Moki is almost 7lbs. Just under but has alot of Muscle...on his frame...for a Yorkie. We hike all the time. But I hike so I need my pack for water , food and the other necessities. Another pack for my dog wouldn't work. But I have a sling. If you any reason I need to pick him up its easy to carry him. He walks anything under 5 miles easy. Just whatever you choose makes sure you do neighborhood an park hikes first before you go into the bush |
