Generally speaking if you feed an average quality dog food and the pups are  getting in the sunshine you won't have rickets.    If you are really pushing puppies nutritionally "more often in larger leggier breeds" you can have them outgrow themselves, that is their bones are growing faster than  their muscles, tendons, and ligaments can keep up and it will cause them to be crooked legged appearing to have rickets.

I think that is why there are so many performance and race horse colts broke down, 2/3 yr olds  are too big and strong for their maturity levels. Most of the endurance horse competitions have a minimum age of 5 yrs old. Way back in time they usually didn't break horses until 4 yrs old they were largely range raised not pampered and pushed from weaning on.
