* Breed: Different breeds of dogs have vastly different sizes, builds, and athletic abilities. A tiny Chihuahua will run much slower than a Great Dane puppy.
* Age: Puppies are still growing and developing their muscles. A young puppy will be much slower than an older, more mature puppy.
* Individual Variation: Just like humans, every puppy is different. Some puppies are naturally more athletic and energetic than others.
General Guidelines:
* Very young puppies: Will be very clumsy and have limited stamina. They might only be able to run in short bursts.
* Older puppies: Can run faster and for longer distances as their coordination and stamina improves.
* Small breeds: Generally reach their top speed around 6-12 months old.
* Large breeds: May take longer to reach their full potential, sometimes up to 18 months or more.
Important Note: It's crucial to avoid overexerting young puppies. They are still growing and their bones and joints are delicate. Let them run and play, but be mindful of their limits.
