Houston, we have a problem

Brace Yourself.
Pet Parents, hug your fur baby close- were you aware that the rendered meats used in mainstream pet foods contain the flesh of diseased stock yard animals, euthanized cats, dogs and horses, slaughter house scraps, and can even include road kill?

Boiling these scraps at 280F produces the slurry that gets extruded into a piece of dry kibble, which can end up in your best friend’s bowl.

And here’s the kicker: because euthanized animals are used, there’s a risk that Pentobarbital can end up in your dog’s food.

Step into the cold.
Freeze-drying the same fresh meats you would throw onto your Sunday grill, is a new way to look a pet nutrition.  It’s also good way to ensure that your canine companion is getting food that is only a few steps away from what they would eat in the wild.

Because freeze-drying relies on lowering the temperature and removing moisture from meats during a flash freezing and vacuum process, it produces a versatile, low carb and shelf stable kibble, which can be reconstituted as a meal with a little bit of water, or used as a dry treat.

No doubt, every Pet Parent wants to know that their doggy is eating the best food, and sometimes it can be tough to decipher if rendered meats are being used.  Look for the clues: if you see the terms ‘meal’, ‘by product’, or ‘animal fat’ on a bag of your dog’s food, you may want to give that manufacturer a call and investigate further.

Furthermore, make an assessment as to whether the ingredients in your pet food are Species Appropriate.  For example, do dogs in the wild typically consume, tapioca, glycerin and barley?

Be the Hero your dog thinks you are.  Feed Raw.

*** For all you Pet Food Nerds out there: download the e-book called ‘Essential Rendering’ by the National Renderers Association.  There are in fact some fantastic uses for rendered meats: given that they are high in nitrogen, they can be utilized effectively as fertilizers and soil conditioners.

A brief primer on canine metabolism, health and longevity 

Thinking about caloric control.

Okay, so, ‘intermittent eating’ is just another way of gaining insight into what fasting or intermittent fasting is really teaching us.  Consider this: dogs in the wild don’t eat three meals a day- in all likelihood, they may eat one meal every three days!  We’ll tackle in a moment whether or not this is actually a good thing.

For those new to fasting, it really isn’t the same thing as starvation- rather, it describes an extension of the period of time without food, or techniques for controlling caloric density.  That could shake down to only feeding your doggy once per day, or having a 6 hour window of time where they eat multiple meals, and an 18 hour window of time where no caloric consumption occurs.  Now, why would anyone want do this for themselves, or for their furry friend?  Let’s explore.

Should I fast my best friend?

It’s a pretty well understood scientific constant that controlling calories by an overall reduction, or by extending the window of time without eating, helps just about any organism (worm, bird, primate, canine) not only live longer, but behave and appear more youthful when they are older.[1]

Ancestrally (i.e., before the advent of agriculture) both dogs and humans lived through cycles of feast and famine. It’s only in the modern epoch where Pizza and Pizza flavored doggy treats are readily available, that we and our canine companions can remain constantly in feast mode.

Interestingly, you may observe your dog ‘intermittently eat’ if they are not feeling well, or if their level of activity is lower for some reason.

Research demonstrates the favorable effects of fasting, insofar that during periods of time without food, mitochondria release fewer free radicals.[2] Inflammation underlies many degenerative diseases, and fasting has been shown to decrease the incidence of cancer,[3] [4] [5] mitigate or reverse arthritis, cognitive decline,[6] and Type II diabetes.[7]

Additionally, fasting for 48 hours or longer has been shown to protect normal cells, but not cancer cells, from the toxic effects of chemotherapy in humans.[8] So far, less is known about this phenomenon in Veterinary Medicine, but it could be worth validating for companion animals with cancer.

Well, specifically, what should I do with my doggy at home?

Here’s the take-away: every Pet Parent reflexively wants to be the best steward of their doggy’s health.  That said, obesity and over feeding in dogs is common.  The use of ‘intermittent eating’ and caloric control can be an effective strategy for keeping a dog lean, and helping them to perform and feel better as they age.

For those who wish to explore fasting with their fur baby, one can start with a gradual reduction in overall calories and observe the effects- modest weight loss is one anticipated outcome.  Another technique can be to feed normally, just every other day.

Some find it easier to adjust calories by time period, for example, by only feeding between the hours of 8:00AM and 4:00PM.  Alternatively, some folks will adjust caloric density based on level of activity- during times of intense exercise calories go up, while no calories are offered during sedentary periods- this is a very responsive way of feeding at interval.

Finally, replacing a portion of a standard serving of kibble with fibrous raw vegetables such as green beans, or feeding a raw meat diet low in carbohydrate, are very simple methods of controlling calories.

Feeding your dog purposefully with their long-term health in mind, will offer both you and them a longer and more enjoyable life experience.
