This is great for two small dogs, or one medium size dog. Plenty of room has back screen so dogs can see you too. small hatch in front to deliver food and water, so you don't have to take the out. both my dogs are under 8 lbs., and both had plenty of room, they even napped in it. Reason for not 5 stars is I had the breaks on and my husband didn't know, and as he pushed the stroller forward, the breaks (made of plastic) broke in-two. This would not have happened if it was made of steel like the rest of the stroller parts, can't believe they would use plastic brake to hold these large durable tires when the bar they are attached to is made of metal. We duct taped it back together, but this was on first time using. We are going to see if breaks can be made by a welder, out of metal and do away with the plastic. But other than this flaw, its a great stroller for travel, walks, and the tires can go over everything, gravel, rocks, concrete, we've done it all.
