I am able to teach your dog how to “Bike-jor” also called urban mushing, this experience gives your dog the ability to learn something new, run however fast they want to run (great for dogs that love to pull or just plain run fast). And give them a little weight/ endurance training! Contact me if you like the idea of a tired/ happy dog! Also, I have no problem with big “scary” dogs. I have experience dealing with dealing with aggressive pets, and after I’m done with ‘em they will be too tired to bark/jump (be bad) to also even get off the couch! I can even check on your other pets if you desire, feeding fish, cats, snakes or any thing else! Because who says are hearts are just resurved for dogs?
