Overall, the researchers found that the dogs' attentiveness and ability to solve problems changed a lot during life, improving up until about 6 years of age and then remaining stable.
Puppies typically develop the emotional maturity and temperament of an adult dog between twelve and eighteen months of age, although they may continue to occasionally exhibit puppy behavior like chewing and nipping until they're about two years old.
It does appear that as dogs age that they become calmer but in fact, your dogs energy level is set at a certain age and will not get less, what will happen though, is that your dog will learn when to be excited and when not to be.
But one new study found that dogs actually experience a personality shift around their third birthday, which might be the reason they stop seeking novelty as they hit middle age. (Yes, it's true, dogs can hit that “middle age” milestone as early as two, per Science magazine.)
Like humans, dogs go through a rebellious “teenager” phase (around 5 months to 18 months). During this time, they'll often test their owners, seeing what they can get away with. Being firm and consistent with your training will help establish boundaries.
Approximately 35% of owners and trainers voted 8-9 months as the toughest age citing new challenging behaviors associated with their puppy's now larger size such as pulling on the leash or counter-surfing. Interested in adding a new puppy to your family?
Most puppies start to calm down as they approach their maturity age, which is usually around 12 months, but for larger breeds it can be more likely to occur between 18 months and 2 years.
In most cases, dominant behavior occurs when a dog has reached maturity, somewhere between one and three years old. However, it's not uncommon for dominant behavior to occur in older dogs or puppies.
12–18 Months
Somewhere during this period, your dog will reach emotional maturity; sooner, with small breeds, and later for large dogs.
Researchers at Michigan State University have discovered that dogs often take on the same personality traits as their owner. The study revealed that dogs are like humans in that they have personalities that are shaped over time.
When dogs engage in high-energy activities, certain chemicals are released in their body that prepare the dog for fight or flight. These chemicals include cortisol, adrenaline, and norepinephrine. With these hormones coursing through their body, it's very hard for the dog to settle down and relax.
Behavioral and Mental Signs of Aging in Dogs
Changes in behavior can signal an underlying physical problem or may be a normal sign of aging. For example, if your sweet dog has suddenly turned grumpy, they may be in pain caused by arthritis or be experiencing some other physical discomfort.
Ryan Seacrest shared if you want to train your dog, they are most teachable at age 6. A recent study says the sweet spot for dog obedience is not the puppy stage, but actually 6 years old. Why? They've outgrown the excitable puppy stage, but 6 is before they are too set in their ways.
Growth stage: By one year
By the time they're one year old, dogs should be making progress in learning of all the polite behaviors they will need for the rest of their lives.
If your dog is between 5 and 18 months of age, he is just experiencing the ups and downs of the teenage years. His bad behavior probably appears as a result of this rebellious phase and his need to test your boundaries. Dogs tend to bury their pain, but their behavior will sooner or later reveal hidden emotions.
While most people associate training with puppies, the reality is that dogs can learn at any age. Adult dogs are often easier to train than young puppies because they have more self-control. It's also important to keep training your dog as it matures.
If you're anything like us, you'll probably continue referring to your dog as a puppy until they're old and grey!

At what age is it too late to train a dog? Of course, you know the answer by now: It is not ever too late. Training works at any point in a dog's life. Whether you start the day you bring your puppy home, or when your 10 year old dog finally needs to stop his leash pulling habit.
Most dogs assume a neutral or submissive role toward people, but some dogs will challenge their owners for dominance. A dominant dog may stare, bark, growl, snap, or even bite when you give him a command or ask him to give up a toy, treat, or resting place.
“If your dog whines, barks, paws at you, or nudges you to get affection, this means that they don't respect your personal space and they won't listen to you in other areas of training and leadership.” This one may be tricky for dog owners.
The presence of hormone named oxytocin releases excitement in the dogs to greet their owners when they meet their owners, Socializing traits in dogs are similar to humans which make them happy to be in the company of their owners. So they are excited and happy when they are around their owners.
