Questions to Ask the User First
- What type of pet? (Dog / Cat)
- What breed and age?
- What is your pet's current weight? (And is it ideal, overweight, or underweight?)
- What are you currently feeding? (Brand, type, amount)
- Does your pet have any health conditions? (Allergies, kidney disease, diabetes, pancreatitis, etc.)
- What is your concern? (General nutrition / Weight management / Diet change / Reading labels / Toxic food question)
- What is your budget for pet food? (Budget / Mid-range / Premium / No limit)
- Does your pet have any food sensitivities or preferences?
- Is your pet spayed/neutered? (Affects caloric needs)
Reading Pet Food Labels
Understanding AAFCO Standards
AAFCO (Association of American Feed Control Officials):
- Sets nutritional standards for pet food in the US
- Does NOT test or certify food (common misconception)
- Defines nutrient profiles for "complete and balanced" nutrition
- Two life stages: "Growth and Reproduction" and "Adult Maintenance"
- "All Life Stages" meets the higher growth requirements
WHAT TO LOOK FOR ON LABELS:
1. AAFCO NUTRITIONAL ADEQUACY STATEMENT:
Best: "[Product] is formulated to meet the nutritional levels
for [Life Stage]."
Also Good: "Animal feeding tests using AAFCO procedures substantiate
for [Life Stage]."
2. GUARANTEED ANALYSIS (Minimum/Maximum):
- Crude Protein (min %): Higher is generally better
- Crude Fat (min %): Energy source
- Crude Fiber (max %): Digestive health
- Moisture (max %): Important for comparing wet vs dry
3. INGREDIENT LIST:
- Listed in order of weight (before processing)
- First 5 ingredients matter most
- Look for named protein sources (chicken, beef, salmon)
- Avoid vague terms ("meat meal," "animal by-products")
Decoding Ingredient Labels
PROTEIN SOURCES (Best to Acceptable):
Excellent: "Deboned chicken," "Fresh salmon," "Turkey"
Good: "Chicken meal" (concentrated protein, moisture removed)
Acceptable: "Poultry meal" (less specific but still protein)
UNDERSTANDING "MEAL":
- "Chicken meal" = chicken with water removed (concentrated protein)
- Not inherently bad -- it's actually higher in protein by weight than "chicken"
- "Chicken" listed first may actually contain less protein than "chicken meal"
second, because fresh chicken is 70% water
CARBOHYDRATE SOURCES:
Whole grains: Brown rice, oatmeal, barley (good fiber + nutrients)
Grain-free alternatives: Sweet potato, peas, lentils, chickpeas
NOTE ON GRAIN-FREE DIETS:
- FDA investigation into possible link between grain-free diets and
dilated cardiomyopathy (DCM) in dogs
- No definitive conclusion yet, but discuss with your vet
- Grain-free is NOT inherently better or healthier
- Only feed grain-free if medically necessary (grain allergy)
FILLERS AND ADDITIVES:
Beneficial: Chelated minerals, probiotics, omega-3 sources (fish oil)
Acceptable: Natural preservatives (mixed tocopherols, rosemary extract)
Avoid: BHA, BHT, ethoxyquin (artificial preservatives)
Avoid: Propylene glycol, excessive salt or sugar
Comparing Dry vs Wet vs Raw
| Factor | Dry Kibble | Wet/Canned | Raw |
|---|
| Moisture | 6-10% | 75-85% | 60-70% |
| Calorie Density | High | Low | Medium |
| Dental Health | Mild benefit | No benefit | Bone chewing benefit |
| Shelf Life | Long | Long (unopened) | Short |
| Convenience | High | Medium | Low |
| Cost per Serving | Low | Medium-High | High |
| Palatability | Moderate | High | High |
| Hydration Benefit | Low | High | Moderate |
Dry Matter Basis Comparison
To compare protein across foods with different moisture levels:
FORMULA:
Dry Matter Protein % = (Protein % on label) / (100 - Moisture %) x 100
Wet Food: 10% protein, 78% moisture
DM Protein = 10 / (100-78) x 100 = 45.5%
Feeding Schedules by Age and Size
Dog Feeding Schedule
PUPPIES (8 weeks - 4 months):
- Feed 3-4 times per day
- Puppy-specific food (higher protein, fat, calcium)
- Amount: Follow package guidelines, adjust based on body condition
- Small breeds: May need 4 meals (prone to hypoglycemia)
PUPPIES (4 months - 12 months):
- Feed 2-3 times per day
- Continue puppy food
- Large breeds: Transition to large-breed puppy food (controlled calcium)
- Small breeds: May transition to adult food at 9-12 months
ADULT DOGS (1-7 years):
- Feed 2 times per day (morning and evening)
- Adult maintenance formula
- Amount based on weight, activity level, metabolism
SENIOR DOGS (7+ years, varies by breed):
- Feed 2 times per day
- Senior formula (lower calories, joint support)
- May need smaller, more frequent meals if digestion slows
- Monitor weight closely
DAILY CALORIE REQUIREMENTS (APPROXIMATE):
Dog Weight | Inactive | Moderate | Active
-----------|----------|----------|-------
10 lbs | 200 cal | 275 cal | 400 cal
20 lbs | 325 cal | 450 cal | 650 cal
30 lbs | 450 cal | 600 cal | 875 cal
50 lbs | 650 cal | 900 cal | 1,300 cal
70 lbs | 850 cal | 1,150 cal| 1,650 cal
90 lbs | 1,050 cal| 1,400 cal| 2,000 cal
Spayed/neutered pets may need 20-30% fewer calories.
Cat Feeding Schedule
KITTENS (8 weeks - 6 months):
- Feed 3-4 times per day
- Kitten-specific food (higher protein and calories)
- Can offer unlimited kibble + scheduled wet food meals
- Kittens rarely overeat (unlike puppies)
KITTENS (6-12 months):
- Feed 2-3 times per day
- Continue kitten food until 12 months
- Begin transition to adult food at 10-12 months
ADULT CATS (1-10 years):
- Feed 2-3 meals per day (preferred over free-feeding)
- Measured portions based on weight
- Wet food at least once daily (hydration benefits)
- Cats are obligate carnivores: protein is critical
SENIOR CATS (10+ years):
- Feed 2-3 smaller meals
- Senior formula or highly digestible food
- May need increased protein (muscle maintenance)
- Monitor weight changes closely
DAILY CALORIE REQUIREMENTS (APPROXIMATE):
Cat Weight | Indoor/Inactive | Moderate | Active
-----------|----------------|----------|-------
6 lbs | 150 cal | 180 cal | 220 cal
8 lbs | 180 cal | 220 cal | 270 cal
10 lbs | 210 cal | 260 cal | 320 cal
12 lbs | 240 cal | 300 cal | 360 cal
14 lbs | 270 cal | 330 cal | 400 cal
Obesity is the #1 nutritional problem in cats.

Raw Diet Considerations
Raw Diet Overview
TYPES OF RAW DIETS:
1. Commercially prepared raw (frozen or freeze-dried): Safest option
2. BARF (Biologically Appropriate Raw Food): Bones, organs, muscle, veggies
3. Prey model: Whole prey ratios without plant matter
4. Home-prepared raw: Custom recipes
POTENTIAL BENEFITS (Claimed):
- Shinier coat
- Smaller, firmer stools
- Improved energy
- Better dental health
- Reduced allergies
POTENTIAL RISKS (Documented):
- Bacterial contamination (Salmonella, E. coli, Listeria)
* Risk to pet AND humans in household
* Especially dangerous for immunocompromised people, children, elderly
- Nutritional imbalance if not properly formulated
- Bone fragment hazards (obstruction, perforation, broken teeth)
- More expensive and time-consuming
- No strong scientific evidence of superiority over quality commercial diets
IF PURSUING RAW:
- Consult a veterinary nutritionist (board-certified DACVN)
- Use commercially prepared raw with AAFCO statement
- If home-preparing: work with a nutritionist for balanced recipes
- Handle with food safety precautions (wash hands, surfaces, bowls)
- Not recommended for homes with immunocompromised individuals
- Not recommended for puppies/kittens (higher risk)
Weight Management
Body Condition Scoring (1-9 Scale)
1-3: UNDERWEIGHT
- Ribs, spine, hip bones easily visible
- Obvious loss of muscle mass
- No palpable body fat
- Action: Increase calories, vet check for underlying disease
4-5: IDEAL
- Ribs easily felt with slight fat covering
- Waist visible from above
- Abdominal tuck visible from side
- Action: Maintain current diet and exercise
6-7: OVERWEIGHT
- Ribs hard to feel under fat layer
- Waist barely visible from above
- Little abdominal tuck
- Action: Reduce calories 15-20%, increase exercise
8-9: OBESE
- Cannot feel ribs at all
- No waist visible, may have "barrel" shape
- Fat deposits on neck, limbs, base of tail
- Action: Vet consultation, structured weight loss plan
HEALTH RISKS OF OBESITY:
- Diabetes (especially cats)
- Arthritis and joint problems
- Heart disease
- Reduced lifespan (up to 2 years shorter)
- Respiratory issues
- Increased surgical/anesthetic risk
- Heat intolerance
Weight Loss Protocol
STEP 1: VET CONSULTATION
- Rule out thyroid issues (hypothyroidism in dogs, rare in cats)
- Get target weight and timeline
- Discuss any food restrictions
STEP 2: CALCULATE CALORIES
- Target calories = RER for IDEAL weight x activity factor
- RER (Resting Energy Requirement) = 70 x (ideal weight in kg)^0.75
- Weight loss factor: RER x 1.0 (strict) to x 1.2 (moderate)
- Aim for 1-2% body weight loss per week
STEP 3: FEEDING PLAN
- Measure food precisely (use a kitchen scale)
- Feed 2-3 meals per day (no free-feeding)
- Reduce treats to <10% of daily calories
- Use portion of daily kibble as training treats
- Add water or low-sodium broth to food for fullness
- Consider weight management formula (higher fiber, lower calorie)
STEP 4: EXERCISE
Dogs: Gradually increase walks by 5 minutes per week
Cats: Interactive play 15-20 min daily, puzzle feeders
STEP 5: MONITOR
- Weigh every 2 weeks
- Body condition score monthly
- Adjust calories if loss is too fast or too slow
- Celebrate milestones

Hydration
Water Requirements
DOGS:
- General rule: 1 oz of water per pound of body weight per day
- 50-lb dog: approximately 50 oz (about 6 cups) per day
- More needed: hot weather, exercise, nursing, illness
- Less needed: dogs eating wet food
CATS:
- General rule: 3.5-4.5 oz of water per 5 lbs of body weight per day
- 10-lb cat: approximately 7-9 oz per day
- Cats have low thirst drive (desert-adapted ancestors)
- Chronic dehydration is common in cats eating only dry food
ENCOURAGING WATER INTAKE:
Dogs:
- Fresh water available at all times
- Clean bowl daily
- Multiple water stations
- Add ice cubes (some dogs enjoy this)
- Water fountain (movement attracts drinking)
Cats:
- Cat water fountains (many cats prefer running water)
- Wide, shallow bowls (whisker fatigue with deep bowls)
- Separate water from food station
- Multiple water stations
- Add water to wet food
- Flavor water with tuna juice (small amount, low sodium)
- Feed wet food at least once daily
DEHYDRATION SIGNS:
- Skin tent test: Pinch skin on back of neck; should snap back immediately
- Dry gums (tacky or sticky)
- Sunken eyes
- Lethargy
- Reduced urination
- Panting (cats: serious sign)
Breed-Specific Nutritional Considerations
Large/Giant Breed Dogs
PUPPIES:
- Large-breed puppy food (controlled calcium and phosphorus)
- Prevents too-rapid growth (skeletal problems)
- Calcium: 0.8-1.5% on dry matter basis (not more)
- Do NOT supplement calcium
- Feed to moderate growth rate (not maximum)
- Transition to adult food at 12-18 months (giant breeds 18-24 months)
ADULTS:
- Joint support supplements (glucosamine, chondroitin, omega-3)
- Monitor caloric intake (obesity worsens joint issues)
- Consider elevated feeding bowls (bloat risk is debated)
- Avoid exercise immediately after eating (bloat prevention)
- Feed 2-3 smaller meals instead of one large meal
Small Breed Dogs
PUPPIES:
- Small-breed puppy formula (smaller kibble, calorie-dense)
- Feed 3-4 times per day (prone to hypoglycemia)
- Always have food available for very small puppies under 4 months
ADULTS:
- Higher calorie per pound needs (fast metabolism)
- Dental health is a major concern (small mouths, crowded teeth)
- Consider dental diet or dental chews
- Smaller, calorie-dense kibble
Brachycephalic Breeds (Flat-faced)
CONSIDERATIONS:
- Difficulty eating from deep bowls (use flat or puzzle feeders)
- Prone to overheating (don't exercise after meals)
- May swallow more air while eating (gas, bloating)
- Slow feeder bowls recommended
- Elevated feeding position may help
Cat Breeds
MAINE COON / LARGE BREEDS:
- Higher calorie needs during growth (slow maturing)
- Joint support for larger frame
- May benefit from larger kibble size
SIAMESE / ORIENTAL:
- Tend to be lean; may need slightly higher calories
- Can be picky eaters
PERSIAN / FLAT-FACED:
- Difficulty grasping food (almond-shaped kibble designs)
- Prone to eye-related eating difficulties
- May prefer wet food
BENGAL / ACTIVE BREEDS:
- Higher calorie needs for activity level
- May benefit from higher protein formulas
Treats and Portions
The 10% Rule
Treats should make up NO MORE than 10% of daily caloric intake.
Common Treat Calories:
- Small commercial treat: 5-15 cal
- Medium biscuit: 30-50 cal
- Milk-Bone (large): 115 cal
- Pig ear: 200+ cal
- Bully stick (6"): 80-100 cal
- Baby carrot: 4 cal
- Blueberry: 1 cal
- Piece of cheese (1" cube): 70 cal
- Hot dog slice: 15 cal
HEALTHY, LOW-CALORIE TREAT OPTIONS:
Dogs: Baby carrots, green beans, apple slices, blueberries, ice cubes
Cats: Freeze-dried single-ingredient treats, small pieces of cooked chicken
