Query: Dog Pack

This pack doesn't quite fit my dog's dimensions, but nevertheless, it works. I have a 55 lb lean and long pit-shepherd (we think) and if I make the first strap (closest to neck) too tight it brings it closer over his shoulders but makes the other straps rub. I have found a combination that seems to work, but the two bottom straps will never be able to be adjusted snuggly. I am still satisfied, though, since it doesn't come off and I've found an adjustment combination that rubs the least. So- it works.As far as construction and amenities, I like the bungees it comes with and he pockets are big enough for whatever weight combination I should need and the zippers seem to be very durable.I've had this pack and have been using it for at least a month.
