I got no dog and no little lady or little sir, and I have been working at home for 17 years with no problems. But, to tell the truth, my work rarely need to be synchronized with others. Very few meetings.
I only have a good lady, that is also working from home, and we try to not interrupt each other too much.
That is quite good that both of you are working from home. I am normally much more focused. The snow always brings out the excited child in me!
