Because I'd rather copy/paste, I looked through several sites, and here's a mixed bag of what they say, which I agree with.
I looked under 6 months old, because it's about the start of it. How old is Evie now?
Here's a cross-section of information about this stage:
Your 6-month-old puppy is an adolescent now, and their behavior may show it. He may have an increase in energy and willfulness.
Puppies between 6 and 12 months of age may sometimes act like they "forgot" their training. Be consistent and firm. Continue to have regular training sessions, covering the old basics again, and mixing in newer, more difficult tasks.
During this period, it’s a great idea to keep one thing in mind:
Always. Be. Training
As your puppy’s personality develops, now’s the time to double down on teaching (and practicing) skills and developing a solid, respectful relationship.
Recent research has shown that dogs do go through a rebellious adolescent phase, and they can be just as obstinate as human teens as they navigate fluctuating hormones and push for a bit of independence.
Changes in your dog’s brain can cause some challenging behaviors (it’s not a coincidence that this age group is the most likely to end up in shelters in the U.S.). It’s important to remember that your dog hasn’t forgotten everything they’ve learned and they’re not “trying” to act out. This is part of growing up, and with some help, your pup will emerge a happy, confident dog.
Exercise for the body
At this age, your pup is a ball of energy, and it needs to be channeled. It’s essential to provide your “teen” with ample exercise every day to ward off bad behavior. You may have heard the expression, “a tired dog is a good dog.” This will become very evident during this phase.
At six months, aim to walk with your dog for 30 minutes twice a day. Save the strenuous hikes for when they’re a bit older.
Look for opportunities for indoor or backyard exercise in the form of play:
Play (and teach) fetch in the yard or your hallway.
Play hide and seek. Hide treats or coveted objects around the house. Tracking them down will keep your dog busy, and burn energy. The game can also be a way of distracting your dog from you.
Exercise for the brain
Mental stimulation is as important as physical exercise.
Work on training skills a few times a day. Keep the sessions short (5-10 minutes) so they’re fun and not frustrating. Consistently train and add in new skills and varying levels of distraction, making it more challenging for them to complete the “assignment” successfully.
Another way to keep your dog stimulated (and out of trouble) is through puzzle toys, which can be stuffed with healthy treats. You can also use your pup’s food in these toys, turning mealtime into yet another brain-testing session.
Remember to give your dog time and patience. But don’t ignore any issues that crop up, assuming your puppy will grow out of it. If you’re struggling to manage an emerging problem, seek the help of a trainer.
6-Month-Old Puppy Behaviour
Your puppy is essentially a teenager at 6 months old. They will likely be energetic, playful, and much more independent.
It’s also common for puppies to get a bit rebellious and destructive during this stage of development. They may start regressing in terms of training, seemingly “forgetting” all the things you’ve previously taught them.
Try not to get disheartened and continue working on your pup’s training. Be consistent and repetitive with sessions, and above all else, don’t lose hope! Your puppy’s naughtiness isn’t personal, it’s just something that happens during the adolescent stage.
You can help reduce mischievous behaviour by ensuring you provide your dog with plenty of physical and mental stimulation for curbing boredom in rascal pups.
If your puppy jumps out of his skin when a plastic bag blows by him on a walk, he’s exhibiting a normal sense of fear. If you notice that your puppy is suddenly afraid of the pillow on the couch, this is a sign that his Fear Imprint Period has begun. Puppies go through several developmental periods and during this period, your puppy is susceptible to conditioning from pain and fear.
Every time a fear period happened with Krypto, it took me by surprise. I shouldn't have been surprised, but I was. Every time.
Everything would be going along fine, and then he'd suddenly be afraid of a common item in or out of the house.
Well, I'm sure that you know most of this, including how to handle a fear period, but if you get stumped at any point, we're happy to help as best we can!
