There are various criteria classifying dogs in three main categories (small, medium, large) — however, many consider weight, size, and food labels as a norm for this distinction.  

Height is a determining category among breeders, pet owners, and food companies. In this article, if we say a giant breed, then it applies to dogs whose average height is over 26.

Another category which reflects extra-large canines is the weight, over 100 lbs.

Common Health Problems For Giant Dogs

Orthopedic Issues

Hip and elbow dysplasia are the two most common conditions affecting giant breeds. It starts in canines as they grow and results in an inability to move. Eventually, it can lead to joint degeneration, pain, and arthritis. With these two, genetics plays a significant role.

Since we are on the topic, we should mention arthritis as well. Even though it’s associated with senior dogs, arthritis can develop at any moment. It is linked with stiffness in the muscles, pain, limping, and restricted moving.

Heart Diseases

Heart condition such as aortic stenosis often happens in giant dogs. This disease modifies the heart’s valve or surrounding arteries which obstructs the blood flow, forcing the dog’s heart to pump more vigorously.

Symptoms may include:

  • A cough
  • Fainting
  • Difficulty in breathing
  • Exercise intolerance
  • Or no symptoms at all    

With severe cases, surgery is required, or beta-blocker drugs. Dogs with a mild case of the illness should avoid hot weather, intense exercise, and stay slim.

Eye Issues

Entropion is a painful medical condition which causes the eyelids to roll inwards. Even though it’s not unique to XXL breeds, it happens more often than with small ones. The symptoms include terry eyes, excessive blinking, and pain.

Another issue that may affect your canine is the ectropion where the eyelids roll outwards, exposing the inner lid’s tissue. Compared to entropion, it’s not as painful, and dogs can live with it comfortably.


Reduced production and release of hormones of T3 and T4 result in hypothyroidism. Since thyroid gland protects your pet’s body affecting the work of other organs, it’s essential to notice the initial signs:

  • Lethargy
  • Unexpected weight gain
  • Hair loss
  • Mental dullness
  • Skin infection  

With appropriate therapy and monitored iodine intake, you should be able to keep this condition under control.


Bloat is also known as gastric torsion, and this disease is frequently seen in extra-large dogs, due to their chest shape. Gas builds up in their gut and expands towards their chest. Overeating, or eating too quickly is considered to be one of the main reasons which cause bloat.

However, canines can end up in a life-threatening situation when stomach or bowels twist, obstructing the blood flow. In this case, your pet can die within 30 minutes.


An excessive amount of calories may cause obesity in giant breeds. Given their size, if you don’t pay attention to their diet, gigantic dogs can become massive.

However, pet owners are often careless, thinking the more, the merrier, which is true to some extent. But, too much weight can trigger the number of conditions, which can endanger your pet’s health. For instance, obesity can stress the joint, affect their heart, and increase blood sugar levels.

Feeding Guide For Giant-Sized Dogs

Nutritional Requirements

Due to their size, extra-large dogs are prone to many health conditions. For that reason, they require a slightly different diet adjusted towards their needs.

For instance, XXL dogs will benefit from foods rich in omega fatty acids, glucosamine, and chondroitin. It will protect their joint and promote bone growth.

Additionally, it would be wise to avoid caloric food, which can lead to obesity. When it comes to puppies, they also have unique food requirements. They should have a moderate and steady growth rate, by providing them top rated puppy food for a giant breed.

If you aren’t sure how to proceed further make sure to discuss this issue with your pet. Many commercial recipes have an excellent balance of protein, fats, and minerals, and can be an excellent choice for your pet.

However, in some cases, additional supplementation might be required.

How To Choose A Dog Food

  • Good Protein Source

Up until recently, it was thought that proteins were responsible for bone abnormalities and disorders in giant breeds. However, it’s not protein, but excess weight and calcium levels which contribute to this condition.

Based on AAFCO recommendations, adult canine requires 18% of the protein in his diet, while growing dog needs at least 22%. Unfortunately, the majority of dog food exceed this percentage. However, there doesn’t seem to any reason to restrict your pet’s diet.

The protein source is up to you and your pooch – whatever he likes.

  • Fat

While giant breeds can eat plenty of proteins, you need to be mindful about their fats intake. Parenting a gigantic dog requires a lot of responsibilities. For that reason, weight management and joint health should remain your priority.

Since they have a slow metabolism, giant breeds don’t need many calories per day. In fact, the best formulas are the ones that help your pet stay slim. Therefore, such a diet has a moderate amount of fat, up to 8%.

  • Fewer Calories

As we explained earlier, the more calories your pet consumes, the bigger he will get. While some pet owners think this it’s a good thing to have their dog big and robust, for giant breeds it’s a disadvantage.

An optimal amount of calories would be around 1,600 per day. Try to maintain this amount to avoid further health issues.

  • Glucosamine and Chondroitin

Supplements, such as chondroitin and glucosamine have numerous health benefits on extra-large dogs. You will find many dog food companies promoting them on the labels.

Supposedly, they should stimulate proper development of bones and healthy joints. However, the science is still not convinced about their effects. One thing is sure, glucosamine and chondroitin will not harm your pooch.

  • Optimal Amount Of Phosphorus & Vitamin D

Phosphorus and calcium are often linked together and ration 2:1 is ideal for appropriate hormonal balance. Phosphorus deficiency, although rare, happens when an excess of calcium is implemented.

Vitamin D plays a crucial role in phosphorus and calcium metabolism, and canines obtain it through a diet.

Food To Avoid

  • Dairy Products

While some dogs aren’t sensitive to dairy products, others experience diarrhea, vomiting, and nausea. Therefore, there are varied options for giving dairy products and milk to canines.

However, let’s focus on lactose, which is a primary ingredient in dairy products. Unfortunately, dogs can’t digest lactose. For that reason, there is no point in feeding your pet with milk, considering it has no nutritious value.   

  • Calcium

It’s a fact that giant breeds and puppies need calcium in their diet. However, many people think since they are big they require more calcium, than average canines, which false.

Too much calcium leads to many health disorders, such as OCD, or other developmental diseases. Experts recommend 1.5% of calcium in dog food.

  • Supplements

We would advise you not to add any supplements to your giant dog nutrition, no cottage cheese, yogurt, multivitamins, or other things. His diet needs to be balanced and complete.

However, if you resort to supplementing, then food will lose its purpose. Extra-large canines can be particularly sensitive to certain levels of minerals and vitamins. When you add supplements in their nutrition, you risk disrupting that balance, which can lead to many diseases.

Feeding Tips

When parent giant breed dogs you should be aware of a couple of feeding habits that may improve, or in some cases endanger their health:

  • Pups demand premium nutrition, holistic, all-natural, or organic
  • Make sure food is specially formulated for large or giant canines
  • You can use “all life stages food” as long it has all necessary nutrients
  • Due to a slow metabolism cut down calories
  • Limit calcium intake
  • Focus on high-quality proteins, such as chicken or turkey
  • Pay attention to fat content; it can lead to obesity; this doesn’t include omega fatty acids
  • Select recipes appropriate for their health issues

How Much And How Often To Feed

Feeding schedule has a significant impact on your pet’s development! So make sure to have a puppy food comparison before you choose one brand.

Tips In Proper Care For Extra Large Breeds

Monitor Weight & Activity

We don’t have to remind you how fast giant breeds grow. Therefore, if you feed them too much, they’ll grow broader and taller. Not only this will cause inconvenience, but it will be bad for their health.  

However, portioning their diet, and paying attention to ingredients they consume, may help you solve this issue. Big dogs are bursting with energy, that’s why keeping them busy during the week will manage their weight and improve their mood.

Practice Controlled Eating

Controlled eating is one form of training, which many pet parents don’t carry into effect. A lot of them believe into free feeding, which means the dog’s bowl is never empty.

Even when your dog whines, asking for more food, you should stick to a strict timetable.

Feed Low-Calorie Treats

Since giant breeds are pretty strong due to their size, proving an occasional treat during a training session won’t have a significant impact on his health. However, don’t go crazy with treats every day.

Go for low-calorie treats. They have balanced levels or proteins, fats, and carbohydrates. Their role is to manage weight and still serve as a motivation.
