Our dogs’ behavior is always changing. They find new interests and interact with the environment in ways we’ve never seen before. That is a sign of a behaviorally healthy dog.
New phobias or aggressive dog behavior are not so healthy. Those kinds of behavior changes can crop up throughout our dogs’ lives for various reasons.
Puppyhood and Adolescence (the first two years)
These are developmental changes. New fears and first-time aggressive behavior are fairly common. Common does not mean they are acceptable or that we should ignore them. On the contrary. We need to intervene and help our dogs at the first sign of fear or aggression. Causes include socialization deficits (our dog’s lack of positive experiences), emotional trauma (including before birth), and genetic predisposition (not always permanent). Early positive reinforcement training can turn this kind of unwanted behavior around when our dog is still young. It’s also a great way to prevent fear and aggression problems.
Adulthood
If our dog begins behaving fearfully or aggressively as an adult, we still need to take action. This is especially true for dogs who have otherwise been joyful and pro-social for the first several years of their life. A sudden change in behavior in our adult dog is a red flag. Our first step is to take the dog to the vet to rule out pain (that’s a big one) or other medical causation. Be thorough. Ask lots of questions. Make note of environmental changes, like a move to a new home, a new partner or roommate, or a baby growing into toddlerhood. Those can all affect our dogs’ behavior. We still recommend positive reinforcement training for adult dogs.
Senior Dogs
When a senior dog’s behavior changes, we look for the same causes we’d consider in a younger adult dog. In addition, we can ask our vet to begin regular senior blood work and test for any cognitive decline. Yes, old dogs benefit from positive reinforcement behavior change training. Age does not impede this. But, a late-in-life development of fear and aggression almost always involves vet care as well.
It’s Not All Bad
Behavior is always changing, from birth all the way until our dogs’ last days. Most of the changes we see are benign, delightful, even cute. Many dogs learn to play in new ways, make new friends (human and dog), discover new toys, or learn to enjoy new favorite sleeping spots (mine loves to sunbathe). Cherish these moments. Remember them. They will become part of the stories you tell long after your sweet dog has passed.
I’ll help with the unwanted behavior. The good behavior changes: those are yours to keep in the most treasured parts of your memory.
