Older dog and puppy behavior can be quite difference, depending on the breed and how old a dog is. Though extreme changes of behavior over a very short amount of time may be a sign of a medical condition, a gradual mellowness in temperament is to be expected at a certain point in a dog's life.
Characteristics of a Puppy
Puppies go through developmental stages. A puppy typically is weaned from his mother at 8 weeks, and completes his adolescence at 18 months. During this time, a puppy is:
- active
- gaining confidence
- exploring the world
- establishing relationships and behaviors
- learning roles and rules through play and training
Puppies often have have:
- short attention spans
- high energy
- the need to find their place in dominance hierarchies
- a high level of adaptability
- a need to urinate every 2 to 3 hours
- fear if not confined in a safe space if left alone
When a Dog Has Become an Adult
Whereas puppies need to explore, adult dogs appreciate predictability.
Adult dogs usually:
- can be left alone in a house for 9 to 10 hours without urinating
- exhibit a calm disposition toward other dogs and people
- settle into a learned role and relationship style
- can learn new behaviors and games
- respond to positive attention
These may not apply to all breeds and individual dogs but, compared to the dog as a puppy (and minus any traumatic experiences or unusual aggression problems), they are much more likely in the adult dog.
Senior Dogs Are Less Energetic
As a dog becomes a senior, he will:
- be less active
- sleep more
- enjoy, and be more content with, mellow playing, walking and interacting
- tire faster
As a dog ages, his behavior matures and he becomes a consistent and predictable companion.
