When we think about a dog with a behavior problem, we usually think about training.
A dog lunges at other dogs? Work on reactivity or aggression.
A dog can’t settle? Teach a place command.
A dog struggles to focus? Practice watch me.
And training absolutely matters.
But there’s another question worth asking:
How does that dog feel inside their own body?
Because behavior doesn’t happen separately from the body. The brain depends on nutrients. Hormones and neurotransmitters influence mood and stress responses. Physical discomfort can affect tolerance. Hunger can affect behavior. Energy availability can affect how an animal functions.
So sometimes, before asking, “How do I make my dog behave differently?” it may be worth asking:
“Am I giving their body what it needs to feel and function its best?”
I Learned This With Wellingtin
Wellingtin was leash reactive to other dogs. Which manifested as him at the end of his leash loosing his mind barking. Not a pretty picture for a Cavalier King Charles Spaniel. And difficult to manage because going on walks and having adventures was a favorite pastime before.
We did private lessons. We trained. We practiced. I learned how to better communicate with him, how to help him navigate the world, and how to control my response to seeing other dogs.
Those things mattered.
But looking back, the biggest change didn't begin with a new training techniques.
It began with his bowl.
When I switched Wellingtin to raw food, he started to change.
His reactivity didn't magically disappear because I put raw meat in a bowl. We still had work to do.
But suddenly, that work seemed to work better. I was seeing marked progress after every training session.
He could focus better. It was easier to get and keep his attention. His reactions slowly softened. And over time, the reactive dog I had known, was able to happily interact with other dogs. Sniffing them, laying down in their presence, going for walks with them. It made life so much more enjoyable for both of us! And we could go for walk & adventures again without fear of other dogs.
The training was super important, but changing his diet changed the foundation we were training on.
That experience made me start thinking about behavior differently.
You Can't Separate the Brain From the Body
We often talk about behavior as though it exists entirely between a dog's ears.
But the brain is an organ, too.
It requires amino acids, fatty acids, vitamins, minerals and energy to function. Nutrients are involved in the production and regulation of neurotransmitters and hormones that influence things like cognition, mood and stress response.
Researchers studying canine nutrition and behavior have explored relationships involving amino acids such as tryptophan and tyrosine, fatty acids such as DHA, feeding motivation and other dietary factors.
The science isn't at a point where we can say, "Feed X and your dog's reactivity will disappear."
Behavior is far too complex for that.
But we can say that nutrition and behavior aren't two completely separate subjects.
And intuitively, that shouldn't be surprising.
Think About How Food Makes You Feel
Imagine two different weeks.
For the first week, nearly everything you eat comes from a fast-food drive-through.
Burger. Fries. Soda.
Repeat.
You could certainly consume enough calories to survive.
But how would you feel by day seven?
Now imagine a week of fresh, minimally processed foods: quality proteins, nourishing fats and whole-food ingredients.
You might notice a difference in your energy, concentration, digestion, sleep, mood or simply how you feel moving through your day.
Now consider this:
Many dogs eat essentially the exact same food, at every meal, every day, for years.
If food can influence how we feel and function, why wouldn't we at least consider nutrition when looking at the whole dog?
The Energy Roller Coaster
Carbohydrates aren't inherently poisonous, and some dogs are capable of digesting starch fairly well. But unlike protein and fat, dietary carbohydrate is not considered an essential nutrient for dogs.
And dry kibble generally requires starch as part of its manufacturing process.
That creates an interesting question when we're talking about behavior:
What happens when we fuel an animal primarily one way versus another?
After a carbohydrate-containing meal, glucose enters the bloodstream and insulin helps move that glucose where it needs to go. The body is very good at regulating this process in healthy animals.
But meal composition can affect the metabolic response to food. Which can cause blood sugar spikes & crashes.
For humans, we know the feelings associated with blood sugar spikes and crashes all too well: hungry again, tired, distracted, thirsty, irritable, foggy, struggling to concentrate.
That doesn't mean we should diagnose a reactive dog with a "sugar crash."
It does mean that stable energy and appropriate nutrition deserve a place in the conversation about focus, resilience and behavior.
Training asks a dog's brain to do a lot.
Notice the trigger.
Think instead of react.
Hear the handler.
Make a different choice.
Recover.
Try again.
Why wouldn't we want to support that brain nutritionally, too?
Food Is More Than Calories
There's another important difference between fresh food and heavily processed food.
A whole-food ingredient isn't simply a delivery system for calories.
Meat, organs and other animal-sourced foods naturally provide amino acids, fatty acids, vitamins, minerals and other compounds the body can use.
Those nutrients matter to the nervous system as well as the rest of the body.
Nutrition research has specifically looked at the roles of amino acids and fatty acids in canine cognition, mood and behavior.
That doesn't mean "more protein fixes aggression" — in fact, research into individual nutrients and behavior is considerably more complicated than that. But it does means the raw materials we give the body to use matter.
You cannot build a well-functioning brain without adequately nourishing it.
And Then There's Processing
Kibble is designed to be shelf-stable and convenient. Raw food is fundamentally different: fresh animal ingredients with minimal processing and naturally high moisture.
Processing changes food, and kibble manufacturers need to formulate foods with synthetic vitamins and minerals to ensure the finished product meets established nutritional requirements. These synthetic nutrients are often more difficult for a dog's body to recognize & use. Which takes more energy for digestion & leaves less for training.
There's also another issue worth understanding: contamination. Many kibbles are contaminated with molds that produce compounds called mycotoxins. Aflatoxin is one example, and contaminated pet food has caused documented illnesses and recalls. But the main issue is that these contaminates cause the body to use it's energy to work to move those toxins out. Again leaving less energy for focus & training.
At My Pet Carnivore, that's one reason we're so interested in keeping food simple.
Real animal ingredients.
Minimal processing.
No unnecessary fillers.
Food that still looks like food.
Sometimes "Bad Behavior" Starts With Feeling Bad
Think about yourself on a day when you're exhausted.
Or hungry.
Or your stomach hurts.
Or you have a pounding headache.
How much patience do you have?
How well do you concentrate?
Is your anxiety heightened?
How resilient are you when something frustrating happens?
Probably less than when you're rested, nourished and feeling great.
A dog dealing with physical discomfort, digestive upset, persistent hunger, poor sleep or inadequate nutrition may simply have less capacity available when something stressful happens.
If your dog's threshold is already here:
──────────── trigger
It may not take much to push them over it.
But improving the things we can control — nutrition, sleep, physical health, appropriate exercise, enrichment, training and environment — can help give that dog the best foundation possible.
Raw Food Isn't Obedience School in a Bowl
I would never tell someone:
"Your dog is reactive? Just feed raw."
That wasn't Wellingtin's story.
He needed training.
I needed education.
We needed practice.
But when I changed his nutrition, it felt like all of that work was working better & faster.
Instead of thinking about nutrition or training, I started thinking about nutrition and training.
Feed the body.
Support the brain.
Teach the skills.
Work with the dog in front of you.
Start With the Bowl
Behavior problems can have many causes: genetics, early experiences, fear, pain, environment, learning history, unmet needs and medical conditions among them.
Food is not the explanation for every behavior problem. But it shouldn't be automatically excluded from the conversation, either.
If we're asking a dog's brain to learn, regulate, concentrate and recover from stress, it makes sense to consider what we're giving that brain — and the rest of the body — to work with.
That's what Wellingtin taught me.
The private lessons mattered.
The training mattered.
The practice mattered.
But the biggest changes began when I changed what was in his bowl.
If your pup has been challenged with a behavioral issue and your are doing the training, but results seem slow. Maybe it's time to give raw feeding a try!
