Hi! I have two mastiff's age 2 & 7.
I would
nevertake a mastiff jogging!
That is not what they are built for.
I know several mastiff's also in my area, and the people
that have allowed their dogs to run around all day with lots
of exercise and are now looking at huge vet bills. One now has
a torn crutiate and the other hip dyspasia. Also never let a mastiff jump up on things, like into a pick up.
Your puppy will take 3-4 years before it's full grown.
Limited exercise is great. Low impact walking etc.
Again, don't over do it.
Because Mastiff's are the sumo-wrestlers in the doggie world, you must be careful with them. Can you imagine a sumo type jogging? Same with a mastiff.
When my Beau was in his first year, I made sure he had limited exercise. When at the dog park, 20 min max to play.
We also took short walks of 10 to 15 min around the block, and played chase in the yard, where he was able to lay down and rest.
Remember our giants can overheat very quickly.
This site is great for some mastiff health

info on food, exercise, water, bloat etc.
Good luck with your puppy.
