If you're not 100% committed and prepared to do all the grunt walk, then please don't get a dog. They are a huge tie and a lot of work, especially for the first couple of years.
There are regular threads on here from women who've agreed to get a dog because their DC/DH want one, and now they're stuck doing all the work and are seething with resentment. So please, please think it through. There's a lot to think about when considering dog ownership.
Cost - food, injections, flea/work treatment, insurance, toys, equipment, chews, threats, training classes, dog walker, kennels or boarding when you go away or want a day out, replacing the stuff they've chewed or ripped holes in, grooming, dog towels, coats etc.
Time commitment - walks, toilet training, getting up in the night, not being able to leave it alone for long periods, no spontaneous trips to the zoo or theme parks as you can't leave the dog alone, having to rush back from work or school or activities for the dog, planning trips out well in advance as you need to source care for the dog...
Just don't underestimate what you're taking on. Also, like a PP said, I don't know a single dog that doesn't have some kind of issue - reactivity, noise sensitivity, hates traffic, needs a special diet, hates the groomer, has no recall, eats poo etc.
