Is it true you can’t teach an old dog new tricks? The truth plus 3 common pet training myths debunked

Last updated: March 8, 2026

We’ve all heard the phrase—maybe from a friend who gave up on training their senior dog, or a family member who swears puppies are the only ones worth teaching. But what does science actually say about this age-old myth?

The truth about old dogs and new tricks

A 2017 study from the University of Vienna tested 145 dogs (ages 1 to 14) on learning new commands like “touch” (nose to hand) and “spin.” The results? 90% of older dogs mastered at least one new trick within 10 short sessions. They took a bit longer than puppies—about 20% more time on average—but the difference wasn’t ability. It was patience: adult dogs need shorter, more frequent sessions to stay focused, whereas puppies can handle longer play-based training.

3 common pet training myths debunked

Myth 1: Punishment is the fastest way to stop bad behavior

Scolding your dog for chewing shoes or tapping a cat’s nose for scratching the couch might seem like a quick fix, but it’s counterproductive. A 2020 study in the Journal of Veterinary Behavior found that punishment increases anxiety in pets, leading to more unwanted behaviors (like hiding or aggression). Positive reinforcement—rewarding good behavior with treats, praise, or play—works way better. For example, if your dog sits instead of jumping on a guest, give them a treat immediately. They’ll associate sitting with a reward and repeat it next time.

Myth 2: Cats can’t be trained at all

Cats have a reputation for being independent, but that doesn’t mean they’re unteachable. Clicker training (using a small device that makes a clicking sound to mark good behavior) is super effective for cats. One cat owner I know taught their 5-year-old tabby to high-five and fetch a small toy using clicker training and tuna treats. The key? Use rewards your cat actually cares about—like their favorite snack or a laser pointer play session—instead of generic treats.

Myth 3: Puppies are always better learners than adult dogs

Puppies do have more neuroplasticity (flexible brains) than adult dogs, but adults have an advantage: better impulse control and longer attention spans. For example, an adult dog might pick up “stay” faster than a puppy because they don’t get distracted by every passing squirrel. The table below breaks down the key differences:

AspectPuppies (0-1 year)Adult Dogs (1+ years)
Learning Speed (Simple Commands)Faster (neuroplasticity)Slower but more consistent
Attention Span5-10 minutes per session15-20 minutes per session
Impulse ControlLow (easily distracted)High (focuses on tasks better)
Best Training MethodsShort, playful sessions with frequent rewardsStructured sessions with clear cues

Final thoughts: Training is for every pet

Whether you have a 10-year-old dog or a 3-year-old cat, training isn’t just about tricks—it’s about building trust and communication. The next time someone says you can’t teach an old dog new tricks, tell them about the Vienna study. And remember: patience and positive reinforcement go a long way, no matter how old your furry friend is.
