Pitbulls and Dog Packs

Submitted by mdrebin on Tue, 08/09/2011 - 15:43

What are people's thoughts on Dog Packs for Pitbulls? While not huge in size, they are quite muscular and working dogs.. With proper introduction to the item, it seems having a little extra work force (even more so if on a slow walk / hike) would be a great thing. Thoughts? Suggestions? Experience with such?
