What Should I Feed My Dog? A Veterinarian’s Guide to Healthy Dog Nutrition

As veterinarians, one of the most common questions we hear from pet owners across San Francisco and the Bay Area is:

“What should I feed my dog?”

With so many options available — grain-free diets, raw food, fresh food subscriptions, boutique brands, homemade meals and traditional kibble — it’s understandable to feel overwhelmed. The truth is that the “best” diet depends on your dog’s age, breed, lifestyle, medical history, body condition and individual needs.

At MedranoVets, we believe nutrition is one of the most important foundations of lifelong health. A balanced diet supports:

  • Healthy weight management
  • Joint and mobility health
  • Skin and coat quality
  • Digestive health
  • Energy levels
  • Long-term disease prevention

Below, we break down what Bay Area dog owners should know about feeding their dogs — and how to tell if your pet is truly at a healthy weight.


🐶 What Makes a Good Dog Food?

The best dog food is one that is:

  • Complete and balanced
  • Appropriate for your dog’s life stage
  • Backed by veterinary nutrition research
  • Consistently formulated and quality tested

Look for foods that meet AAFCO nutritional standards, which indicate the food is formulated to provide complete nutrition for dogs.

Important Factors to Consider:

  • Age: Puppies, adults and senior dogs have different nutritional needs
  • Breed size: Large-breed puppies require carefully balanced calcium and calories
  • Activity level: Working or highly active dogs may need more calories
  • Medical conditions: Allergies, kidney disease, arthritis, obesity and GI issues may require prescription or specialized diets

🍖 Should I Feed Dry, Wet, Fresh or Raw Food?

There is no one-size-fits-all answer.

Dry Food (Kibble)

Kibble is convenient, cost-effective and nutritionally balanced when using a reputable brand.

Wet Food

Canned diets can help increase water intake and may be beneficial for picky eaters or pets with dental issues.

Fresh Food Diets

Fresh diets have become increasingly popular in the Bay Area. Some dogs do very well on them, but portion control and nutritional balance are essential.

Raw Diets

Raw feeding remains controversial within veterinary medicine due to concerns about:

  • Nutritional imbalance
  • Bacterial contamination
  • Risks to immunocompromised pets and people

If you are considering a homemade or raw diet, speak with your veterinarian or a board-certified veterinary nutritionist first.


⚖️ How Much Should I Feed My Dog?

One of the biggest contributors to health problems in dogs is overfeeding.

Even healthy foods can lead to:

  • Obesity
  • Arthritis progression
  • Diabetes
  • Heart disease
  • Reduced lifespan

Start With:

  • Your dog food bag’s feeding guidelines
  • Your veterinarian’s recommendations
  • Your dog’s body condition—not just weight

Helpful Dog Calorie Calculator

The Pet Nutrition Alliance Calorie Calculator is a useful starting point for estimating daily caloric needs:

Remember: calorie needs vary significantly depending on age, metabolism, activity level and medical conditions.


🩺 Is My Dog Overweight?

Many pet owners are surprised to learn their dog is overweight. In fact, veterinary studies estimate that over half of dogs in the United States are overweight or obese.

A healthy body condition matters far more than the number on the scale.

Signs Your Dog May Be Overweight:

  • Difficulty feeling the ribs
  • Loss of a visible waistline
  • Reduced stamina or exercise intolerance
  • Difficulty jumping or climbing stairs
  • Heavy panting during mild activity

📊 Body Condition Score (BCS): A Better Way to Assess Weight

Veterinarians often use a Body Condition Score (BCS) chart instead of relying only on weight.

In an ideal body condition:

✅ Ribs can be easily felt but not prominently visible
✅ Waist is visible from above
✅ Abdomen “tucks up” from the side

Helpful Body Condition Chart

The WSAVA Body Condition Score Chart is one of the most widely used veterinary tools:

Monitoring body condition regularly can help prevent obesity-related diseases before they start.


🦴 What Human Foods Are Safe for Dogs?

Some human foods are safe in moderation, including:

  • Plain cooked chicken
  • Carrots
  • Blueberries
  • Pumpkin
  • Green beans

However, many common foods are toxic to dogs.

🚫 Foods Dogs Should Never Eat

  • Grapes and raisins
  • Chocolate
  • Xylitol (found in sugar-free gum and peanut butter)
  • Onions and garlic
  • Alcohol
  • Macadamia nuts

If your dog ingests something toxic, contact your veterinarian or poison control immediately.

🐾 Nutrition Needs Change Throughout Life

Your dog’s nutritional requirements will change over time.

Puppies

Need higher calories and carefully balanced nutrients for growth.

Adult Dogs

Require maintenance nutrition tailored to activity level and lifestyle.

Senior Dogs

May benefit from:

  • Joint-support diets
  • Lower calorie intake
  • Increased digestibility
  • Prescription therapeutic diets

Routine veterinary exams help ensure your dog’s diet evolves appropriately with age and health status.
