Do Giant Dogs Need Special Food?

Being a dog mom or dad is a huge responsibility, especially for giant breeds.

They need extra space in the home (and crate), XXL products, and usually cost more to insure and groom. And one thing’s for sure; they rack up a substantial monthly food bill. Although there is no set size for what constitutes a giant breed, it is commonly accepted that they weigh over 100 pounds at maturity.

If you are looking for the best food for giant breed puppies, we have a guide dedicated just to them. Although all dogs are different, most larger dog breeds reach maturity between 12 and 18 months. So this is the time to transition them between puppy and adult food slowly.

Giant Dog Breed Nutritional Needs

It’s important to realize that every dogs’ dietary needs are different.

It would be best if you based your nutritional choice on your dog’s specific dietary needs. Some may have specific health conditions requiring certain nutrients, and others require grain-free or grain-inclusive diets. Plus, believe it or not, some giant doggos are just downright fussy about flavors. Thankfully, you probably know what they already need or like by adulthood, making your choice more straightforward.

There isn’t a vast choice for giant-specific dog breed food. You should also be aware that feeding your big breed a food designed for large breed dogs is acceptable as long as it meets the nutritional levels established by the AAFCO Dog Food Nutrient Profiles. Adult dogs need a minimum of 18% crude protein and 5.5% fat to maintain a healthy lifestyle.

Bigger dogs carry a lot of weight which affects their joints, cardiac systems, and more, and they are also prone to excess weight gain. Large and giant dog breed food takes all of their nutritional needs into account. So it is essential to feed them these foods over poor-quality or generic ones. If you pick an option that isn’t specifically for large or giant dog breeds or tailored to their lifestyle, you are unlikely to meet their nutritional requirements.

Ingredients to Seek Out

Whatever specific dietary needs your dog has, all dogs need a well-balanced diet. To achieve this, you need to pick a high-quality food option rather than poor quality or store-branded food. High-quality companies use better-quality ingredients that provide the nutrients your dog needs to stay healthy.

Unfortunately, many food labels are misleading, so you cannot rely on labels to tell you the truth about a product’s nutritional value. Whether you choose kibble, wet food, or a tailored food subscription service, you must read the ingredient label and understand what to look for. Here are the main components of a healthy doggy diet and the ingredients that provide them.

Whole Meats

Raw meats on a table
Protein is the most important nutritional component of a dog’s diet.

The first ingredient in any ingredients list should always be meat, preferably whole meat such as chicken, beef, or deboned salmon. Protein is the most important nutritional component of a dog’s diet. This is because it provides energy and the essential building blocks for a healthy body, as well as fats, oils, vitamins, minerals, and yummy taste.

Meat meals are a great source of concentrated protein and are listed as chicken meal or beef meal, for example. It has up to four times the amount of protein than whole meat ingredients. The meat should be named and not listed as meat derivatives or poultry meal, for example. Unnamed ingredients pose a risk for those with intolerances. High-quality products are usually transparent on what meats they use.

Healthy Carbohydrates

Various Types of Grains
There are many vitamins, fibers, and other nutrients in rice that can be beneficial for dogs.

Healthy carbs are necessary for a dog’s diet, providing additional energy and nutrients that meat alone cannot. Healthy carbohydrates include veggies, such as sweet potatoes, lentils, and peas. Alternatively, grains are also used, including brown rice, oatmeal, and barley. All are suitable and provide the nutrients your dog needs, but you may want to consider the debate of grain vs. non-grain doggy diets if you haven’t already done so.

Omega Fatty Acids

The omega-3 oils found in fish provide vital fats to maintain a healthy coat, digestive system, and more.

Fats are often viewed as the enemy in both human and animal diets. However, they provide a wealth of nutritional benefits. High-quality products use healthy omega fatty acids, such as meat meals, fish, fish oils, eggs, plant oils, and flaxseeds. Omega fatty acids support the health of skin, coat, bones, organs, eyes, digestion, vitamin absorption, overall Wellness, and more. So, it’s important not to skip them.

As much as your giant Fido might persuade you, cheeseburgers and fries do not count as healthy fats. Big dogs are prone to weight gain. Additional weight gain might lead to further health problems, painful joints, a strained cardiac system, and a shortened lifespan. So please only feed them doggy food and no table scraps. Unless your vet says otherwise, a high-quality food product supplies all the healthy fats your dog needs.

Fruits and Vegetables

Vegetables and fruit are healthy alternatives for your pup.

Fruit and vegetables are other essential components of doggy diets. They provide vitamins, minerals, and antioxidants to keep their immune systems healthy and robust, enabling them to fight illness and disease. Plus, it keeps them feeling healthier thanks to a better oxidative state. Nutrient-rich fruits and veggies to look out for include blueberries, cranberries, kelp, carrots, and broccoli.

Fruits and veggies also provide fiber which is vital for digestive support and better stool health. Fiber is essential for greedy giants forever on the hunt for food, as it keeps them feeling fuller for longer. Great sources of fiber include sweet potatoes, pumpkin, and beet pulp.

Glucosamine

Glucosamine is essential for giant dogs because it supports joint health. Most high-quality dog foods increase the glucosamine content for giant breeds because they need it more than smaller dogs. This is mainly because their joints are under increased pressure from the extra weight. Look for ingredients such as meat meals, fish oil, eggs, green-lipped mussels, or additional glucosamine supplements.

Natural Preservatives

High-quality products are typically focused on natural food only, which is always best for our best friends. Preservatives are often required to keep food fresh, nutrient-rich, and edible. Ingredients such as ascorbic acid (vitamin C) and mixed tocopherols (vitamin E) are examples of natural preservatives. As well as botanical oils such as peppermint and rosemary extract. Artificial preservatives are more likely to irritate your dog’s digestive system.

So, it’s imperative to maintain a healthy weight.

Here we have two healthy weight options for giant dog breeds. If you notice your pup is gaining extra pounds, switching to a weight management kibble is essential and getting them moving more.
