Stage 5: Adolescence (6 – 18 months) This can be the most difficult time during a puppy's development – adolescence. Your cute little puppy is becoming a teenager and will start producing hormones which may result in changes in behaviour.
Just when you may feel like you have hit your stride, the next big “difficult period” shows up! Many owners are totally blindsided by this next phase. It can vary a bit based on each dog, but your puppy likely will hit “adolescence” around 7-10 months, with 8-9 months being the peak described by most owners.
The adolescent period typically begins around six months of age, and will be over when a dog reaches physical maturity around two to three years old. The most pronounced behavioral issues will be noticed between six to 12 months old.
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.
6 Months - 1 Year Old
Your puppy should know all of their basic commands and have a solid foundation of potty training, crate training, and socialization. From this point on, you will continue to work with your puppy to reinforce what they have already learned!
The age of onset of dominance-related aggression is most commonly thought to be at social maturity around two years of age. However, it has been described in very young dogs (i.e. five months) and can also occur in older dogs.
Generally, puppies start to calm down when they reach emotional maturity — around 1 year old.
The Root of the Behavior
Canines who are aging are likely to grow more affectionate to their human companion as their reliance on them grows.
Changes in Socialization Patterns. Older dogs may become more or less social as they age. Some dogs become more affectionate and clingy, while others become more aloof and independent.
It's never too late to start dog training
In fact - as your dog ages it's important for his or her physical and mental health that they have good manners.
The Labrador Retriever earned the crown as the “naughtiest” breed. Traditionally, people know this popular dog for its friendly and outgoing nature. Yet, it seems that the breed's strength and energetic spirit could sometimes steer them into less desirable behaviors.
This adolescent stage of a dog's life is most commonly referred to as 'the terribles' or 'the terrible twos' and believe me, it is aptly named. In the simplest terms, the terribles is a stage of a dog's life in which they begin to challenge every rule, boundary, and limitation placed upon them previously.
"Dogs get less active with age, and that should give hope to the people who have puppies that are too active," Houpt said. "And while they become less oriented to problem-solving and novelty-seeking as they get older, they remain obedient and social, which is probably the most important thing for owners."
Not all dogs are affectionate, but if your dog once was cuddly and suddenly isn't, consider this a sign that something could be wrong. Any major changes in your dog's behavior or activities may warrant a trip to the vet to make sure there are no other issues, such as an illness or injury.
According to several behavioral measures, Coren says dogs' mental abilities are close to a human child age 2 to 2.5 years. The intelligence of various types of dogs does differ and the dog's breed determines some of these differences, Coren says.
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.
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.
By about two years of age, many dogs have reached the full extent of whatever aggression they have in them, and there may be a dogfight or biting incident around this time.
Breaking Eye Contact
In the wild, alphas put betas and omegas in their place with a decisive stare. If your dog breaks eye contact with you first, this is a dramatic sign of them viewing you as the alpha. It also demonstrates that you can discipline your dog with nothing more than a look.
Starting around 12 weeks, your puppy is less fearful and is becoming more curious and independent. He has a lot to figure out, including his place in the family pecking order. Personality traits, like dominance and submissiveness emerge, as he learns more social skills.
One to three year-old pups can be very energetic, hardly staying still for a single minute. As they age, however, they will begin to take longer and more frequent breaks between spurts. Most dogs will lose that seemingly abundant energy as they pass the three-to-four-year mark.
Health issues that can change your dog's behavior include arthritis, hip dysplasia, luxating patellas, sore teeth, thyroid problems, epilepsy/seizures, ear infections, digestive issues, skin or environmental allergies, yeast infections, hearing loss, eyesight loss, and cancer.
Having two dogs can feel like a lot of work sometimes, but the pros definitely outweigh the cons. From easier training to better mental and emotional health (for you and your dogs!), to saving the lives of animals, there are so many solid reasons to adopt a second dog today.
