Both Nala and Sherman are adorable. Congrats on your new dobie puppy.
I've always started my puppies early on the least, at least getting them used to it. I'd say 11 weeks is not too early to get them used to the feeling. I have no clue how soon Jordan was started but at 14 weeks when we got him he was very comfortable on the leash and I think will train very well on it. We do mostly loose leash in the yard at this point because I don't know his vaccination schedule before hand but once his shots are up to date to my comfort I'll get him out for more formal walking and training.
