Is there any chance of either of you working from home during the week? Even a couple of afternoons would make a difference to break up the dog’s long days, and if you could rotate with mrsconsequence it means the impact on each of you is relatively minimal.
The other thing you would need is a walker, IMHO, every day, to come around midday to exercise the dog, wear it out, give it some excitement and so on. And obviously, when you’re home make sure you spend quality time with it.
It’s not a panacea, but realistically if working 8 or 9 til 5 every day precluded having dogs, there would be far fewer people with pets.
