When dog trainer and PETBOOK author Katharina Marioth gets a call, it’s rarely just about a “small training request.” Often, the initial question “Can you stop my dog from doing that?” has more behind it than one might initially think. There’s a good reason why dog trainers sometimes decline such requests.
Why Dog Trainers Sometimes Decline Requests
There’s a call every dog trainer knows if they’ve been in the profession for more than two years. It usually comes on a Monday, often after an apparently intense weekend. The voice on the phone sounds either desperate, slightly irritated, or suspiciously excited—and before you can even say “Hello,” the sentence comes: “I need someone to teach my dog not to do that anymore.”
What “that” is becomes clear in the next ten minutes. Sometimes it’s barking, sometimes chasing, sometimes tearing up cushions. And sometimes—these are the calls you think about in the evening—it’s something that makes you take a deep breath and very politely ask if you understood correctly.
Dog training is a rewarding profession. It’s also a profession where you learn to politely say “No.” More often than you might have expected when starting out.
1. “Can You Stop Him from Barking Completely?”
Let’s start with the classics. Requests that come so regularly that you eventually develop a sort of internal bingo card. At the top: the desire for a silent dog. Not a quieter dog. A mute dog. Completely. Forever.
Barking isn’t a bad habit. Barking is communication. It’s what dogs do when they’re excited, want to alert, want to play, are scared, or simply: exist. Teaching a dog to “stop barking completely” is akin to teaching a two-year-old never to cry again.
What can be trained: when, how long, in response to what. What can’t be trained—and shouldn’t be—is the silencing of a healthy, communicative being. Any trainer who promises that is either lying or using methods you’d rather not look at too closely. Spray collars, prong collars, electronic devices—the German Animal Welfare Federation clearly opposes such tools in its position paper, not for sentimental reasons, but because they demonstrably cause fear and stress without solving the actual problem.
2. “He Should Learn He’s the Smallest in the Pack”
The ultimate classic. Sometimes it comes disguised as a question, sometimes as a statement. And sometimes accompanied by a YouTube link to a show filmed fifteen years ago that has stubbornly circulated online ever since.
The pack leader theory—the idea that dogs constantly try to dominate humans and therefore need to be shown “who’s the boss”—has been scientifically outdated for decades. It was based on observations of captive wolves from the 1940s, which were later even retracted by the original author. Applied to dogs, it was always a misinterpretation. Its persistence, like gum under a restaurant table, says more about human projections than about dog behavior.
Dogs need guidance, reliability, and clear structures. That’s true. But it has nothing to do with “subjugating” them. A trainer who shows a dog dominance by pinning it on its back ignores everything behavioral research has discovered in the past thirty years. And risks—incidentally—being bitten.
3. “He Just Needs to Learn to Endure It”
This request comes in variations. The dog is afraid of thunderstorms—he needs to learn that nothing will happen to him. The dog is tense around other dogs—he just needs to go to dog school more often. Also, the dog trembles at the vet—he should get used to it.
It sounds reasonable—but it’s not.
Fear isn’t a character flaw that can be trained away through confrontation. Fear is a neurobiological state, and a dog that is afraid and forced to endure the fear-inducing situation doesn’t learn that the situation is harmless. He learns that he has no control. This is called learned helplessness—and it’s the opposite of what you want to achieve. A dog that has stopped trembling because he has given up looks relaxed at first glance. He is not.
Good training for fear means: desensitization in small steps, at the level the animal can currently handle. Not: throwing them in and hoping it works. A trainer who offers this takes on a task that harms the animal—and should decline it.
4. “Just Do It in an Intensive Week”
This request comes more often than you think, and it has something endearing about it. The idea that a dog—similar to a driver’s license—can be “fully trained” in a compact unit and then be done. Forever. Ready to use.
Training doesn’t work like a software update. Behavior that is meant to be permanently stable requires repetition, context, and above all: a person who consistently continues what has been learned in everyday life. An intensive week where the trainer works with the dog while the owner waits at home can be a good start. But it’s no substitute for what comes afterward.
Dog trainers, when things go well, don’t train the dog. They train the person. Anyone who doesn’t want that—who wants the problem to just be “fixed” without having to change anything themselves—will be unhappy with any trainer. Because the dog takes what has been learned home. And encounters the everyday life that produced the behavior in the first place.

5. “He Should Learn to Stay Alone—Starting Tomorrow, I Have to Go Back to the Office Next Week”
This request deserves its own paragraph because it contains a mix of genuine need and breathtaking optimism that a trainer somehow has to respect. The dog has had severe separation anxiety for two years. Next week, the person has to return from home office to the office. Will it work by then?
No. It won’t work by then.
Separation anxiety is one of the most complex behavioral changes in dog training. In many cases, it also has medical dimensions—the connection with thyroid function, pain issues, or chronic stress is well documented. Solving it in seven days is about as realistic as saying you want to speak fluent Japanese by the day after tomorrow because you have a trip planned.
What can be done: be honest. Find a good transitional solution for the dog. And work with the dog in parallel—seriously, patiently, realistically.
Why It’s Okay for Dog Trainers to Decline Requests
When a trainer says “No,” it’s not a sign of arrogance. It’s usually a sign that he or she is focused on the dog—and not just the owner’s wishes. That’s sometimes uncomfortable. Sometimes the customer then goes to the next provider who says “Yes.” And sometimes they come back three months later, and then you start.
Good animal welfare doesn’t start in the shelter. It starts the moment someone says: “That’s not what your dog needs. Let’s see what he really needs.”
That sounds less like a service. But it’s the better work.
