I bought the G7 Jogger for my 12 year old, 30 lb, Tibetan Terrier.  He has degenerative disc disease and can't walk quite as far as he used to.  This stroller is PERFECT for us!  We've put about 3+ hours on it since it arrived last week.  It's a smooth ride, and super easy to push.  I haven't had to close the canopy during a walk, but it fits like a charm with a few inches of space above his head if he's sitting up straight.  Cupholders and storage area will come in handy!  So happy I took the plunge and bought this.
