Is a raw diet too much protein for dogs

The Dangers of High Protein Dog Foods

By Ashley Gallagher, DVM

Choosing what to feed your dog can be an overwhelming decision. Pet food stores are packed with row after row of different brands of food all containing clever marketing slogans to convince you they are the best for your dog. Many of these dog foods boast about containing extremely high levels of protein that claim to satisfy your dogs instinctual need for meat as well as make them healthier and live longer.

Are Dogs Carnivores?

Marketing tactics by some pet food companies have fueled a common misconception among pet owners that dogs are obligate carnivores and require a diet that consists mostly of meat. This is not true. Dogs, like people, are omnivores and do best with a balanced diet of protein, carbohydrates, and fat. Excessive protein consumption is unnecessary for dogs at best and for some dogs with medical conditions can actually be harmful.

Proteins are the building blocks of the body and an absolute necessity for daily function. However, when a dog consumes too much protein in a meal it cannot all be utilized at one time, nor can it be stored for later. The body will then excrete the excess protein through the kidneys and out of the body via urine. Thus the quality of the protein actually becomes more important that than actual amount as a high quality protein is more bioavailable and can be better absorbed by the body.

Another issue is that the meat in these diets acting as the protein source contains other nutrients that you do not want in excessive amounts. For example, when a diet is mostly meat it becomes very difficult to maintain a proper calcium-phosphorus ratio. When this ratio is out of balance disruptions in bone growth or kidney damage can occur. Well formulated dog foods have an appropriate balance of protein, fat, and carbohydrates to prevent this from happening.

Is Excessive Protein in Dog Food Bad for My Pet?

Protein is a calorie dense nutrient and many of the high protein diets are extremely high in calories and can quickly lead to weight gain. With over 50% of dogs in the U.S. considered overweight or obese, dog owners need to be aware of where those extra calories are hiding. If a dog has kidney or liver issues consuming too much protein can increase the workload on these organs and upset the balance of nutrients leading to exacerbation of disease.

Rather than look for a dog food that contains excessive levels of protein you should find one that is specifically formulated for your dogs lifestyle, life stage, and size. A working sled dog, for example, will have significantly different nutrient and caloric requirements than the average pet dog that ventures outside for a few walks a day and spends the rest of the time lounging. These two dogs should not be fed the same diet.

Puppies, meanwhile, require more protein than adult dogs because their bodies are busy growing. Among breeds of puppies there are different requirements for nutrients as well. For instance large breed puppies like Labrador retrievers need a much different diet than a Yorkie for optimal growth. Feeding large breed puppies something that is too high in protein may make them put on weight too quickly causing abnormal joint development and making them more prone to issues like arthritis in the future.

The safest diets are those that have been developed by pet food companies that invest in scientific research, consult with veterinary nutritionists, and perform feeding trials to develop their diets. This will provide a pet food that is properly balanced without any excess nutrients that are unnecessary and in some cases harmful for your dog.

Can Dog Food Have Too Much Protein?

Of all the nutrients in dog food, protein is the one that gets the most attention. We know its crucial to dogs development and lives. But can you have too much of a good thing?

The Dog Food Advisors nutritionist, Laura Ward, discusses the highs and lows of protein in dog foods and how much is too much.

__________________________

If youve checked out the AAFCO Nutrient Profile, youll know that the minimum protein requirement for adult dogs is 18% and for puppies its 22.5%. This is expressed on a dry matter basis or DM, a way to compare foods of different moisture (such as a wet food and a dry food) by theoretically removing the water content.

However, theres currently no nutritional maximum for protein so what does that mean for our dogs food? How much protein is too much?

How high is high-protein?

We consider any diet with a DM crude protein content of more than 28% is high-protein. It isnt unusual, however, to see protein levels above 35%, or even over 40% in dry foods. In fresh and wet foods this is often greater, at around 60% DM. This high protein bracket, therefore, covers a wide range of protein possibilities.

Benefits of high protein in dog food and when to be cautious

Protein is linked to palatability for dogs, so high-protein foods are usually super tasty. Dogs will often choose a high-protein food over a lower-protein option, so if you have a fussy eater, high-protein food can be a great choice. There are other scenarios too where higher protein is particularly valued.

For active or working dogs, the protein they need for maintenance is increased. Not only is there a greater need for the replenishment of muscle tissues, but other changes in the body require proteins from the diet too. This is because endurance activities require more efficient delivery of oxygen and nutrients to muscles, which the body becomes conditioned for, just like with human athletes.

These changes include increased blood volume, red blood cell quantity, and increases to other parts of the body cells used for energy generation. The protein building blocks for this come from increased protein being delivered through the diet.

Its also important for senior dogs to have a high-quality source of protein in their diet. Protein, making up a larger proportion of the calories in a senior diet, can support their lean muscle and help to avoid the muscle-loss associated with ageing. Moderate- to high-protein wet or fresh food options can be good choices for senior dogs, as they improve hydration, are very palatable, and are also soft on weaker teeth.

Weight-loss is another situation where protein is important. The energy (or calorie) content of the food is carefully controlled to aid weight loss, but its also important to support muscle. A good quality protein supply and higher-protein content in the diet is essential to avoid muscle wastage.

However, dogs are more likely to eat more of a high-protein diet, which is counterproductive for weight loss. High-protein diets at the higher end of our high protein range (more than 35% DM) are often particularly nutrient dense and can be ill-suited for weight loss. Dogs need only a small quantity of these foods which, when combined with weight loss measures, can leave dogs fed a high-protein diet which isnt designed for weight loss, feeling hungry.

For pregnant and nursing dogs, protein is a crucial element of the diet. During these phases, the requirement for proteins, through changes to the body and the development of puppies or the supply of milk, is great. AAFCOs nutritional profile for growth is most suitable for pregnant and nursing dogs, to represent this increased requirement. High-protein foods can be a great choice during this time.

With diabetic dogs, its the carbohydrate content of food which is the greatest focus. As diabetic dogs cannot safely regulate their response to blood sugars, carbohydrates should be limited in the diet. This generally means that energy is primarily supplied by fats and proteins in the diet to minimise peaks and falls in blood sugar after meals. High-protein and low-carbohydrate foods are recommended, but your veterinarian will advise further what this looks like for your dogs diet.

In the case of any susceptibility to kidney problems, or renal insufficiency, take advice from your veterinarian before feeding a high-protein diet. Although its important for dogs with renal insufficiency to still have a high-quality source of protein in their diet, diets which contain a moderate, rather than high, protein content are often more suitable.

Studies have shown that protein is not connected to the progression of chronic renal failure, however, recent studies have also found high protein (46%) can be linked to an increase in markers of kidney dysfunction. Although veterinary advice now doesnt call for protein restriction, it often recommends avoidance of excessive dietary protein.

Whats wrong with low-protein dog foods?

A real low-protein diet is only available when prescribed by a vet, as feeding a low-protein diet without medical need could cause deficiency diseases in a healthy dog. There are foods, however, which meet AAFCO protein requirements without supplying very much extra protein. These foods supply the majority of the energy from fats and carbohydrates.

This is often associated with lower quality or cheaper foods, as protein is often a key driver of cost in a dog food recipe. As protein is linked to palatability in dogs, lower protein foods can be less tasty.

Carbohydrates are broken down differently to proteins, into sugars. The carbohydrate source in the recipe determines how the blood sugar is affected. For foods which are high on the Glycaemic index, a peak, followed by a fall in blood sugar is seen. Although not an area which has been sufficiently studied, this is thought to be linked to fizzy and lethargic behaviour like children fed sugary foods.

Summary how important is protein in dog food?

The quality of the protein in a food is far more important than the quantity. A protein source which supplies all of the amino acid protein building blocks in the correct quantities and in a digestible and accessible form is the goal.

There are certainly benefits to be gained by supplying high levels of protein in a dogs diet, but the effects of some of these super-high-protein foods are not well studied yet. If in doubt, feeding a moderately high protein food to begin with of 28% to 30% DM protein and monitoring your dogs reaction is recommended. Remember, you can always ask your vet about changes to your dogs diet.

High Protein Diet for DogsHow Much Protein Does Your Dog Need?

Does your furry buddy howl at the moon? No? Well, we are on the same pagedogs are not wolves, although, at times, they certainly think they are. Despite the popular opinion that these two species should eat similar food, they dont have the same food requirements.

A common misconception has grown around the theory that dogs need lots of protein to satisfy their meat needs. Canines are not obligate carnivores, despite what youve heard from many pet food companies.

Finding the perfect balanced nutrition for your furry one is difficult, and you do need to use your Sherlock Holmes skills to rule out harmful products from your pups diet. There are a lot of excellent formulas out there, but you need to dig deep.

First, start with the specific nutritional needs of your pooch. Highly active dogs will have different diet requirements from pups, whose primary duty is to walk to the food bowl and back. Even these lazy couch potatoes need to have some exercise during the day, but the activity levels need to be reflected in their feeding.

All ingredients should be taken in moderation, and the same goes for proteins. Read on to learn how much protein is safe for your pet and why balanced nutrition is so important.

Our evaluation

Our team of avid dog lovers is here to help you. We investigate each dog-related topic to the fullest, with the aim of providing you with verified information. If you are not certain how much protein your dog can have, there is someone who knows.For this topic, we chose to consult

1. Three veterinary nutritionists
2. Dog parents
3. Dog lovers community

Veterinary nutritionists gave us their professional opinion on the matter. Years of experience have resulted in an in-depth knowledge of how much protein is sufficient for your pup.

What Are the Typical Mistakes and Misconceptions among Dog Owners

Dogs dont need a diet that consists mostly of meat. Thats the greatest misconception circulating in the dog world. Dog food companies have instilled this idea as part of their marketing strategy. Just like us humans, our little friends are also omnivorous. You must have noticed this yourselfwhenever you leave them unsupervised, they eat anything they find in their way.

This misconception also stems from the fact that dogs are related to wolves, which are carnivorous animals. After many years of evolution, these two species have gone different ways, and while wolves remained carnivorous, dogs have developed the ability to digest plant-based nutrients.

How Much Protein Should Be in Dog Food

Proteins need to be part of every dogs diet. Proteins contain amino acids, which are crucial for their nutrition. The lack of proteins can lead to severe issues such as

• Weight loss
• Sickness
• Fatigue
• Rough coat

The problem with feeding your dog high-protein formulas is that your pups body cant digest too much protein at once. All excess protein can either be burned in energy or turned into fat. For dogs who like to sleep and rest day in day out, too much protein can lead to severe health problems with

1. Kidneys
2. Liver
3. Obesity
4. Immune system
5. Diarrhea

Puppy pups need a greater amount of protein in their diet because their bodies are developing. However, you should be careful with large breed puppies. If they gain too much weight, it will put enormous pressure on their growing spine and joints. The same goes for dogs who have short legs. Their nutrition needs to be tailored not to stress their joints. Dogs who put on too much weight are less likely to be active, and thus will turn into a dog version of Garfield.

So its difficult to say whats the exact amount of protein that your pooch should get. It all depends on their breed, activity, lifestyle, size. According to our research, a rough estimate would suggest that puppies should get around 29 percent of protein. Adults require approximately 18 percent dietary protein along with all amino acids that their body needs.

The ten most essential amino acids for our dogs are:

• Lysine
• Arginine
• Threonine
• Histidine
• Valine
• Isoleucine
• Leucine
• Tryptophane
• Methionine
• Phenylalanine

Your task is to find food that contains as many amino acids as possible, as each one of them contributes to healthy development of your pooch.

You should also know, its not always the amount of protein that matters, but its quality and digestibility. Make sure that your pup gets protein from high-quality ingredients. The food youre giving to your pet must contain both animal-based and plant-based proteins.

Protein is burned in the liver, and the excess protein is filtered in the kidneys. High-quality protein does not produce much waste. Poor quality protein is not easy to digest, and it puts too much pressure on kidneys. The liver needs water to process protein, so we advise all dog owners to mix dry food with canned food. Extra moisture found in the wet food will be beneficial for them, and it might prevent liver disease.

Can protein sources cause allergies in dogs?

While pet owners usually suspect that their pooch is having issues with grain, the actual problem can just as easily be protein-based. Chicken and beef are proclaimed the biggest causes of dog allergy. Even though they belong to high-quality protein sources, in case your pet is allergic or sensitive to beef or poultry, look for the products that dont contain these ingredients.If your pup suffers from allergies, we advise you to consult with your vet to help you find the perfect diet for your buddy.

Where to Find High-Quality Protein

Our hairy companions are omnivorous. We need to give them protein if we want to keep our dogs healthy and strong. Search for the food with a high biological value that your pooch will digest easily. In the list below, youll find the kinds of food that have this value.

Top-quality food brands always use different sources of protein. So youll see that apart from lamb, beef, or poultry, they almost always add extra protein sources from eggs, fish, or cheese. So, lets see how much protein we can find in these ingredients.

Meat as Protein Source

Meat is an excellent source of protein, but you need to make sure you find products that contain real meat. Despite the claims of dog food companies, always read the ingredient list before opting for a certain formula. Meat thats most often included in high-quality formulas is:

Meat by-products are slaughterhouse waste. They contain some proteins, but theyre usually difficult to digest. If you can afford it, always go with formulas that contain real meat. Meat by-products typically contain:

• Feathers
• Horns
• Claws
• Beaks
• Hooves
• Hair

Fish as Protein Source

Fish is used in many high-quality products as it is rich in Omega 3 fatty acids. These acids maintain healthy skin and provide your pup with a lustrous coat. Your pup will be proud of their look, and they will want to have some friends over, just to brag.

Eggs as Protein Source

Believe it or not, dogs can sometimes get more proteins from eggs than meat. You can give eggs to your pup as part of their homemade meal, as long as theyre cooked.

Balanced Diet

Your beastie must get protein from different sources. If they continuously eat the same food, based on the same protein sources, they can grow a sensitivity to it. As we have already mentioned, the best formulas are the ones that mix animal and plant-based proteins. Several factors also influence well-balanced nutrition, and those are:

1. Vitamins. Vitamins contribute a lot to your poochs health, especially their eyesight. The formulas youre feeding to your dog should contain around one percent of vitamins.
2. Carbohydrates. Regular intakes of carbs will keep your canines colon healthy. They contain fiber that aids digestion and regulates colon bacteria. Carbohydrates are excellent energy providers.
3. Minerals. If you want your pups bones and teeth healthy, look for food that contains about two to four percent of minerals.
4. Fat. Your dogs food should contain from ten to twenty percent of fat. It promotes healthy coat growth and a strong immune system.

Below youll find two food formulas that we selected for you. They can serve you as a model while youre searching for your poochs perfect diet.
