Pet Behavior Myths That Many Owners Still Believe

Research by animal cognition scientist Alexandra Horowitz found that the 'guilty look' appeared whether or not the dog had actually misbehaved — it was reliably triggered by an owner's scolding tone, not the dog's awareness of wrongdoing. Dogs live primarily in the present moment and lack the capacity to connect a past action with a current consequence the way humans can. Responding with anger to this expression is therefore unlikely to teach anything useful and may increase the dog's general anxiety around you.

The original wolf-hierarchy studies that inspired dominance-based dog training were later revised by the same researcher, David Mech, who clarified that wild wolf packs are family units, not rigid dominance hierarchies. Domestic dogs are not wolves, and the leap from wolf studies to pet dog training was always a stretch. Most problem behaviors stem from fear, insufficient guidance, or unmet needs — not a bid for social dominance. For a deeper look at how this theory continues to mislead owners, see our article on dominance theory myths.

A low, loose wag typically signals a relaxed or submissive dog. A stiff, high wag with a rigid body can indicate alertness or agitation. Research has even suggested that wags biased to the right side of a dog's body tend to reflect positive states, while left-biased wags may indicate negative arousal. Reading a wag in isolation — without the rest of the dog's body — is the mistake. Understanding the full picture of canine communication is essential for safe interactions. Our guide on canine body language goes into much more detail.

Studies from researchers including Kristyn Vitale at Oregon State University have shown that cats can form secure and insecure attachment styles with their owners — much like dogs and young children do. Behavioral issues like over-grooming, aggression, or destructive scratching are often signs of boredom, stress, or inadequate play opportunities rather than an inherent personality flaw. If you're still getting to know feline behavior, our introduction to cat behavior covers the fundamentals clearly.

The American Veterinary Society of Animal Behavior and numerous peer-reviewed studies support reward-based training as both more effective and less harmful to the human-animal bond. Punishment can suppress a behavior in the moment without addressing why it's occurring — and it can make a dog associate the owner with an unpleasant or frightening experience. Animals trained primarily with fear often become anxious, shut down, or redirect their stress into other problematic behaviors. For an honest breakdown of the documented trade-offs, read what punishment-based training actually does to animals.

Growling is one of the clearest signals a dog can offer that it is uncomfortable. When owners punish growling, the dog doesn't become less uncomfortable — it simply loses a tool it used to express that discomfort. This is how dogs that seem to bite 'out of nowhere' develop: the warning signals were trained away. Understanding what's driving the growl — whether that's fear, resource guarding, or pain — is where effective intervention begins. Our article on resource guarding in dogs explains how to recognize and respond to these signals safely.
