For the past few weeks now, I've been letting Hiro run around an open field behind my townhouse. He loves being able to run freely. I know Shibas should never be off leash, but so far I haven't had any issues. I always make sure that I bring plenty of treats with me when it's time to go back home.
When spring time comes and the groundhogs are out, I don't think I'll be able to let him roam free. There was one time awhile back when Hiro first saw a groundhog. He didn't chase after it. He slowly approached it and ran away after the groundhog made a "yelping" noise.
I'll have to take a video of Hiro enjoying his freedom. Are you able to let your Shibas off leash outside of the dog park?
