trail running

[roadie gal]

I have been trail running for a long time, love it! My puppy is 10 monthes old, I am thinking about taking her with me to the trail.
She got all the shots she need, she is a big girl, nearly 50 lbs. Are there anythings else I should know but bringing the leash and water?
Any input will be greatly appreciate.

A lot depends on the type of dog. 10 months might be too young to go for a long run. The bigger the breed, the longer you have to wait to run them. The giant breeds are prone to elbow and knee problems if you run them too soon.
