Please don't jog that puppy!!!!
Your puppy is beautiful, but you are going to RUIN his joints if you exercise him like that! You're asking for hip displasia, etc. You're stressing his growth plates far beyond what they should be.
Puppies shouldn't be routinely jogged until they're much much older - talk to your vet. The fact that you have a large-breed puppy is just going to make this problem worse.
:eek:
Please guys, do some research before you cause permanent damage (hopefully it's not too late). Feed him low-protein dog food (NOT puppy food) so he doesn't grow so fast, and stop stop stop jogging him.
