How Much Crude Protein Should Be In Dog Food

What Is My Take

Eating Dog Food – Pedigree Lamb and Casserole Dog Food

Choosing a high-quality food from the hundreds of available brands and formulas can be challenging. The pet nutrition industry is very competitive, and most commercially available foods are very good balanced diets. Ask your veterinary health care team to help you select a diet that is backed by scientific principles and research and that meets your dog’s individual needs. If you have any questions about a particular food, your best source for help is your veterinary health care team.

The Dangers Of The Crude Protein Method

Baby formula was being contaminated with melamine a plastic thats rich in nitrogen. As you can guess, it was added to the formula to increase nitrogen content to get a good crude protein score. Of course, they got what they wanted, deceived unsuspecting law enforcement agents as well as customers and sold their products by the truckload.

Unfortunately, it was innocent babies that paid the price. 6 babies died from kidney damage, while about 54,000 others were hospitalized.

There have also been cases where urea was added to animal feed just to get a good crude protein score for the labels and sell more products.

Sadly, urea and melamine are toxic for the consumption of animals with a single compartment stomach. Thankfully, they are both on the banned food ingredient list for man and animals, but then again, it hasnt stopped the most notorious of manufacturers.

Nonetheless, this only goes to show, even more, why the crude protein method is not just an unreliable method but a potentially dangerous one as well.

To put things in perspective, including a missing amino acid will actually improve the quality of a particular food. However, this inclusion does not always reflect in an increase in the crude protein content.

On the other hand, when unbalanced food has a high crude protein, it could cause an interruption in protein synthesis, as well as stunt growth and health just like we saw in the scenario above.

Daily Nutritional Requirements Of An Elderly Dog

Obesity is an important concern in elderly dogs. Senior pets tend to slow down and become less active. Eating their usual diet may cause weight gain. You’ll want a low-calorie food that still has adult levels of protein and fat. It’s recommended that elderly dogs receive around 200 to 300 calories per day per ten pounds of body weight.

Another concern is constipation. Senior dogs don’t walk around as much, an activity that stimulates bowel activity. Look for dog foods that are high in fiber, those with four to five percent by weight are optimal.

Why Do Cats Need Protein

  • They are a source of various amino acids used as protein building blocks that make the various body organs and tissues including tendons, cartilages, skin, hair, muscles and so on.
  • They work as hormones, antibodies, enzymes, and help in proper pH balance.
  • Together with fats, these two their primary source of energy.

Too Much Protein In Dog Food Cause Diarrhea

What is Crude Protein in Cat Food?

Even if dogs need a lot of protein, too much intake of protein can cause diarrhea. That is why you need to make sure that your dog has a balanced diet. An unbalanced diet can also damage its kidney since the dog cannot store the protein for later use. The body will excrete the excess protein through urine and feces and will make the kidney and digestion system work harder.

Crude Protein In Complete Dog Food

When used in dog food, crude protein is often given as part of a blended mix. The non-grain ingredient is highly processed and inedible for humans.

A blended blend has many ingredients, including vegetable proteins, with the majority of the mix made up of raw ground meat. Sometimes, all the ingredients in the blend are raw ground meat, making it very rich in nutrients.

Monitor Your Dogs Nutrition And Health

Even after following all these steps, its still important to monitor how your dog thrives on any diet hes currently on. If your dog appears to be doing better, great. If he appears to be deteriorating, poor skin and fur health, poor muscle development, then thats indicator enough that that food isnt good for your dog.

Also, dont be shy to ask other dog parents with obviously healthy dogs what they fed their pups as well. You might actually get a recommendation that works.

In all, you must consult your vet before changing your pups diet willy-nilly. Experimenting with your dogs food, oftentimes, does more harm than good to your dog.

How important is fat for dogs?

Dietary fats are essential for your dog. Not only do they provide energy, but they also support cell growth, maintain healthy skin, fight inflammation, protect the organs, and keep the body warm. Fats also help with the absorption of nutrients and help to produce some important hormones. Lastly, fat is a carrier for fat-soluble vitamins. These vitamins are vitamin A, vitamin D, vitamin E, and vitamin K. Consuming enough fat is thus essential for an adequate intake of these vitamins. So, overall, fat is very important for dogs.Your dog especially needs essential fatty acids in their diet. These fatty acids cannot be synthesized by a dogs own body, so they must be provided by the diet. Such Omega-3 fatty acids include alpha-linolenic acid, eicosapentaenoic acid , and docosahexaenoic acid . Your dog also needs Omega-6 fatty acids like linoleic acid to stay healthy.

Crude Protein & Amino Acids In Dog Food

Is Your Cat Food Safe? How To Read A Pet Food Label

Crude protein is an excellent source of amino acids and is much more digestible than protein found in fruits, vegetables or grains.

Its easy for the dogs to convert the crude protein into its individual amino acids.

Human and pet nutritionists often refer to it as the gold standard of protein.

Sometimes processed, non-meat proteins are also included as a protein source in dog foods. They are often very high in calories, carbohydrates and fats and not terribly digestible by dogs.

How Much Is Too Much Protein In Dogs

Although protein is necessary for dog nutrition, like everything else, too much is never good. It means that too much protein in your dogs diet might not be good too.

Dogs will only be able to digest and absorb the protein that their body needs for maintaining their muscle mass and other tissues. Any excess protein in their diet can either be disposed of through urine or stored in their body as fat.

If your pets are putting on weight, it might be ideal for checking the amount of protein you are giving them. Also, if there are yellow spots in your backyard where your dog is usually doing its business, that might also be because of too much protein in its diet.

How Many Carbs Does My Dog Need

There is no specific required amount of carbohydrates for dogs. AAFCO does not have a requirement for carbohydrates due to traditional preparations of commercial diets.

Commercial dog foods contain enough carbohydrates to meet the daily amount of glucose that is needed. Glucose is needed to maintain the nervous system and keep it functioning normally.

Dry dog foods typically contain 30-60% carbohydrates, with the majority being starch. Grains such as corn, rice, wheat, barley, and oats provide the bulk of starch and are well tolerated and absorbed in dogs due to commercial preparations. Its important to note that a diet without any added carbohydrates will be higher in proteins and fats.

Vitamins are very diverse and perform many different functions in a dogs body, such as the creation of DNA, bone development, blood clotting, normal eye function, and neurologic function.

There are five characteristics for a nutrient to be considered a vitamin:

  • The nutrient must be an organic compound that is not a fat, carbohydrate, or protein.

  • It is a required component of the diet.

  • It is essential in small amounts for normal function.

  • It causes a deficiency or decreases normal functioning when missing.

  • It cannot be naturally synthesized in quantities sufficient to support normal function.

  • There are quite a few vitamins that dogs require from their food. They can be separated into two categories: fat-soluble and water-soluble.

    Fat-Soluble Vitamins

    Vitamin A
    • Fish oil
    • Egg
    • Dairy products

    Guaranteed Analysis And Dry Matter

    A guaranteed analysis of a pet food label indicates nutrient level it as fed where the minimum amounts of protein, fat, minerals, vitamins, and so on, as well as the maximum fiber and moisture content, are provided.

    From a guaranteed analysis, it is possible to see if a specific cat diet meets the minimum recommended nutritional level. Unfortunately, this will not indicate the quality of the nutrient.

    GA is determined by laboratory analysis or computer software with a nutrient content database for all the nutrients used.

    On the other hand, dry matter refers to pet food without any moisture in it. For instance, from the GA, you can determine its dry matter i.e., by deducting the amount of moisture.

    Once you have the dry matter, it is easy to compute the various nutrient level and see if they meet the recommended amounts.

    Dry matter nutrients computation

    For instance, if we use the one for Purina Cat Chow, the GA is as follows:

    Crude Protein
    0.15%

    The dry matter will be 100 less maximum moisture content = 88

    To get dry matter percentage of any nutrient, you should divide the reported nutrient content by dry matter as a percentage.

    For instance, the minimum % of crude fat based on the dry matter is x100 = 13.64%

    Finally, when doing your math, do not forget to factor in your cats weight, age, activities, how easy the source will be digested among many other factors.

    Dry Dog Food High In Animal Protein

    Things You Need To Know About Dog Food Nutrition Labels ...

    As mentioned earlier, crude protein only measures the amount of nitrogen in the food as an indicator of protein. However, nitrogen can also be derived from plant-based and non-food ingredients. This manner of protein measurement is commonly used for kibble.

    It is nearly impossible to know exactly how many percent of the protein is from what source. Vegetable sources of protein are cheaper than animal sources but they are of inferior quality.

    Is The Crude Protein Method Still Relevant Today

    Well, this is a critical question considering that this method was developed over a hundred years ago. Advancements in nutrition and science generally have literally exploded since then.

    There are far better, more modern, and more sophisticated ways to understand the nutritional requirements of pets and other animals these days.

    Plus, the archaic assumption that protein is 16% nitrogen makes this method even more faulty. The nitrogen content in protein isnt constant. Instead, it varies by the amount of amino acids it contains per time.

    A better way to determine nitrogen content, therefore, is to analyze the protein source individually for their amino acid profile. For instance, meat and fish have different amino acid profiles, and, therefore, contain different percentages of nitrogen.

    Another reason this crude protein method is unreliable is that proteins can also contain nitrogen from non-protein sources. The crude protein method does not account for this but science has discovered that this non-protein nitrogen can account for up to 10% of the total nitrogen content in foods. This percentage may vary across foods, though.

    So, putting this in mind, it would mean that whatever is presented as the protein content from crude protein analysis should actually be 10% less than the value presented.

    High Crude Protein Does Not Equal High Quality

    If the protein is poorly digestible, then the excess protein is excreted into feces or fermented into some nasty fecal and flatulence odor compounds like cadaverine and putrescine . If you have dogs that sleep in your room at night, you have likely fallen victim to this crime.

    If the protein is highly digestible , it will be used for structural protein synthesis , synthesis of enzymes and hormones and, finally, deaminated for energy utilization and storage . The excess nitrogen resulting from the deamination is excreted as urea in the urine . High concentrations of urea in the urine will result in your lawn having yellow and burnt spots.

    Why Dog Food Matters

    Back to top

    Make no mistake, food is the most important factor in your dog’s life. Through diet, he has to get everything his body needs: from the energy needed to keep chasing those balls to the incredible array of nutrients that form every tissue and keep every cellular process going, it must all be delivered through his diet. Too much or too little of any one nutrient can quickly cause upsets and if something gets into your dog’s diet that shouldn’t be there, you can be sure that problems won’t be far away. From weaning right through to old age, it is diet more than any other factor that will determine the quality and the length of your dog’s life.

    You owe it to your dog to get his food right but don’t fret, we’re here to help all the way!

    Dogs that are actively exercised for several hours a day naturally burn a huge amount of calories, and their diet needs to represent this. There is a wide choice of working dog foods available, the majority of which are cheap, low grade feeds that, instead of providing extra energy, rely on the owner feeding a lot more to get enough calories in to the dog. There are exceptions, however, but since the best source of calories for dogs is meat, and since meat is expensive, good quality, working dog foods can be fairly expensive. Take a look at our our Dog Food Directory and filter for working dog foods to see what options are available.

    High In Fiber Content

    For anal gland issues in dogs, a high-fiber diet is strongly suggested by vets. Dietary fiber is an essential part of a dogs diet. It is derived from plant-based food that goes through the digestive system without being digested.

    High-fiber diets can help firm up loose stools, which is necessary for draining the glands naturally, preventing impaction and infection.

    There are two types of dietary fiber soluble and insoluble fiber. Soluble fiber dissolves in water, while insoluble fiber does not. But both soluble and insoluble fibers have beneficial functions for the body.

    Sufficient dietary fiber in a dogs food can help in weight management, prevention of hypertension, and control of cholesterol and blood sugar levels, among other health gains.

    Dissolved soluble fiber forms a gel that helps the dog’s digestive system. On the other hand, insoluble fiber collects water into the stool making it easier and smoother to pass through the digestive tract.

    The more common sources of soluble fiber are peas, oats, beans, lentils, carrots, apples, sweet potatoes, pumpkin, beet pulp, kelp, broccoli, flaxseeds, sunflower seeds, barley, and psyllium.

    For insoluble fiber, the following foods are great sources too: potatoes, brown rice, berries, quinoa, wheat bran, whole-wheat flour, nuts, and beans.

    But how much fiber is sufficient for anal gland problems? Most dry dog foods contain a maximum crude fiber of not more than 5%, which is okay.

    Protein In Dogs Diets

    There are many kinds of proteins, which are made of complex, organic compounds. Each type of protein consists of a varying mix of amino acids attached to each other with peptide bonds. Dogs can manufacture some of the 22 amino acids found in their bodies, but need a dietary source for others. Amino acids build body proteins, which in turn function as components of enzymes, hormones, a variety of body secretions, and structural and protective tissues.

    Proteins are in a constant state of flux, always undergoing degradation and synthesis. Some constituent amino acids get recycled, some are excreted, and some are used for energy. In the case of growing or gestating animals, new tissue is created from protein, among other things.

    Protein is a good energy source, providing 3.5 kilocalories of energy per gram of weight. However, not all proteins contain the complete array of amino acids needed by dogs. For this reason, it is important to balance out these deficiencies and/or excesses of amino acids when selecting ingredients for use in pet food diets. Neither corn nor soybean meal is an ideal protein, for example, but, fed in combination, soybean meal and corn complement each other perfectly, because the amino acids which are deficient in one are present in the other.

    The requirements for different amino acids also change as the dog grows and ages. For example, a dog needs only a quarter as much arginine for adult maintenance as he needs when he is a growing puppy.
