dogs (21-50 lbs):**
- 30 lbs: 1¾ - 2¼ cups per day
- 40 lbs: 2 - 2⅔ cups per day
- 50 lbs: 2⅓ - 3 cups per day
**Large Dogs (51-100 lbs):**
- 60 lbs: 2¾ - 3½ cups per day
- 70 lbs: 3 - 3¾ cups per day
- 80 lbs: 3¼ - 4¼ cups per day
- 100 lbs: 3¾ - 5 cups per day
**Giant Dogs (100+ lbs):**
- Consult with a veterinarian
- Generally 4-8+ cups per day, depending on size and activity
⚠️ These are approximations based on average dry kibble (350-400 kcal/cup). Always check the calorie content of your specific food.
Body Condition Scoring
9-Point Scale
**1-3: Underweight**

- Waist barely visible
- Abdominal tuck minimal
**8-9: Obese**
- Ribs cannot be felt
