This bag fits well with the use we wanted, ie that our Doberman bitch 8 months bears affairs, including a bottle of water for the ride and little hike. it perfectly acceptable to the load even if at first she stay a little surprised, and lets himself go to tie the straps. we must attach the straps for the bags do not move, and distribute the load evenly quoted 2 otherwise the bag slides. practical and functional, good value for money.
