Puppy Adolescence

Dog Life Stages: Puppy Adolescence Is Only a Phase

What to expect when your perfect puppy hits that unruly stage.

Dog adolescence, like the teenage years in people, is only a temporary phase. It brings about challenging behavioral changes that are reminiscent of human teenage years, but it catches many people off guard because they are not expecting it. I regularly have clients ask me, “Why didn’t anybody warn me?” It’s a fair question.

The answer is that most people don’t think much about the effect of age on dogs’ behavior. Sure, there are a few exceptions: Most people realize that puppies can’t control their bladders as long as adult dogs (even if house-training is progressing well and the pup seems to grasp the basic idea that the bathroom is outside). It’s also generally accepted that dogs in their golden years tire more easily (so that strenuous, three-hour hike should be reconsidered).

There are many dog life stages in between the times that dogs are very young and very old, and dogs’ behavior is influenced by their age a lot. The influence of age on behavior is not often taken into account, and that makes adolescence a surprise to many people. It’s only a phase, and that’s worth remembering when you find yourself dealing with the inevitable misunderstandings and frustrations of life with an adolescent dog. Forgetting this stage is only a temporary phase will be counterproductive to developing and enjoying a close relationship. In fact, relationships between people and dogs can be tested during adolescence, and it’s no coincidence that dogs are the most vulnerable to being surrendered to shelters and rescues at this stage.

What are the life stages of a dog?

The dog lifespan encompasses a number of dog life stages. For the first six to eight months of life, they are puppies. Then from six to eight months until about the age of 18 months to two years, they are adolescents. From that point until they are 75 percent into their expected life span (which varies by size and breed of dog), they are adult dogs. For the last 25 percent of their expected lifespan, they are considered senior dogs, when they are also said to be in their golden years, or referred to as “gray hairs”.

What are the adolescent years for dogs?

The adolescent years for dogs are the end of their first year until somewhere between halfway and fully through their second year of life. Sometimes, people refer to “puppy adolescence,” but the adolescent phase is a separate time of life that comes after the puppy phase. The dog adolescent ages are the ones that many people find the most challenging.

That is saying something because the puppy phase is the one that usually involves potty messes and sleep deprivation, yet it is still not as hard for most people as the adolescent phase.

The dynamic between adult and adolescent dogs

Adult dogs respond differently to dogs of other ages, so dog life stage matters to dogs, too, and not just to people. Some adult dogs are afraid of puppies, or even disinterested, but it’s common for stable and well-adjusted full-grown dogs to have an attitude and behavior toward puppies that is best described as indulgent. Many adult dogs let puppies crawl all over them, bite or bat at their tail and ears, take their toys, and disturb them no matter what they are doing.

But then the “puppy license” wears off when the puppy reaches early adolescence, and dogs are less likely to tolerate certain behavior from young dogs. They are very clear about what is acceptable and what is not, and they set clear boundaries. Adults shouldn’t be too rough, and usually aren’t, but some adolescents do become alarmed by the sudden change in the behavior toward them by adult dogs.

This change involves adult dogs who react very differently. It’s not only normal — it’s desirable. There’s no better way for a young dog to learn some manners than to have a socially skilled adult dog set clear boundaries.

Humans also do this boundary-setting. When a baby grabs at earrings or pokes an adult in the eye, the adult’s response is minimal. But a seven-year-old who does this is likely to receive instruction on appropriate behavior. Ideally, such instruction is given kindly and fairly to young humans and young dogs alike.

The dog adolescent phase: What to expect

When your dog enters adolescence, expect behavioral changes. It’s completely normal for them to act differently as they enter the transitional period between puppyhood and adulthood. Transitions of any kind are hard, and this is true with developing dogs.

Just like human adolescents, dogs can have a mild or extreme experience with their transitional years. As a pet parent, this period can be a shock, since it comes right on the heels of the adorable-puppy stage. Sure, during a dog’s puppyhood, there are usually some accidents and interrupted sleep, but your puppy’s cuteness largely distracts you from viewing this as a terrible part of dog parenthood. People are rarely blindsided by the trials and tribulations of puppyhood — nobody is surprised by the occasional chewed-up shoe.

Not so in adolescence. This is the time when many of the kindest, most patient dog parents in the world are left wondering where their sweet puppy has gone. There’s an understandable urge to say, “Who is this monster, and what have they done with my dog?”

What behavioral changes can I expect during dog adolescence?

1. Independence

People are often surprised by the sudden independence of their adolescent dog. Gone is the shadow pup whose first choice of where to be was always right next to you. Dogs emerging from the puppy stage tend to explore more, wander further from you than they used to, and care less about keeping you in sight.

It’s hard to see your dog acting independently like this because it can feel like they don’t need you — or even as if they don’t love you as much. Don’t let it get you down; despite these behavioral changes, your dog loves and needs you just as much as ever, but also likes to do their own thing and follow their nose. (I don’t know who needs to read this again, but your dog still loves and needs you.)

2. Being less responsive to cues

Often, adolescent dogs seem to have forgotten everything you worked so hard to teach them. They ignore cues, respond to them more slowly, or act as though they forget what some of them mean at all. I know it’s difficult, but don’t take it personally. What feels like a training setback is completely normal in adolescence, so try not to settle into gloom and doom or feel like all is lost. Your puppy is just growing up, and this, too, shall pass.

Even if you know to expect it (and especially if you don’t), it can be quite a shock the first time your adolescent dog acts like they didn’t even hear you at all. It’s demoralizing, after months of enjoying your gleeful puppy running to you when you cheerily call out, “Come!”, to see no such enthusiasm. You gave the cue just like you have so many times before, you’re all ready to reinforce your dog with great treats or a chase game, and what happens? There’s no reaction — none at all, not even an ear twitch. Sigh. That perfect recall that brought you such pride seems to have disappeared.

The same dog who sat in a heartbeat when asked now looks at you as though considering their options: “Yeah, I heard you, but I’m simply not interested in doing that right now.” Don’t be surprised if you give a cue your dog knows well, and the response is a blank look as though they’re completely unfamiliar with this cue or the behavior associated with it.

Don’t panic when you see a training slump in early adolescence; it’s a common — and temporary — phenomenon. The work you’ve put in with your puppy will pay off later. The well-trained, responsive puppy is likely to mature into a well-trained, responsive adult, even if the adolescent in between bears little resemblance to either. As professional baseball player Earl Wilson said, “Snow and adolescence are the only problems that disappear if you ignore them long enough.”

3. Increased fearfulness

As dogs approach the one-year mark, many temporarily become more fearful. Dogs who begin to act skittish or nervous but were previously confident are probably entering this developmentally normal fear period. They may shy away from people with hats or sunglasses. A toddler shrieking and running towards them may prompt your dog to run the other way.

Waiting until full vaccination to socialize can cause huge problems for your pup.

Most dogs move past this fear period without any lasting effects, just as kids stop being afraid of monsters under the bed once they move past that developmental stage. We can help all our dogs cope better by staying calm, resisting the urge to panic, and talking to the dog in a cheerful way. Don’t force them to approach or interact with anything or anyone that unnerves them, and pair up their triggers with something that makes them happy such as great treats or toys.

4. Adult dogs setting clear boundaries

Some sweet adult dogs indulge puppies by doing nothing when the little one nibbles on their ears or bats at their nose, takes their toy or uses their tail like one, or tries to play when the adult dog is clearly ready for a snooze. When the puppy approaches adolescence, the adult dog is likely to let their young friend know that this behavior is no longer acceptable, perhaps growling if the younger dog is being a pest, using their paw to swat at them, or even nipping with a gentle bite over their muzzle.

Most young dogs quickly learn what is allowed and what is not. An adult dog who gently offers young dogs a good social education is an asset. “Gently” is a crucial word here. It’s essential that the adult strike the right balance — firm but not rough. The adult dog should be guiding the younger one, never scaring or hurting them, but simply letting them know there are new expectations about how to act now.

Dog behavior is not static.

Many behavioral differences are predictably related to age, with especially big changes occurring during adolescence. They’re easier to handle if you recognize these changes for what they are: a normal part of development. We naturally do this with humans, but often fail to give the same courtesy to dogs. Adult dogs understand the change from puppyhood to adolescence and react accordingly. Perhaps the best course of action is to follow their lead.

How can I handle my dog’s changing adolescent behavior?

It takes patience and an adjustment of expectations to handle your adolescent dog’s challenging behaviors. Being patient here really just means giving your dog a lot of grace and remembering that adolescence is temporary but the love you share is forever. Dogs at this age have busy brains, and they are easily distracted. They are not ignoring you on purpose, but they are so tuned in to the world around them and they simply don’t have the bandwidth to give you the attention you became accustomed to in the puppy stage and that you will see again as they mature.
