        How JBK Focuses on Puppies and Bone Growth

​

Today, we are explaining why intense physical exercise should not be pushed too early in growing puppies, especially before full skeletal maturity.

​

Puppy growth rates vary widely by breed and size. Diet, exercise, body condition, and daily management should be adjusted to the individual puppy in order to support proper skeletal development.

 

Endochondral ossification, the process in which cartilage is replaced by bone, occurs over different timelines depending on the dog’s projected adult size. In general, growth plates close much earlier in toy breeds and much later in large breeds.

​

Many factors influence growth rate and maturity, including breed, size, sex, nutrition, and overall development. Males often mature more slowly than females, and larger breeds remain physically immature for longer periods. Because of that, repetitive impact, excessive exercise, poor conditioning, and bad management during development can place unnecessary stress on growing structure.

​

For that reason, puppies should not be pushed into hard, repetitive, high-impact activity too early. Fast, repeated ball chasing, hard jumping, repeated sharp turns, jumping on and off furniture, and jumping in and out of vehicles can all place unnecessary strain on immature joints and developing growth structures.

​

If the goal is future performance work, including agility, flyball, or other impact sports, training should be approached carefully and age-appropriately.

 

Mature structure matters. Developing puppies benefit far more from controlled movement, confidence building, body awareness, socialization, environmental exposure, and learning how to use themselves correctly than from being pushed physically too soon.

​

This is one reason responsible breeders tell new owners not to rush physical activity in a growing puppy. There is plenty to work on before high-impact exercise should ever become part of the plan.

 

Use the puppy’s mind first. Build confidence, engagement, stability, environmental exposure, and controlled coordination.

​

Once the dog is further along in development, consult your veterinarian before beginning true impact sport training or repetitive jumping work.

​

And yes, feet matter.

Proper nail care is part of structural management. Nails that are left too long can gradually affect foot shape, toe position, and how the dog carries itself. Owners often do not notice the change at first, but over time poor nail maintenance can contribute to abnormal foot mechanics and additional wear on the dog.
