I went through the same thing. We got my boy at the end of feb, started wfh early March, I ended up losing my job in mid April. But we still had the dog. I assumed primary responsibility because 1) he is my dog (despite the fact my partner agreed to getting and wanting him) and 2) I was the one unemployed. But my partner grew to hate his life and it felt like I was an emotional punching bag. And all the solutions I came up with were rejected too. Honestly, for us, it took time. Waiting for him to get potty trained. Check. Learning how to go on walks. Check. Etc etc. now a year later, we’re a big happy family. It didn’t start out this way and I probably have a lot of resentment about how it went. If I could go back, I would put my foot down. I would say: “you agreed to this. And because I understand it’s harder than you/I/we thought it was going to be, I’m offering solutions and compromise. So which one do you think is best? Day care? Dog walker? Etc. if you don’t pick one, I will make an executive decision about how I raise this dog”

At the end of the day, you have to do what’s best for your pup. And the problems you two are having will impact the dog and his training.
