Buyer’s Guide

Giant breeds are some of the most fascinating, eye-catching, and amazing dogs. They are also often some of the most misunderstood, at least in terms of what they need to keep them going.

Their huge bodies need to be in prime condition to keep up. Just the sheer size of them takes a toll on their bodies, so feeding them correctly is vital to make sure they have the best chance of a healthy life.

What Makes A Dog A Giant Breed?

This is a topic of much debate in the doggy world. There are no universal criteria separating the larges from the giants. Wikipedia tentatively suggests that giant breeds may be any one that grows to over 50kg (110lb), although that can include some bigger large breeds such as Labradors.

For the purpose of this article, we have defined some criteria that seem to be accepted and would put a pup on the giant side rather than large. Both of these criteria being met almost certainly defines your pup as a giant!

  • Average adult weight 110 pounds or above
  • Height (adult) 24 inches or over

If your pooch meets both of these criteria, you most likely have a giant breed pet! If they weigh 100 plus pounds but are shorter than specified, you may need to find out if your pup is overweight. Perhaps they are tall but don’t weight as much. In this case, they may be underweight and need some feeding up! Do your research before deciding though.

Why Giant Breeds Need Specific Nutrition

The Association of American Feed Control Officials (AAFCO) publish yearly nutritional guidelines for pet foods. All pet foods must meet AAFCO’s standards. In 2016, they brought in new guidelines for giant breed pets (AAFCO classifies adult pets of 70 pounds and over as giant breeds). The reason for these new guidelines is that giant breeds need more of certain vitamins and minerals than other smaller breeds.

Giant breed dog food is typically less calorie and nutrient-dense than others, and for good reason. The larger the breed, the slower their metabolism. Also, because of their lanky frames, any excess weight can put a strain on bones and joints. When looking for the best giant breed dog food for your pup, you should take note of the following:

  • Protein content – according to AAFCO, an adult dog requires 18% protein, while a growing puppy needs around 22%
  • Fat – giant breeds should stick to around 8% fat in their diet
  • Carbohydrates – A blend to keep your pup’s energy up.
  • Calories – bigger animals have slower metabolisms, and especially for giants who tend to have less energy. Too many calories add too much weight to their skinny frames. A good guideline is 20 calories per pound per day. Of course, use your discretion.
  • Calcium content – Too much calcium can cause your pup’s bones to become too brittle. While calcium is essential to have for bone growth, AAFCO recommends 2.0 to 4.5 g calcium per 1000 calories. Be sure to check this before buying food!
  • Phosphorous content – This should be considered as a ratio to calcium. Use this calculator to check that the levels are correct on your pup’s food.
  • Glucosamine – This assists in keeping your giant pet’s joints strong and supple.
  • Other – Vitamin D, omega-3 fatty acids, and healthy oils should be present in your dog’s diet.

If you still aren’t sure where your pup stands, here are some of the most common giant breeds in the US:

Frequently Asked Questions

How do I know if my pup is a giant or a large breed?

If your (adult) dog is taller than 26 inches and weighs more than 110 pounds, it is almost certainly a giant. If you are unsure whether your puppy is a large or a giant, you may have to consult your vet and see if they can give you an estimate on how much your pup might weigh at maturity.

Can I feed my giant breed any pet food, or does he need special food?

While you can feed your giant breed regular large breed food, sometimes this doesn’t quite do it for them. To keep your giant in optimum health, it’s recommended to give them food that is specifically formulated for them.

What are some health issues giant breed dogs can suffer from?

Giant breed dogs’ bodies tend to take more of a beating than small breeds, due to their sheer size. This can lead to problems such as orthopedic disease (bone disease), joint weakness and issues (such as hip and elbow dysplasia), and arthritis.

They can also suffer from heart problems such as cardiomyopathy (the heart becomes too weak to pump blood effectively through their large body), hypothyroidism (a hormone condition), and gastric torsion (more common in giant breeds with protruding, deep, narrow chests).
