OP, it’s an excellent decision.
Although I have kids, I’ve had a few miscarriages and a stillborn daughter which will always leave me with a sense of sadness, damage, and failure (just to add: these are my feelings, not putting them on anyone who goes through difficulties around conceiving).
I found myself struggling with the loss of fertility and the end of trying for babies as I got into my 40s. And I do think that if I’d popped out kids easily, I may not have struggled with my baby making window closing.
Anyway, we got a puppy (going on 4 years ago now). Oh my goodness, he is love, therapy, companionship, and joy on 4 legs. He’s the glue that binds us and he’s just totally loved and treasured by us. We have time to dedicate to him, which is key. So if you’ve got the time and the desire to really invest in and engage with a dog/pup, go for it!
I work part-time. I’m out of the house for a total of 4 hours a day in two separate chunks. So I walk our dog in the morning and again in the afternoon (2hours a day in total). Ours is a chocolate lab-vizsla cross.
Look into breeds and really do some investigation. You want to get a breed that’s ok with(eventually) being home alone. Labs are the best all rounder, in my opinion. Vizsla purebreds can be a bit anxious. Ours is called a vizslador (I never use this term) and he’s been an amazing friend. The cross tends to work really, really well.
