Great quality, don't know how it would hold a 70lb dog though. We have two small dogs (12lbs each) and they barely fit in together due to narrowness of the stroller. Biggest issue is the front wheel doesn't pivot. We have to lift the front wheel up to turn the stroller around the corner which is a pain. Cup holders are also only about an inch and a half deep so nothing sits well in them. Ride is smooth, easy to assemble
