The Rottweiler is a feisty and large lump of a breed, but one that is secretly a big softie at heart. At maturity, he will find himself anywhere between 80 and 135 pounds in weight, so it is safe to say that he is a large, and sometimes, giant dog breed. For this reason, he has unique nutritional needs which will determine the food choices you make for him.
Whilst he makes a loving family pet, he is a robust working breed that was traditionally used to herd and protect cattle, and he is now often worked in the personal protection arena, and he needs a lot of energy and protein to keep him sustained. Large breed foods with higher levels of protein are the key to keeping this big boy happy and healthy, and with the first 10 ingredients known to make up 80% of the food, it is super important to look at these ingredients.
After reading this Rottweiler nutrition guide, you’ll understand all you need to know about the Rottweiler and his unique breed needs, what nutrients he needs at each of his life stages, and ultimately which brands are the crème of the crop. So you don’t have to spend hours and hours trawling through hundreds of products, so we’ve made it nice and simple!

Rottweiler Puppy Nutrient Needs
The Rottweiler puppy needs a high-quality dog food that is specifically designed for large breed puppies, because not only do they have a higher number of calories that will help him to achieve full Rottweiler growth, but the calcium, phosphorus vitamin D, and fat levels will provide his growing bones with the strength that they need to be healthy. They will also control how quickly he grows, and this is important for large breeds such as the Rottweiler because if he grows too quickly, he is more likely to develop osteopathic diseases such as Hip Dysplasia, so standard ‘all-breed’ puppy food should be avoided at all costs.
The Rottweiler puppy needs a lot of protein, because not only does protein provide him with the energy and puppy power he needs to grow, but it also ensures that it keeps his muscles lean and strong. The MSD Veterinary Manual recommends that puppy kibbles should provide a minimum protein content of 22%, but larger dogs such as the Rottweiler should look for a minimum protein level of at least 26%. It also recommends that a minimum fat content of 8% is needed too.
Healthy carbohydrates are important because they will provide him with energy whilst keeping him feeling full, which will hopefully lower his snack begging and the chance of him becoming obese. Because Rottweilers are known to suffer from a variety of cardiac concerns, he should never be allowed to become overweight or eat fatty human foods. For this reason, plenty of omega fatty acids should be looked for, such as Salmon oils and flaxseed, as well as the ingredient taurine, which all help to look after his cardiac health, as well as overall coat and bone health.
Other vitamins and minerals will also help to support his developing immune system and keep him fighting fit against diseases, and docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and arachidonic acid (ARA) are amino acids that are naturally found in mothers’ milk, and they all support healthy brain development and eye function.
Adult Rottweiler Nutrient Needs
From the age of 18 months, the Rottweiler nears maturity and as such he should be switched to adult food. Again, it is important that the Rottweiler is fed a high-quality nutrition that caters to the unique nutritional needs of a large breed. Sometimes, with larger Rottweilers, many owners find that it is more suitable to feed them a giant dog breed, and this is normally saved for those pooches who exceed 100 pounds and more in weight. With that weight comes bone and joint pressure, so optimum calcium and phosphorus levels are key.
Protein is still an important factor to consider here, but typically he needs less than a puppy Rottie. Whilst the MSD Veterinary Manual recommends that adult dogs need a protein content of at least 18%, a larger, giant or more energetic breed such as the Rottie should be fed a higher protein content of at least 23%.
Ingredients such as fish oil and flaxseed will nourish his thick and dense coat, as well as keep his brain functioning healthily. Again, with the threat of cardiac issues, the ingredient taurine is favorable, and be sure not to feed him too many treats, no matter how much of a good boy he is.
Senior Rottweiler Nutrient Needs
A Rottweiler becomes a senior pooch around the age of 6 or 7, and at this time you should really look to change him to a food designed just for large breed seniors, or those that tick certain ‘large breed’ boxes, which we will talk you through.
As dogs age, they become less active, so it is important to put fewer calories into their bowl to ensure that he doesn’t become overweight. It is also important to ensure that the diet contains less fat as his aging digestive system will struggle to break it down efficiently.
Higher levels of glucosamine and chondroitin are key because of his weakening joints. Good sources of these can be found in meat and fish meals, as well as extra supplements. Again, the ingredient taurine is beneficial, as is L-carnitine as it helps to stimulate his metabolism, and it is also important to look for plenty of vitamins and minerals to help to boost his aging immune system so he can continue to fight illnesses.
Best Food For Rottweiler Puppies
Rottweilers between the ages of 8 weeks and 12 to 15 months, will need dry kibbles that can meet an aggressive puppy’s growth needs during that timeframe.

Best Food For Adult Rottweilers
Once your Rottie hits between 12 and 15 months, you’ll want to start the transition to an adult food. You’ll want to do this slowly, as doing it too quickly can make your Rottweiler get an upset stomach. Typically you’ll want to blend the puppy food with the adult food first, and then gradually migrate over completely to the adult food.
Because Rotties are a large breed, you’ll want to make sure you monitor their food intake so that they don’t overeat. Rottweilers are not typically picky eaters, but every dog is different. Their activity levels as adults will slow as they age, so it’s always best to break up feeding into 3-4 different sessions through the day if possible. Let’s look at our five favorite Rottie foods for adult pups.

We love that this Bison flavored recipe is made with zero Chicken or poultry ingredients, which makes a great option for those Rottie’s who are particularly fussy or have intolerances to these common ingredients.
Best Food For Senior Rottweilers
Once our pup hits around 8 years of age, you’ll want to start considering your pup eat a food that has a food formula specific for seniors. Rottweilers can also have joint and hip issues, so you may want to consider food with glucosamine as an option. It’s also possible your Rottie might have issues being “regular” so a higher fiber food might also be something advised by your vet.
Because your Rottweiler’s metabolism slows, you’ll want to make sure your pup has a lower calorie count or is just fed less food during feeding frequencies. Overeating typically isn’t a problem with Rotties, but you’ll know by adulthood if you need to deal with this issue later on in life as well. Below are our favorite foods for Senior Rotties. Let’s dive in!

Food For Overweight Rottweilers
At some point during their lifetime, many Rottweilers will find themselves on the porky side of the weight scales, and if this does happen, you need to take action to get them back to a healthy weight. The best thing you can do, along with daily exercise, is to take some calories out of his bowl and switch him to a weight management food. Extra unnecessary weight is associated with a wide variety of health problems, particularly for larger breeds, so be sure to take it seriously. Here are our top picks for the overweight Rottweiler.
Purina Pro Plan Weight Control
Purina Pro Weight Management
- Made specifically for heavier large breeds.

The protein content here is 26%, the fat content is 9% and the calorie count is 374 per cup. Whilst this recipe is slightly higher in fat and calories, Purina has made this with larger breeds in mind. This is a grain-inclusive recipe, but protein is still the first ingredient.
