As animals age, their dietary needs and preferences also change. Aging pets need more care and specific nutrients in their diet. Taurine and Carnitine and two of those essential nutrients that your aging pet needs.

As our pets age, we all want them to stay strong and healthy. However, some dogs can develop heart problems and mobility issues. Taurine and Carnitine are two amino acids that are building blocks for a healthy heart and muscular system. By simply switching your pet’s food to something high in Taurine and Carnitine, you can prevent heart issues such as Dilated Cardiomyopathy (DCM).

After reviewing the available options, we have compiled a list of the best options that contain taurine and carnitine.

Buyer’s Guide

Being a responsible pet-owner, one should be well-informed about what goes into their dog’s diet choices. As our pets age, they tend to rely more on their diets for some essential nutrients. This is especially true for senior dogs who might experience health issues if not given a proper diet. Most dog food brands offer a similar set of ingredients, but there are some key differences that set apart the best from the rest.

In order to understand the benefits of taurine and carnitine, keep on reading.

What are Amino Acids?

Amino acids play an essential role in muscle development and tissue repair. There are twenty different amino acids, out of which nine are considered essential. These essential amino acids play an important role in many vital processes and are obtained from food. As a result, if there is an essential amino acid deficiency, it can impact the nervous, immune, digestive, and reproductive system of your dog.

Essential amino acids include:

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

What is Taurine?

Taurine is an amino sulfonic acid that is highly concentrated in the heart, eyes, and brain. Although, taurine is not considered essential for dogs, there is no factual evidence of whether dogs can make enough taurine or not. Taurine works to ensure cardiovascular health and is essential for dogs that are susceptible to cardiovascular issues.

What is Carnitine?

Carnitine usually refers to the amino acid, L-carnitine which is responsible for energy production and brain function. However, it is umbrella term for L-carnitine, acetyl-L-carnitine, and propionyl-L-carnitine. Your dog needs L-carnitine to produce energy at a cellular level. Most dogs can have trouble getting enough carnitine from their diet and might need supplements.

L-carnitine is responsible for energy production in dogs. Carnitine basically carries fatty acids to cells, where they are broken down to create energy in the form of ATP. If a dog has a carnitine deficiency, the heart does not have enough energy to pump blood to the body. As a result, the heart’s beating rhythm could also be disturbed.

Dilated Cardiomyopathy (DCM) in Dogs

A gradual degeneration of the heart is referred to as cardiomyopathy. Due to compromised heart health, the muscles of the heart become thinner over time. These thin muscles can stretch due to the blood pressure in the heart. As a result, the heart becomes enlarged due to dilated cardiac muscles. This condition is common among large-breed dogs such as the Doberman Pinscher, Great Dane, or the Irish Wolfhound.

While genetics play a large role in the development of DCM in dogs, there are other facts that should be considered as well. Your dog’s diet can also play a large role in determining their overall health. DCM has also been linked with taurine deficiency on dogs, while L-carnitine was found to be low in dogs genetically predisposed to DCM.

The signs and symptoms of DCM in dogs include:

  • Loss of appetite
  • Increased heart rate
  • Pale gums
  • Breathing difficulties
  • Coughing
  • Weakness
  • Fainting spells

How to Naturally Increase Taurine and Carnitine Levels

If your dog has no underlying health issues but you want to increase the amounts of taurine and carnitine in their diet, you can either:

  • Feed your dog a diet that has added taurine and carnitine.
  • Look for food that has natural sources of taurine and carnitine.

There are many foods that are naturally rich in taurine and carnitine.

Natural sources of taurine include meat and eggs, but organ meats are also high in taurine. The ingredients you should look for to increase taurine naturally are:

  • Shellfish such as oysters, clams, and mussels.
  • Fish (Whitefish and Tuna are high in taurine)
  • Dark meats such as turkey and chicken
  • Organ meats such as chicken liver and beef liver

Carnitine is predominantly obtained from red meats in your dog’s diet, but it can also be found in milk, fish, and eggs. Red meats high in carnitine are:

  • Beef
  • Lamb
  • Pork
  • Venison

What to Look For in Foods Rich in Taurine and Carnitine

With the recent spike in cases of DCM in dogs, many pet food brands now include taurine and carnitine in their formulas. With that being said, just because a food contains taurine and carnitine does not make it the healthiest option for your dog. There are certain things you need to consider when purchasing food for your dog.

1. High-quality Meat Protein

Dogs are carnivores and need high-quality meat in their diets to thrive. You should look for dog food with whole meat listed as the first ingredient. Meat is biologically appropriate and a rich natural source of taurine and carnitine among other amino acids. If your dog has no health concerns, feeding them a diet rich in meat protein can also provide them with the necessary amounts of taurine and carnitine. Meat also contains all essential amino acids so you can be sure your pet is getting complete and balanced nutrition.

2. Meat Type

If you are looking to add taurine and carnitine to your pet’s diet through food, you should also consider the type of meat. We have already discussed the natural sources of taurine and carnitine above. In conclusion, recipes that have seafood, organ meats, and eggs are good for adding taurine. However, carnitine is found primarily in red meats.

3. Healthy Fats

Your dog’s food should contain the proper amounts of Omega-3 and Omega-6 fatty acids. These fatty acids come from sources such as fish oil. Your dog’s food should contain fats in moderate amounts.

4. Easily Digestible Carbohydrates

Many pet-owners are switching to grain-free diets as they believe that grain-free diets are better for their pets. Grain-free diets are not a necessity unless your pet is allergic to grains, and sometimes also use fillers to substitute for the lack of grains. Many grain-free foods may use starches and legumes to bulk up the food, rather than provide balanced nutrition.

If you see potatoes and peas listed in the first two ingredients, you should be vary of buying these recipes. Recipes that include chickpeas and sweet potatoes are a much healthier alternative.

5. Meets the AAFCO Requirements

Pet foods that say “complete and balanced meal” on the label meet the AAFCO requirements for balanced nutrition for dogs at a particular life stage.

Grain-Free Diets and DCM in Dogs

Over the past two years, there has been much controversy regarding the relationship between grain-free diets and DCM in dogs. Due to a rise in DCM cases among dogs, the FDA began an investigation to determine the cause. Although the study revealed no cause-effect relationship between grain-free diets and DCM, it became a cause of worry for many pet parents. Although, one should note that in many of the reported cases, the dog foods listed contained high amounts of potatoes and multiple legumes.

While grain-free diets can be a great option for pets that have digestive sensitivities or allergies, the same cannot be said for perfectly healthy pets. You can choose a grain-free diet for your pet but it is important to consider the ingredients before making a purchase. High-quality grain-free formulas do not use starches to bulk up food, but use real meat or quality protein sources as an alternative to grains.

Carnitine can boost your senior pet’s energy levels and aid them in maintaining a healthy weight. Your senior dog will be healthy and strong with the addition of carnitine into his diet.

Is a raw diet richer in taurine and carnitine?

Most dog foods offer a diet richer in carbohydrates rather than protein. That’s why many pet parents prefer a raw diet over processed foods. It’s closer to a dog’s ancestral diet with proteins being a suitable source rich in all kinds of amino acids.

Can my dog have too much taurine?

Although studies on the subject are limited, the chances of your dog overdosing on taurine are low. Even taurine taken in amounts above the daily recommended doses is well tolerated. If you suspect any adverse reactions due to an overdose, contact your vet or an emergency facility.

When should I start giving my dog carnitine supplements

If your dog has any genetic history of DCM, you should consult a vet about the issue. Your vet can run your dog’s bloodwork to check for any deficiencies. If your dog has symptoms of a carnitine deficiency, you can give them supplements after consulting your vet.

Can my dog have too much carnitine?

As with taurine, it is highly unlikely for your pet to overdose on carnitine. Even L-carnitine taken in high doses can safely be excreted by the body. You should take your pet to your veterinarian if they have any adverse reaction or your suspect an overdose.

Are there any side-effects of giving my pet taurine supplements?

Dogs appear to have a high tolerance for taurine. You can either give the supplements as is, or mix them with your dog’s food. After the first dose, your pet can experience minor vomiting. Taurine supplements usually stop working after 24 hours but the effects can last longer in pets who have liver or kidney disease.
