Loved it, 4.5/5 stars. My boyfriend has a slightly energetic australian cattle dog and this pack settled her down so much. She pulled less, seemed more focused, and now that we're home she's sleeping soundly. The only reason I wouldn't give 5/5 is because it did get slightly lopsided at times, but generally straightened out whenever she shook. Might try some different weights inside to help with that and experiment, we used canned beans for our first trip out so maybe it was just the awkward cargo making is more prone to lop-siding.
