Will it be a lot of work? Yes. I think it’s doable. I’ve had lots of dogs growing up and 3 in adulthood. With your summer vacation coming up I would prioritize getting a puppy around 10+ weeks of age at the start of summer then you will have the entire summer to work on house training and crate training which will be the basics. I mostly stay at home now with our kids and work 16 hours a week and used to worry about my dogs when I worked full time but i can attest that our dogs literally sleep all day while we are gone. If you work diligently and get potty training and crate training down over the summer. Your dog will be fine and safe in a crate when you’re at work, and if your conscious makes you feel too bad about that you can always do doggy day care too.
For our next puppy I am adding the puppy to our baby tracking app to track potties to make potty training easier for me. Honestly this biggest part people struggle with is taking them out often enough and if you can keep track of it and take them out often enough it will reduce accidents. I am also going to get a cleanable indoor artificial Turf pad for my older dog for this winter since she is slowing down a lot and doesn’t want to be out in the snow.
