Dog Stroller (Van nuys)

I'm looking for a dog stroller. Doesn't have to be perfect. I'm babysitting my aunts dog for a few weeks and it's a small chubby dog 🐕 , so I would like to take her for walks, but she gets a little tired. Haha. If anyone has one laying around I'd appreciate it greatly, if they could gift it. Thank you in advance.
