If you are going to add a dog, please don't do so as a prop for one or two scenes, unless for some reason the dog is specifically that: a prop for the character to use to get someone's attention. Which does speak to the kind of person your character is, doesn't it? Also think about your character's personality. Are they strong willed, or wimpy? Do they cave in when yelled at or do they stand up for their rights? Using their interaction with their dog, or their choice of dog, gives you a great opportunity for subtext.

Dogs need regular exercise. Both the going to the bathroom sort (and don't forget the pick up bags unless you are showing a negative aspect to your character) and the moving around with energy sort of exercise.Big dogs can live in a small apartment in the city but it's not easy, and it takes a lot of effort. Leaving a dog confined for too long can be cruel, especially if they have are fastidious, most especially if you don't want the house to smell when your characters come home for an evening of people interaction. Nothing turns off a non-doggy person so much as doggy smells.
An untrained dog is not fun to run or bike with; you might add a line or two about how easy or difficult it was to bring them to a safe level of cooperation. If the dog was a rescue, did they come with trust issues, or maybe they were already trained and had been turned in due to circumstances beyond their former owner's control?
If you want to add personality to your characters, you might think about incongruous choices for your character's dog. A large, tough, man with a small dog is good for a giggle or two but it's not necessarily out of character. Dainty women with guard dogs they can't control don't appeal to me, but that dog, well trained, maybe left with her by someone who had to go away (maybe a brother who was deployed?) I'll go along with that story line, no problem. Hmmm, just a second, I want to jot that idea down.
