Dog Strollers

[Uni]

I am interested in buying a dog stroller (my oldest has lower back problems and cannot go for long walks).  I plan to take it to the parks, greenways, etc.  I would also like it to be big enough to fit both dogs (60 pounds total) if the other needs to get in.  Does anyone have any recommendations or suggestions on what to look for when buying a dog stroller?  Any tips will be greatly appreciated.

I don't know anything about dog strollers except the ones I have seen are fairly small.  I think you wouldn't need one for both dogs if the other one is healthy - I don't think it would be like kids wanting in a stroller because a sibling is. I think dogs prefer to walk independently.  If I were walking two dogs, I would limit my distances to what the healthy dog could do and push the older dog in the stroller.
