Here’s the scenario: your pet recently began to do something really out of character. Maybe she started snapping at another household pet, or maybe he started to -gross!- eat his own poop. You know this calls for a professional’s input, but who can help? Should you bring in a pet trainer, or is this a case for a different kind of specialist known as an animal behaviorist? We’ll share the differences between the two pet pros so you can get the help you need.
Pet Trainers
Pet trainers are individuals who work to teach animals skills and change animal behaviors. These include actionable commands like “sit, stay, come” but also include situational behaviors – like teaching a dog not to jump on guests when they enter the home.
In addition to working with the dog, cat, horse, or other animal, trainers work with the pet owner to reinforce learnings. Trainers will provide direction to owners so that the skills can be practiced and perfected outside of the training environment. This “homework” helps teach owners to reinforce the learned behaviors, so it’s crucial that trainers are good communicators with humans, too!
Trainers can be self-taught, take animal behavior courses, or work with other trainers to learn their skill. What all good trainers have in common, though, are many hours of successful practice sessions with animal clients! Though there are a variety of training school offerings and certification courses, there is only one nationally recognized certification for dog trainers: the Certification Council for Professional Dog Trainers (CCPDT). To become certified, individuals must log a required amount of training hours, have letters of recommendation, and pass an evaluation on canine ethology (behavior), basic learning theory, and canine husbandry (a branch of agriculture that deals with breeding and raising domestic animals).
“A dog trainer helps lay a basic foundation for your pup and can handle basic issues. An Applied Animal Behavior Consultant (someone with a Master’s or PhD in Animal Behavior) is more specialized.” – Reddit User
How does an Animal Trainer work?
Animal trainers will typically meet with your pet one on one, or in small group settings with other pets. Some trainers will seclude pets from their owners, while others work with both trainer and owner together so owners can actively reinforce from the beginning. There are also trainers and facilities that give you the option to board your animal for an extended period of time. This fully immerses them in the training environment, which can be more efficient for behaviors like high energy or aggression.
To teach pets, trainers will use methods like desensitization (repeatedly exposing pets to certain high-stimulation situations, like coming in contact with a unfamiliar person, in order to change their response), positive reinforcement (like providing a treat when an animal correctly responds to a command), clicker training (using a small clicker or other noise-maker while giving a command, so that the animal learns to take action by sound), hand signals (using a hand signal while giving a command so that the animal learns to take action by visual signal), and other tactics.
When to seek a Trainer
Working with a trainer is a great solution to teach your pet new skills or to improve obedience. Situations in which you might find a pet trainer to be helpful include housebreaking your pet; teaching commands such as sit, stay, come, heel, down, etc.; eliciting certain responses to your actions, i.e. dropping their toy at the sound of your snap; learning to walk on a leash without resistance; teaching boundaries, i.e. keeping your pet in your backyard (or off of your favorite sofa!); or even socializing your pet to become more comfortable around other animals. You can book a certified dog trainer on Petworks.
Animal Behaviorists
Like pet trainers, animal behaviorists dedicate their livelihoods to understanding animal behavior. However, behaviorists typically focus on the psychological motivation behind an animal’s actions and take many rigorous courses in psychology, communication, and behavior.
Those studying animal behavior may take the path of zoologist or even become a college professor, but many go on to specialize in small domestic and companion animals. Behaviorists who are experts in companion animal behavior come in 3 different categories: Applied Animal Behaviorists, Certified Applied Animal Behaviorists (CAABs) and Associate Certified Applied Animal Behaviorists (ACAABs). All of the above holds a Master’s Degree in an animal behavior-related field, while CAABs hold a doctoral degree.
How does an Animal Behaviorist work?
Behaviorists heavily study behavior modification, so they know the effective techniques to produce changes in behavior. They also know what is considered “normal behavior,” and can effectively recognize when your pet is acting out of the ordinary. To do so, many behaviorists begin by observing your pet in their natural environment. They pick up on environmental cues to help determine what might be triggering your pet’s actions. They then may begin to work one on one with your pet, emulating what they observed to try to mimic, and ultimately correct, the undesired actions. Like trainers, behaviorists also have experience with counseling and aiding people so they can teach how to understand and work with your pet. Most CAABs work through veterinary referrals, and can work with veterinarians to select behavioral medications should your pet require them.

FAQs: Dog Trainer vs. Dog Behaviorist
What is the main difference between a dog trainer and a dog behaviorist?
A dog trainer focuses on teaching specific skills and obedience commands, often using positive reinforcement. A dog behaviorist studies and modifies underlying behavioral issues like aggression, anxiety, or fear, often with advanced education in animal behavior.
Do I need a dog behaviorist if my dog just doesn’t listen?
Not usually. For basic obedience, manners, or tricks, a professional dog trainer is sufficient. A behaviorist is recommended for complex behavioral problems that may have psychological or medical components.
What qualifications do dog behaviorists have?
Many behaviorists hold advanced degrees in animal behavior, psychology, or veterinary science. They may also have certifications such as Certified Applied Animal Behaviorist (CAAB) or equivalent credentials.
Can a dog trainer handle aggression issues?
Some trainers are experienced in mild aggression cases, but serious aggression, fear-based behavior, or anxiety typically requires a behaviorist’s expertise.
How do I know whether to hire a pet trainer or a pet behaviorist?
-
Trainer: Obedience, tricks, potty training, basic manners.
-
Behaviorist: Aggression, phobias, separation anxiety, compulsive behaviors, or other complex issues.
Can a dog behaviorist also train dogs?
Yes, many behaviorists incorporate training techniques, but their focus is on addressing root causes of behavioral problems rather than teaching basic commands.
How long does it take to see results?
-
Trainer: Often weeks to months for obedience training.
-
Behaviorist: May take months to fully address complex behavioral issues, as it involves changing underlying patterns and often collaborating with veterinarians.
Are behaviorists more expensive than trainers?
Typically, yes. Behaviorists’ sessions may cost more due to their specialized knowledge, education, and the complexity of cases they handle.
Can both work together?
Absolutely. Many pet owners benefit from a combination: a trainer for daily obedience and a behaviorist for deeper behavioral issues.
Where can I find certified behaviorists and trainers?
Look for professionals through:
-
Dog Trainers: Association of Professional Dog Trainers (APDT), International Association of Canine Professionals (IACP), and Petworks.
-
Behaviorists: American College of Veterinary Behaviorists (ACVB), Certified Applied Animal Behaviorists (CAAB), and Petworks.
When to seek an Animal Behaviorist
If your pet’s actions are beyond basic obedience, it may be necessary to bring in a behaviorist. Some scenarios include handling issues, like extreme resistance to leashed walks; resource guarding, in which your pet aggressively “protects” food, toys, or even it’s owner!; excessive barking or meowing, sometimes without trigger; certain fears, like inanimate objects, sounds or actions; separation anxiety; serious behavior problems that put your pet, people or other animals at risk; or the aforementioned -gross!- eating poop. The best way to determine which professional you need for your pet is to connect with the professionals themselves! You can find an animal behaviorist on Petworks.
