Yes it changes your life, but for the better. Given your work is pet friendly I would be all over that. I hate leaving my guy home all day, even if there is usually someone around the house.
I would say do a lot research into owning a dog, ie training it properly, general upkeep, exercise, care and so forth so you know what you're getting into time and money wise in the broad sense. It's not a massive commitment that will take up all your time, but it's an easy hour or two every day all told between going outside to do their business and then playtime, going on a walk/run and such. Monetarily it can easily be a couple thousand a year between foods, vet fees, toys and other items/fees. You need to be absolutely sure you're willing to provide the necessary care and follow through with training and socialization of your dog, otherwise you shouldn't get one. They're not just some accessory or furry companion you can buy and then deal with when you want to.
Then figure out what kind of dog you want to get. Puppy or adult, rescue or breeder, specific breed or not, etc. Getting a puppy is really great, but it's a much larger commitment of your time for the first 6 months or so as you have to really baby them, cause they're babies. Constant direct supervision, lots of training and house breaking work. Socializing with other dogs and people and situations. They will pretty much take up all your free time during those initial months. I really enjoyed it, but some people are willing to commit the time and that just leads to trouble down the line for you and your dog.
Unless there are issues of allergies and other traits you need to limit your search to I would urge you to go to a shelter and find a rescue dog to adopt. So I would look up and then visit all your local shelters and rescues and look at what dogs they have available to find the right one for you.
If you do find you want or need a specific breed or type and/or want a puppy please find a reputable breeder and thoroughly look into them to ensure they are on the level, as there are so many people out there operating for profit breeding farms that are not treating the dogs right and or doing what is necessary to maintain the health and quality of their breed.
