What is DCM ? (pt 1)

I am sure you have heard this in the news recently. DCM killing dogs and the potential link to grain free kibble. But, what is DCM? It’s official name is Dilated Cardiomyopathy. This is a heart that is enlarged and unable to function properly. It is not strong enough to pump the blood and therefore the heart chambers fill with fluid. Basically, it is congestive heart failure.

Symptoms of DCM can be heart murmur, increase in blood pressure, weakness, exercise intolerance, cough and collapse. If you are concerned that you are seeing any of these in your dog, please contact your vet.

What causes DCM and how does nutrition play a role?

Some breeds have a genetic predisposition for DCM. These can include Doberman, Boxer, Newfoundland, Scottish Deerhound, Irish Wolfhound, Great Dane and Cocker Spaniel. Large older male dogs form the largest group with DCM. The typical age for a dog to be diagnosed with DCM is between 4 and 10 years.

However, what we are seeing in the news, are breeds not normally associated with a genetic predisposition, being diagnosed with DCM. The second largest group being mixed breeds. ( the largest is Golden Retrievers) But what is most disturbing, is that 93% of these dogs have been on “grain free” kibble. Now wait a minute! Aren’t they supposed to be healthier than regular kibble? Don’t we pay a premium price for these foods? Let’s take a look at what is on the labels.

Here are the ingredients in a well known grain based dog food.

Corn, meat and bone meal, corn gluten meal, beef fat, soybean meal and poultry by product meal.

Here we have a diet high in grain and carbohydrates. Now I am not going to get into how inappropriate these are for your dog, just know that they are.

These are the ingredients in a well know grain free kibble.

Beef, Pork, beef meal, red lentils, pinto beans, green peas, green lentils, chickpeas, yellow peas and lentil fiber.

This looks much better, right? But, what we have here is a diet very high in carbohydrates and legumes. While legumes have a fair amount of protein, in this case, the protein from the lentils is greater than the protein from the meat. So why, you may ask, is this a problem? Protein is protein, right? Wrong!


Protein is made up of chains of 22 amino acids, 8 of which are essential. This means that we have to get those amino acids from our diet because our bodies, and our dogs bodies, can’t make them. Animal sources, ie: meat and eggs, are a source of what we call complete protein. Legumes are not. What do I mean by a complete protein? A source that contains all of the essential amino acids. Legumes do not have all of the essential amino acids and are therefore incomplete. Now, it is possible to make legumes complete by combining them with other foods that have those missing amino acids in them. But, I digress.

Why are legumes not a good choice for your dog. Because your dog is a carnivore, not an herbivore or even an omnivore. Plain and simple. Dogs may be able to survive on beans , peas and lentils. But they will not thrive the way they will on a meat diet. Dogs have sharp pointed teeth and a short digestive tract with a hydrochloric acid based digestive system. They do not have a second stomach where they can ferment legumes, or grains for that matter. They are not a cow.

Back to the grain free diet and DCM. What is causing it?

Research is being done right now to answer that question, and they are struggling with it. What do we know so far? Dr. Josh Stern at UC Davis in California, is one of the researchers looking into this. He has found that some instances of DCM were linked to a diet high in peas and legumes. Also, potatoes and sweet potatoes are questionable. However, it is taurine that is standing out. Taurine is a Sulphur containing amino acid that is essential in cats but not dogs.Without it, the heart muscle becomes weak and that’s when DCM can develop. Dogs can make some taurine IF they have adequate levels of cystine and methionine, two more Sulphur containing amino acids. However, on the grain free diets, dogs appear to be deficient in all three amino acids, one reason possibly being that legumes lack methionine. Good news right? We have identified the problem. Not so fast. Because not all of the dogs had low taurine levels. Confused yet? If so, you are not alone.

So what are dog owners to do? Until we know more, I am telling people to feed a species appropriate raw meat diet. Especially heart meat. Chicken, lamb, goat, beef or turkey. All are equally full of taurine. I say raw heart because taurine is very sensitive to heat and should not be cooked. Freeze dried or air dried seems to be OK too.

Above is a species appropriate raw diet that I prepared for my dogs. It contains New Zealand green lipped muscles, chicken back, green tripe, grass fed beef, goat heart and a sprinkle of bee pollen.


Flea and Tick Treatments

Ticks can be problematic in the forest after rain.

But, I would say that ALL chemical flea and ticks treatments will cause neurologic events, and more. They can also cause liver damage, organ failure and death. The insert says to wear gloves when applying, not to pet the dog until it dries and if you get it on your skin, to wash it off completely and call poison control. Now, I am going to let that sink in for a moment. So, if this is a poison for us, how is it not a poison for our dogs? Something else that people don’t realize until I tell them is that the fleas and ticks still have to bite your dog in order for it to die. The flea and tick treatment is in the blood of your dog. Fleas and ticks are after your dogs blood, the little vampires!

I understand that they are a problem in most areas, mine included. I will admit that I struggle with fleas also. So what can we do to get rid of them without resorting to chemicals. First, is to feed a raw , species appropriate diet. Keeping the immune system strong is the first step. Invest in a good vacuum cleaner and a flea comb. I have used amber collars with good success and flower essences too.

Here is a great article with strategies to help in the battle against the little vampires.

Heart Problems in Dogs

There has been a lot in the news lately regarding heart problems in our dogs and “Grain Free” pet foods. In truth, these designer foods are no better and probably worse than their grain based cousins. They have a higher sugar content and the grains are replaced with legumes, peas, potatoes and lentils. All are very high in carbs. Grain free does not equate to carb free. In truth, your dog needs a species appropriate raw diet.

This article, written by Kasie Maxwell from SFRaw does a very good job of explaining the problem.
