Charles939. We use a Pet Gear stroller and are real happy with it.
For the unhelpful answerers - I imagine there are many reasons that someone would want to put their pet in a stroller vs walking them. Here's ours,- We started using one when our 13 yr old dachshund Snoopy couldn't walk far in campgrounds. We also had a dachshund puppy Minnie that decided if he could ride then she wanted to also. Snoopy has passed and Minnie is now 3 1/2 and still loves to ride in the stroller. Now we have discovered that she is much more secure and safe in there vs walking on the ground, especially in stores or around crowds. Other dogs and children can't go running up and grab her easily. We still walk her on a leash but we often use the stroller. We've recently gotten a kitten that we want to keep as an inside cat and plan to include him in stroller walks when camping.
