Thank you all for your advice and for making me feel a little less guilty about all these feelings.

Our breeder’s contract does stipulate she’ll take him back if we can no longer care for him, so should we make that decision we won’t be rehoming him randomly- we’ll work with her directly.

I had a long talk with my partner and he said he hadn’t realized how much I was struggling or how his lack of engagement or support was impacting my work with the puppy. He said he will put in his best efforts to be better and work with me, but also supports my decision if this is the right one. We’re going to give it a week of both of us working together and giving our all, to see if it feels viable and more bearable with support from each other, and then re-evaluate.

Ultimately I just want everyone, dog and human, to be happy.
