And so yes the long bones grow longer if the growth plates don't close... or close late..........


Now logically in small under 10inch tall dogs the effect would most likely be minimized (and btw dwarfism is a different kettle of fish), But the relationship of a long femur to a standard or short tibia, would again logically see the articulating surface relationships between these two bones alter; and as the patella tracks between the base of the femur and the top of the tibia it is interesting to imagine how the patella might be affected.

Jodi posted an article about it that says after spraying or neutering the growth plates still close.....
