When is a dog not puppy anymore?

There's no single answer to this question, as it depends on the breed and individual dog. Here are some factors to consider:

Physical Maturity:

* Small breeds: Often reach full size by 6-12 months old.

* Medium breeds: Can take up to 18 months to reach full size.

* Large breeds: May take 2-3 years to fully mature.

Behavioral Maturity:

* Puppiness: Typically lasts until around 18-24 months. This includes chewing, nipping, excessive energy, and difficulty with training.

* Adulthood: Marks a shift towards calmer, more settled behavior.

Other Factors:

* Spaying/neutering: Can affect maturity, typically slowing down development.

* Individual temperament: Some dogs are more "puppyish" than others, even when older.

General Guideline:

While there's no hard and fast rule, most dogs can be considered adults by the age of 2 years old. This is when they are typically fully grown, both physically and behaviorally.

Important Note: It's always best to talk to your veterinarian for personalized advice regarding your dog's development.
