Standard Stroller
If you plan on taking normal walks with your pup, then you likely don't need anything more than a standard stroller - as opposed to ones that are more specifically rated for athletic use. These are great options for the vast majority of people!
Jogger Stroller
For those who plan on running with their dogs in tow, check out strollers that are made for jogging! These tend to be more lightweight and sometimes have specific features geared towards dynamic agility - making them easier to turn and maneuver when going fast.
For example, jogger strollers typically have three thinner wheels to a regular stroller's four, and the front wheel is lockable assisting with maneuverability and stability, if these are qualities you're looking for! Jogger strollers also typically have wheels filled with air, compared to standard strollers which have wheels made of foam. The air-filled wheels will be lighter and bouncier but may stand a chance of popping or puncturing upon direct impact - just something to keep in mind.
