How Your Pet Learns — It Matters More Than You Think

Have you ever wondered how your pet learns — not just during training, but in everyday life? As a veterinary behaviourist, I recognise that learning is happening continually. When a dozing dog hears the fridge door and races to the kitchen, or when a cat starts hiding at the sight of the vacuum cleaner, they’re showing how powerful learning really is.

In this blog, we’ll explore how animals learn through experience, how we sometimes teach without meaning to, and why understanding these processes can help us support our pets.

What is animal learning, and why does it matter?

When we talk about “learning” in animals, we’re really talking about how they adapt and survive in their world.

Every day, pets notice the things happening around them — the stimuli in their world. These might be sounds, sights, smells, people, other animals, or even things that cause pain. Their senses detect them, and their brains decide how to respond to that information. Learning helps them stay safe and understand what leads to positive outcomes and positive feelings (and what doesn’t).

It starts before they’re even born and continues throughout their whole lives.

Pets learn in a few different ways:

• through repeated exposure to the same stimulus,
• by forming associations between stimuli and events,
• and by observing others.

All of these shape how they behave.

Non-associative learning — getting used to things (or not)

This type of learning is all about repeated exposure to the same thing.

There are two main patterns:

Habituation — “I’ve noticed this before, it’s fine, I’ll ignore it.”

A harmless stimulus becomes less interesting over time. Think of a dog who pricks up their ears the first few times the washing machine spins, then eventually stops reacting — it turns into something they simply tune out.

Sensitisation — “This keeps happening, and it’s getting to me.”

The more the stimulus happens, the bigger the reaction. A cat might barely notice the kettle clicking off at first, but hearing it repeatedly can start to bother or unsettle them.

Animals can habituate or become sensitised to stimuli at any age, and it is especially important to consider this when choosing a new puppy or kitten.

A youngster raised in a busy, family household tends to take everyday life in stride. Their early experiences — along with their individual temperament and even their mother’s stress levels during pregnancy — help shape how confidently they handle new situations.

A puppy or kitten raised in a barn or puppy farm may not have had this exposure. For them, vacuum cleaners, televisions, or children playing can feel overwhelming. Instead of getting used to these things, they may become more sensitive to them over time.

Associative learning — “when X happens, Y follows”

This is where animals learn that one thing predicts another, or that their own behaviour leads to certain outcomes. It includes classical conditioning and operant conditioning.

Classical conditioning — automatic emotional learning

This is the type of learning Pavlov described. Animals learn that one event predicts another. Classical conditioning is all about reflexes and emotions — the animal isn’t choosing to feel excited or anxious; the association creates that response.

A familiar example in training is teaching a marker word or clicker. You say “yes” or click, then immediately give a treat. After enough repetitions, the marker predicts the reward, and your pet feels a spark of positive anticipation.

You’ll see this outside of training too. If you pair a collar or harness with treats, your pet can learn that the collar predicts something good. What could have been stressful becomes a positive experience.

Operant conditioning — learning through consequences

This is voluntary learning. The animal tries a behaviour; something happens—the consequence —and they decide whether to do it again.

Consequences fall into two groups:

• Reinforcers — things that make a behaviour more likely (or rewards)
• Punishers — things that make a behaviour less likely

In force-free training, we focus on adding rewards that matter to the individual animal — food, toys, praise, sniffing, play — to encourage the behaviours we want.

Punishers include shouting, stern voices, or physical corrections such as choke chains, prong collars, or shock collars. These methods can create fear, pain, and confusion, and they damage the trust between a pet and their people. That’s why I never use them and don’t recommend them.

Learning is happening continuously – not just during training

Learning happens in everyday life and is shaped by emotions and results as much as by practice.

A loud bang, like fireworks outside, can trigger a reflex startle or fear response— the dog’s heart races, muscles tense, and they may try to hide. That emotional reaction becomes part of the learning process, teaching them that fireworks are something frightening.

On the other hand, the smell of roast chicken on the kitchen worktop causes excitement and anticipation. If the dog manages to jump up and grab some, the pleasure of eating it reinforces the behaviour. In other words, the reward makes jumping up more likely to happen again the next time they smell or see food on the counter.

What feels rewarding or punishing depends on how the individual animal experiences it in that moment. And it’s not always under our control — everyday sights, sounds, and stimuli can shape behaviour through the emotions they trigger.
