The Science of Taste

Understanding how animals experience food helps us make better choices for the pets we love.

A few summers ago, we went on a wine tour in Wolfville with some friends. As we laughed and enjoyed the sunny day - I listened to them debate the flavours.

Someone mentioned citrus notes.

Someone else thought they tasted oak.

There was talk of balance, finish, and structure - the kind of conversation where people start using food words very seriously.

It made me think about how differently humans and pets experience food.

We tend to look for complexity.

Pets tend to look for clarity.

How Pets Experience Taste

Dogs have fewer taste buds than humans - roughly 1,700 compared to our 8,000 to 10,000.

But taste buds are only part of the story.

Dogs can detect the same basic taste categories we do, including sweet, salty, sour, bitter, and savoury (umami).

What really matters for dogs is protein detection.

Their tongues contain paired receptors called T1R1 & T1R3. When free amino acids such as glutamate bind to these receptors, the brain receives a simple signal:

Protein is present.

From an evolutionary perspective, protein means energy, muscle maintenance, and survival.

Dogs aren’t thinking about flavour notes the way we do.

They are responding to biological signals their bodies are naturally built to recognize.

Smell Is Where the Experience Happens

If humans experience food primarily through taste, pets experience food primarily through smell.

Dogs can have up to 300 million scent receptors, compared to about 6 million in humans. Their brains are highly specialised for processing aroma.

Many compounds that create savoury flavour also contribute to scent.

So eating becomes a process of confirmation:

Yes, this is meat. Yes, this is food worth paying attention to.

What About Cats?

The science of taste isn’t unique to dogs.

Cats are obligate carnivores, meaning their bodies are designed to rely heavily on meat.

Cats have even less taste buds than dogs Roughly 500 taste buds and they cannot taste sweetness - the gene responsible for sweet flavours is essentially inactive.

Like dogs, cats rely heavily on protein detection through savoury receptors that respond to amino acids such as glutamate.

Smell also plays a major role. If a food’s aroma doesn’t signal freshness or meat content, many cats will simply walk away.

Both dogs and cats tend to respond best to food that is protein-rich, biologically simple, and true to its source.

Why Freeze-Dried Treats Are Different

High-heat cooking can change protein structure and reduce delicate aromatic compounds.

Freeze-drying works at low temperatures by removing moisture without destroying natural chemistry.

This helps preserve:

• Protein structure

• Naturally occurring amino acids

• The original scent profile of the ingredient

  
  

The result is a treat that doesn’t try to imitate flavour. It simply preserves it.

Not “beef-flavoured.” Just beef.

Not “salmon-style.” Just salmon.

To us, the aroma may feel gentle and clean.

To pets, it’s meaningful and recognizable.

Simple Isn’t Small

Pets aren't interested in culinary complexity. They respond to certainty.

One ingredient means one dominant sensory signal.

No fillers trying to hide behind flavour. No artificial notes trying to compete.

In a pet’s world, simplicity isn’t minimalism. It’s focus.

We may have more taste buds, but animals are remarkably good at finding what matters most when it comes to food.

And when a treat preserves that natural signal - the protein, the aroma, the honesty of the ingredient - they tend to notice it immediately.

Probably faster than you can open the bag.

A Simple Philosophy

Pets don’t care about flavour notes or culinary trends. They care about whether food smells right.

Whether it feels familiar.

Whether it’s worth paying attention to.

There’s something reassuring about giving your pet food that doesn’t hide behind complexity - just real ingredients, carefully preserved.

And if your dog or cat is anything like most pets, they probably won’t spend much time thinking about the science of it.

They’ll just be waiting by the kitchen.

Listening for the sound of the bag.

At Sam & Paisley, we believe the best treats don’t try to be complicated. They simply start with real, quality ingredients, preserved carefully for the animals who enjoy them.
