Nervous about potential size of a rescue puppy

I had a dachshund for 16 years and fostered a few over the years. I’ve really missed having a dog, but it took me a while to heal after losing mine.

I loved her size and she was the best cuddle buddy, but she couldn’t keep up with my active lifestyle (hiking, outdoor sports), and IVDD was always in the back of my mind. Because of that, I’ve been thinking about getting a slightly bigger dog.

I recently found a Potcake puppy on a rescue site and totally fell in love. I applied and have an interview tomorrow.

My only concern is size. I live in a condo, so I’m hoping for a smaller medium dog. The rescue says she could end up anywhere from 25–60 lbs, which feels like a huge range.

She is currently 3 months old, 8 pounds.

Any Potcake owners here? How big did yours end up? Do many stay around ~35 lbs or under?
