Every dog owner wants the same thing — a happy, healthy dog who bounds through life with energy, a shiny coat and a wagging tail that never stops. And while walks, playtime and plenty of cuddles all play their part, nothing has a bigger impact on your dog's overall health than what goes in their bowl every single day.

But dog nutrition can feel overwhelming. With so many food options, conflicting advice and a growing list of what dogs can and can't eat, it's hard to know where to start. That's why we've put together this complete guide — everything you need to know about feeding your dog well, avoiding common mistakes and setting them up for a long and healthy life. 🐾


What Does a Balanced Dog Diet Actually Look Like?

A healthy, balanced diet for a dog should include the following key nutrients:

Protein is the most important building block of your dog's diet. It supports muscle development, energy levels and a healthy immune system. Good sources include chicken, turkey, beef, lamb, fish and eggs. Always make sure protein is listed as the first ingredient in any commercial dog food you buy.

Healthy fats are essential for a shiny coat, healthy skin and brain function. Look for foods containing omega-3 and omega-6 fatty acids — found naturally in salmon, sardines and flaxseed.

Carbohydrates provide your dog with sustained energy throughout the day. Sweet potato, brown rice and oats are all excellent sources that are gentle on digestion.

Vitamins and minerals support everything from bone health to immune function. A well-balanced commercial dog food should cover most of your dog's vitamin and mineral needs, but fresh vegetables can be a brilliant supplement.

Water is often overlooked but is absolutely essential. Always make sure your dog has access to fresh, clean water throughout the day — especially after exercise or on warmer days.


The Best Foods to Feed Your Dog

The good news is that many everyday foods are not only safe for dogs but genuinely beneficial to their health. Here are some of the best:

Lean proteins such as cooked chicken, turkey, beef and lamb are brilliant for dogs and form the foundation of a healthy diet. Always serve them plain and cooked — never seasoned or marinated.

Fish such as salmon and sardines are packed with omega-3 fatty acids, which support a shiny coat, healthy joints and brain health. Cooked and boneless is always best.

Eggs are a fantastic source of protein and healthy fats. Scrambled or boiled with no added butter or seasoning make a great occasional treat.

Sweet potato is one of the best vegetables you can give your dog — rich in fibre, vitamins and antioxidants, it's gentle on digestion and most dogs absolutely love it.

Carrots are low in calories, high in fibre and great for dental health. Most dogs love crunching on a raw carrot and they make a brilliant guilt-free treat.

Blueberries are packed with antioxidants and vitamins and make a wonderful occasional treat. Small enough to serve as a reward during training too!

Pumpkin is excellent for digestive health and is particularly helpful for dogs with sensitive stomachs. Plain cooked or tinned pumpkin (not pie filling) works brilliantly.

Oats are a gentle, easily digestible carbohydrate that provide sustained energy. Served plain and cooked with no added sugar or flavourings.


Foods That Are Toxic to Dogs — Keep These Out of Reach

This is arguably the most important section of this guide. Many everyday human foods are not just unhealthy for dogs — they are genuinely toxic and can cause serious harm or even be fatal. Every dog owner should know this list by heart.

Chocolate is one of the most well-known dangers to dogs. It contains theobromine, which dogs cannot metabolise. Even small amounts can cause vomiting, seizures and in severe cases, death. Dark chocolate and baking chocolate are the most dangerous.

Grapes and raisins can cause sudden kidney failure in dogs — even in very small quantities. The exact toxic compound is still unknown, which makes them particularly dangerous as there is no safe amount.

Onions and garlic — whether raw, cooked or powdered — damage red blood cells in dogs and can cause anaemia. This includes leeks and chives too, so always check the ingredients of any human food before sharing.

Xylitol is an artificial sweetener found in sugar-free chewing gum, sweets, peanut butter and some baked goods. It causes a rapid drop in blood sugar and can lead to liver failure. Always check labels carefully.

Macadamia nuts can cause weakness, vomiting, tremors and fever in dogs. Even a small amount can cause significant distress.

Avocado contains a compound called persin which can cause vomiting and diarrhoea in dogs. The stone also poses a serious choking hazard.

Alcohol should never be given to dogs under any circumstances. Even small amounts can cause serious liver and brain damage.

Cooked bones can splinter and cause internal injuries. Always opt for raw bones specifically designed for dogs, and always supervise chewing.

Caffeine found in coffee, tea and energy drinks is toxic to dogs and can cause rapid heart rate, seizures and tremors.

Corn on the cob — while corn itself is not toxic, the cob poses a serious choking and intestinal blockage risk and should always be kept away from dogs.


How Much Should You Feed Your Dog?

Every dog is different, and the right amount of food depends on your dog's age, size, breed and activity level. As a general guide:

Puppies need more calories relative to their size than adult dogs and should be fed three to four times a day to support their rapid growth and development.

Adult dogs generally do well on two meals a day — once in the morning and once in the evening — with portion sizes based on their weight and the guidelines on their food packaging.

Senior dogs may need fewer calories as their activity levels drop, but higher levels of joint-supporting nutrients such as glucosamine and omega-3s.

Always follow the feeding guidelines on your chosen dog food and adjust based on your dog's weight, energy levels and body condition. If you're ever unsure, your vet is always the best person to ask.


The Right Bowl Makes a Difference Too

It's not just what your dog eats — it's how they eat it. Feeding your dog at the right height can make a significant difference to their comfort and digestion, particularly for larger breeds and senior dogs.

Our Elevated Adjustable Double Dog Feeding Station 👈 is a brilliant solution — with three adjustable height settings (low 7cm, mid 19.5cm and high 30cm), it grows with your dog and reduces the strain on their neck and joints during mealtimes. Available in grey and black.

For something a little more decorative, our Elevated Double Stainless Steel & Ceramic Pet Bowls 👈 are available in six beautiful colours with a choice of stainless steel, ceramic or plain white plastic bowls — stylish enough to sit proudly in any kitchen. 💛

And don't forget — fresh water should always be available alongside every meal. A clean, well-placed water bowl is just as important as the food bowl itself. 🐾


Final Thoughts

Feeding your dog well is one of the greatest acts of love you can give them. A balanced diet packed with quality protein, healthy fats, fresh vegetables and plenty of water will keep them energetic, healthy and by your side for years to come.

And remember — when in doubt, always check with your vet. Every dog is unique, and professional advice is always the best place to start when making changes to your dog's diet.
