Dog stroller/carrier (Kearny)

Hi everyone, I’m taking care of a dog with masses on her belly. I’m wondering if anyone has a dog stroller or a dome carrier similar to the Petgear 360 carriers. I’m looking for something to transport her around comfortably. The dome carriers are better because she can lay better in them and doesn’t have to adjust to the shape of a sling or bag, which is the case with the masses she has. If you have one that you don’t need or aren’t using anymore, it would be a huge help. Thanks!
