Growth Plate Closure - Range (days) Closure - Average (days)
FORELIMB
Proximal radial epiphysis 136-330 258
Distal radial epiphysis 136-510 318
Proximal ulnar epiphysis 161-450 258
Distal ulnar epiphysis 217-450 308
The smaller the animal the quicker the growth plates will close. So you can see from the chart that there is a HUGE range in how quickly growth places will as we all know that a Yorkie is on the smallest end of the scale and we go up from there. It is not just dogs that have growth plates that close over time all mammals do such as an elephant. Which BTW I just learn because they are so large it might take years for their bones to fully close.
