I work full time and have for most of my breeding career (24 years) When I have started a new job, I let them know up front that either my girls come with me to work when they are due or I stay home. All of my girls have either been shown or traveled to shows so are used to riding in the car and seeing new people. I set up a crate in my cubicle and bring my whelping supplies. If I am away from my desk, my assistant watches the girls until I get back and pages me if there is a need. I have had several litters over the years while at work with no complaints from coworkers or employer. When the puppies are little, I bring mom and puppies to work each day until I am sure that they can be left at home. I then just go home for lunch to let mom out and check on the babies. So far, I haven't had any problems with the moms or the babies. I have also found that puppies that go to work with my when they are very young are never car sick later in life. May be a coincidence but who knows!
I will be on puppy watch starting the 14th and already have coworkers asking when the mom -to- be will be coming!!!
Hopefully, you can work out a doable situation.
Best of luck.
