How far can puppies be walked daily?

[Steve Drury]

Our Daisy (10 days shy of 8 months / medium goldendoodle) graduated from her first obedience class this afternoon. When talking to the trainer after the class I mentioned I have been walking her almost 2 miles daily for the last 5 or 6 weeks.
He said she was too young to walk that far as she is not fully developed skeletally. He said the prolonged impact of a walk on concrete at this age could result in problems when the dog is older.
His suggestion was less than 1/2 mile daily until one year old.
Has anyone received similar advice from their vet?
We'll call our vet tomorrow----but it is on my mind right now.

You could always use your treadmill for Daisy (if you have one) that would be a lot less impact than outside.

UPDATE: the official response from Daisy's vet: the 2 mile walk is great; it is actually beneficial in that it builds up and stengthens the leg muscles surrounding the joints. Proper muscle mass and tone will provide increased protection against injury. He politely suggested that though the trainer was well intentioned---he should stick to what he knows best and leave the health education to the vets. Daisy will be as pleased as I am. It's one our favorite parts of our day.

Wow, Steve, you have me worried. My doodle Thomas has been involved in a 1 1/2 hr dog run for 4 weeks now. He goes every Wed. and Friday to an off leash dog park for a 1 1/2 hr walk/run with 10 other dogs in his group. The park is a conservation area, very hilly, with trails through wooded area. Its been covered in snow and ice up until now as we are just outside of Toronto, but these dogs run and play together like a pack of wolves. Great exercise, I thought-he is so tired when he comes home. But he is only 5 1/2 months old as of tomorrow!!! Am I asking too much of him?

My vet, and my breeder both recommend one mile and under until one year of age. Working gradually up to the mile. In addition other "forced" repetitive actions, like jumping repeatedly for a frisbee, should be limited to three or less. Some breeders and vets even recommend against jumping into and out of the car, on and off the bed, etc until one year old. I think common sense applies here.
