BEHAVIORAL CHANGES

• Primary Socialization Period (4-16 weeks): This is a crucial time for your puppy's development as they are like little sponges, absorbing everything around them. Puppies can form both good and bad associations, so it's important to use your judgment when introducing them to new people, dogs, and environments.

• First Fear Period (8-11 weeks): Your puppy is particularly impressionable during this phase. Any strong associations, especially those involving pain or fear, can have a lasting impact. Keep things positive to help them build resilience and adaptability.

• Clinginess: You may notice your puppy sticking close to you during this period. While they might eventually become a "velcro dog," it's too early to determine their long-term behavior.

TRAINING TIPS

• Socialization: Introduce your puppy to a variety of calm, friendly people, dogs, and other animals. Avoid overwhelming situations like chaotic parades and focus on quality interactions. Let your pup work through any wariness with non-threatening encounters to help them grow into a confident dog.

• Building Confidence: Gradually expose your puppy to new experiences, helping them learn that the world isn’t so scary. This will build their confidence and teach them to handle challenges with ease.

• Potty Training: Potty training is most effective during a short window in early puppyhood. Once set, it's tied to a biological function and becomes tough to change. Training an adult dog to potty reliably can be very challenging. View my Potty Training Guide.

BEHAVIORAL CHANGES

A puppy's first brush with independence, usually around 4 to 6 months, is like watching a teenager discover freedom—equal parts exciting and nerve-wracking. Suddenly, your once "velcro puppy" is testing limits and acting like they've never heard the word "sit" in their life. Just to add some spice, this phase also coincides with teething. Those baby teeth are on their way out, and your pup’s on a mission to chew on anything that’s not nailed down (and sometimes things that are).

TRAINING TIPS

Thankfully, most puppies are done teething by 6 months old, but until then, arm yourself with chew toys and brace for some gnawing escapades. It’s all part of the puppy journey, and with a bit of humor and a lot of patience, you’ll both come out the other side in one piece!

BEHAVIORAL CHANGES

• Adolescence and Independence: As your dog enters adolescence, typically between 7-9 months, they may become more independent and less consistent in responding to training cues. This phase is normal, so don’t be alarmed if your once-reliable pup seems to forget their manners.

• Second Chewing Phase: Teething might be over by 6 months, but a second chewing phase typically occurs between 7-9 months. Unlike the first round, this phase is more about exploring the world with their mouth than soothing sore gums. The chewing may subside around 9 months, but if your dog discovers that certain things are fun or tasty to chew on, they might keep the habit for life.

• Second Fear Period: Between 6-14 months, your dog may experience a second fear period, where they suddenly become wary of new situations. This can happen earlier for smaller dogs (around 6 months) and later for larger breeds (closer to 10 months). Allow your dog to explore at their own pace, offering reassurance without over-coddling, as too much fuss can reinforce their fears.

• Sexual Maturity and Behavioral Changes: As your dog hits sexual maturity during adolescence, hormones may begin to influence their behavior. This is often the stage where any aggressive tendencies could start to appear.

TRAINING TIPS

• Chewing: Be proactive in monitoring what they’re gnawing on and nip any bad habits in the bud. For more tips on dealing with teething, check out the Nipping & Chewing Guide.

• Maintaining Consistency in Training: Even though your adolescent dog may seem less responsive to training cues, it’s important to stay consistent with training. Remember, training is a long game with its ups and downs. Keep reinforcing positive behaviors and be patient during this phase.

BEHAVIORAL CHANGES

Smaller breeds typically reach behavioral maturity around 18 months, while larger breeds may take up to 4 years to fully mature. This extended development period means that larger dogs may exhibit puppy-like behaviors for longer.

TRAINING TIPS

Even as your dog approaches behavioral maturity, it’s important to continue reinforcing positive behaviors. Consistent training will help maintain training as your dog matures.
