Taurine has been in the news a lot in the last few years after a link between grain-free diets and heart diseases in dogs became suspected. The suspicion initially was that a lack of taurine, which is an amino acid, in the diets was causing taurine deficiencies in dogs, leading to dilated cardiomyopathy.
As time has passed, the theories surrounding the grain-free diet link to DCM have changed with new information, but it has brought taurine to the forefront of many people’s thoughts when choosing foods for their dogs. Here’s what you need to know about taurine for dogs and some foods that are great natural taurine sources. So, how much taurine do dogs need?
What Is Taurine?
There’s not a straightforward answer to this question because the answer truly is “we don’t know.” To understand why, you have to understand what taurine is and does. Taurine is an amino acid that is considered to be a “building block” of proteins. 22 amino acids are needed for the body to perform all proper functions.
Of those 22, 12 of them are nonessential amino acids. This doesn’t mean they aren’t necessary, but the body can synthesize them when needed. The other 10 amino acids are essential, meaning the diet must supplement them for the body to have access to them. The 10 essential amino acids are arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Taurine is a nonessential amino acid and can be synthesized by the dog’s body.
How Much Taurine Do Dogs Need?
Not all dogs can synthesize the correct amount of taurine, but there isn’t an exact science behind this. Age, breed, and health status all affect your dog’s ability to synthesize taurine. Taurine supports cardiac, eye, skin, coat, reproductive, and liver health, as well as the immune system.
Only your veterinarian can tell you how much taurine your dog needs. They can perform tests to determine if your dog is taurine deficient and make recommendations based on your dog’s current needs. The good news is that you will be hard-pressed to overdose your dog on taurine from food sources, so here are some of the natural taurine sources to help ensure your dog’s taurine stores stay where they should.
Top 7 Natural Sources of Taurine for Dogs
1. Fish
Fish are one of the best taurine sources for dogs because they tend to be higher in taurine than other meats and are packed with nutrients and omega fatty acids. Salmon, tuna, sardines, rainbow trout, sea bream, and other cold-water species are the best picks for taurine sources. Tuna beats most of the competition with around 332 mg per 100 g of meat.
2. Shellfish
Shellfish is a great taurine source for dogs because it is not just rich in taurine but also tends to be a novel protein for many dogs. This means that it can benefit dogs with allergies to common proteins. The ideal shellfish for your dog include oysters, clams, scallops, and mussels.
3. Eggs
Taurine in eggs is controversial since different studies have found varying levels of taurine that seem to be related to the hen’s diet and supplementation. However, eggs are a lean protein that can be exceptionally affordable for many dog owners. Chicken, duck, quail, and goose eggs are good egg options for dogs, but chicken eggs are the easiest to find and most affordable. Cooking the eggs reduces the risk of foodborne illnesses, and you shouldn’t serve raw eggs to your dog.
4. Poultry
Poultry meats like chicken, turkey, and duck are high in taurine. Dark meat is higher in taurine than white meat, so thighs and drumsticks are better sources of taurine than breasts and wings.
5. Red Meat
Red meat proteins are also good sources of taurine, including beef, lamb, and pork. They are higher in calories and unhealthy fats than poultry and fish, though, so they should be properly portioned and fed in moderation. Raw lamb muscle meat is one of the highest taurine red meat sources, at 310 mg for every 100 g of meat.
6. Organ Meat
Organ meat is the nutrient-dense tissue that comprises various organs throughout the body. The best organ meat taurine sources are heart and liver, with chicken liver beating beef liver by around 40 mg for every 100 g of meat. Chicken liver weighs around 110 mg, and beef liver weighs around 68 mg.
7. Goat’s Milk
Goat’s milk is lower in taurine than the other protein sources discussed here, but it contains some and tends to be easier for dogs to digest than cow’s milk. However, goat’s milk is high in calories and fat, so it should be fed in moderation. It is packed with probiotics and is often considered a food that helps support digestive health, although some dogs may experience stomach upset with goat’s milk.
In Conclusion
Taurine supplementation is not necessary for most dogs, but your vet can help you determine if your dog requires this supplementation. The best thing you can do is to feed your dog a balanced diet that meets AAFCO guidelines to ensure your dog’s food is meeting all of their needs. The science is still out on the connection between grain-free diets and DCM in dogs, and it isn’t believed that taurine levels in the food play a part. However, it’s a good idea to feed your dog a protein-rich diet that helps support taurine levels and overall health.
