Dog Nutrition and Hydration: A Complete Guide to Lifelong Health

Learn how to tailor your dog’s diet and hydration to age, breed, and activity level. Safe and unsafe foods, daily water needs, and practical tips for everyday health.

Why Nutrition and Hydration Matter

Nutrition and hydration are the foundations of your dog’s health. The right diet and proper fluid intake don’t just help maintain an ideal weight; they are essential for preventing disease and supporting physical and cognitive function over time.

A Tailored Diet: Age, Breed, and Activity Level

Puppies, Adults, and Seniors: How Many Meals a Day?

There is no one-size-fits-all diet for every dog. Puppies need several small meals a day, adult dogs usually do best on two meals, while senior dogs benefit from smaller portions and formulas designed to support healthy aging.

When a Specific Diet Is Needed

Special situations such as pregnancy, high activity levels, or chronic conditions often require targeted dietary adjustments. In these cases, consulting a veterinary nutritionist helps ensure complete and balanced nutrition.

Why a Veterinary Nutrition Check-Up Matters

Weighing your dog regularly and having your vet assess body condition are key steps to spotting weight changes early and preventing long-term health problems.

Safe and Unsafe Foods: What Your Dog Can (and Can’t) Eat

Dog-Friendly Human Foods

Some vegetables and “human” foods can safely enrich your dog’s diet, such as carrots, zucchini, broccoli, pumpkin, brown rice, and small amounts of plain yoghurt or fish oil.

Foods You Must Avoid

Others are strictly off-limits because they can be toxic or dangerous, including chocolate, grapes and raisins, onions, garlic, alcohol, coffee, avocado, salty cured meats, cooked bones, and large amounts of dairy.

How to Introduce New Foods Safely

Always introduce new foods gradually, in small portions, and monitor your dog for any signs of digestive upset or intolerance.

The Importance of Water: How Much Should Your Dog Drink?

Daily Water Needs

As a general guideline, a dog should drink roughly 50–70 ml of water per kilogram of body weight per day, with adjustments for climate, activity level, and type of food.

Hidden Risks of Poor Hydration

Chronic underhydration can increase the risk of kidney problems, heatstroke, fatigue, and reduced performance, especially in active or older dogs.

Simple Ways to Encourage Your Dog to Drink

Offer multiple water bowls around the home and garden, keep water fresh and bowls clean, consider a pet fountain, and add a little water to food to gently boost daily intake.

Monitoring Weight and Body Condition

Regular weight checks and body condition scoring, combined with veterinary visits, allow you to adjust portions in time and support your dog’s long-term health.
