I have this stroller, it looks like it's the same as the flower one
New Large 4 Wheels Pet Dog Cat Stroller 18 Color Choices with Free Rain Cover | eBay
It suits my needs perfectly, I'm mostly on smooth pavement or in stores with it. If you're going to run with it or be on rough gravel a lot you might want a better one.
A local store sells pet gear and gen7 strollers for much more, I think mine is as good or better.
My only complain is it doesn't have any tethers. I made one with a leash, I only use it if I have the stroller open, if it's zipped shut I just leave her leash on.
How big are your dogs? Lola is 7lbs and I could fit 2 of her in it, 3 of her would fit but wouldn't be very comfortable.
A lot of people on here have this stroller, some have had issues but people seem happy with it for the most part.
The reversible handle is nice, but I don't think I'd bother spending the extra money on it, the cheaper one has a mesh screen on the back so you and your dogs can see each other.
