How Poor Nutrition Can Shorten the Lifespan of Your Pet (And What You Can Do About It)

As pet owners, we all want our pets to live long and healthy lives.

However, there are some factors that we as pet owners have no control over.

Most notably...genetics.

Thankfully though, there are many factors that we DO have control over.

Your pet’s nutrition is the #1 thing you have absolute control over and it’s the biggest preventative care measure you can address.

The reason this is so important, is that around 80% of your pet’s immune system is in their gut.

That means if your pet is allergic to anything in the diet you're feeding, there are a lot of negative health consequences that can develop as a result.

Pets can exhibit chronic ear infections, engage in chronic licking / chewing of the feet, or scooting their bum across the floor due to anal glands being swollen...preferably when company is over.

They’ll occasionally even exhibit upper respiratory congestion, just like people do during the height of spring and fall allergy seasons.

Many pets are affected so severely, that they'll experience seizures and develop a condition called, “idiopathic epilepsy”.

An improper diet triggers severe inflammation and can trigger a snowball effect of health issues like the ones just discussed.


Inflammation is the root of many chronic diseases and it most definitely shortens the lifespan of your pets.

Therefore, it’s EXTREMELY important to do everything possible to give food and treats that aren’t going to trigger inflammation.

Ingredients I recommend avoiding are:

  • Corn

  • Wheat

  • Soy

  • Dairy

  • Fish that isn't hydrolyzed

*Chicken may also have to be avoided, as some pets are extremely allergic to it too.

Many pet owners do a great job of feeding high-quality food without inflammatory ingredients.

However, problems can still develop even from the occasional table scrap or unhealthy treat.

They can easily make the mistake of giving a piece of bread, some fish, or part of a cheeseburger, thinking: "It won’t hurt's just a bite.".

Unfortunately, over the years I've found that just a small “treat” can trigger severe inflammation and allergy problems.

We can see the bad skin and the seizures manifest with our eyes, but what we can't see is all the damage that chronic inflammation causes our pets beneath the surface.

Here are some steps you can take to help decrease inflammation in your pets:

  • Supplement with coconut oil (it's rich in medium-chain fatty acids, which makes it a great anti-inflammatory agent)

  • Supplement with omega-3 fatty acids (which can be found in krill oil, fish oil, or flaxseed oil)

  • Give a high-quality probiotic (to help maintain good bacteria in the gut)

If you haven't read my post on the benefits of probiotics, check it out here.

I do realize that incorporating all these supplements can seem pricey, but it's definitely worth it!

The way I like to explain it, is that it's like purchasing health insurance for your pets.

Invest a few dollars each day in supplementation and it'll save you a ton of money in the long run by avoiding unnecessary vet bills down the road.


Please don't give your pets city water from the faucet or a water hose, as it's full of things that are bad for them.

City water is treated with fluoride and also doesn't filter out pharmaceutical drugs that are flushed down toilets or poured down sinks.

These things can only be filtered out through a process called, "reverse osmosis".

So, unfortunately, not even a Pur or Brita filter will help you filter out pharmaceuticals.

I don't know about you, but I don't really want my pets (or myself) to be ingesting water that's contaminated with anti-depressants, hormone therapy drugs, or statin medications with all kinds of crazy side effects.

The easiest way to avoid this, is to invest in a reverse osmosis system for your kitchen sink.

There are many options out there, but the easiest solution is just to call your nearest Culligan location and have them come out and install one for you.

(They even offer monthly payment plans.)

If you're on well water, then you could potentially be safe, but I'd have someone like Culligan come out and test your water first to ensure that it's safe for both you and your pets to be drinking.


When all else fails, try giving your pets a "cleansing diet" to improve their health symptoms.

If your pet is ever in really bad shape, I highly recommend a cleansing diet where you feed them ONLY green beans and sweet potatoes for 6 weeks straight.

This is by no means a balanced diet, but it will help many pets to shed chronic inflammation, so they can begin to heal and start feeling better.

Many veterinarians will recommend various antihistamines to battle the inflammation since it often manifests via allergies.

Antihistamines are the drugs of choice for most humans who suffer from allergies and inflammation (like Benadryl, etc.).

However, the chemical responsible for pet allergies is a substance called interleukin 31 (also known as IL 31) and antihistamines have no effect on IL 31.

There's a popular prescription drug called Apoquel that specifically blocks IL 31, but it's very expensive and in my experience, the effects seem to lessen over time.

That's why I firmly believe that Hippocrates (the father of modern medicine) had it right when he said, “Let food be thy medicine and medicine be thy food”.


The key takeaway I want you to leave here with today is that inflammation is the primary trigger for many chronic diseases & that it can also lead to cancer.

Fortunately, the primary thing responsible for causing inflammation is something that YOU as a pet owner have complete control over: The diet!

This is the single most important (and easiest) way to prevent health issues from developing.
