I'm considering adopting a smallish adult dog. I live with my husband and two adult cats in a good sized condo in a suburban area. This would be my first time as a dog owner. For those that have dogs, what kind of changes did you need to make in your lifestyle? What did you expect/not expect?

-I work from home 2-3 days/week, my husband is home every afternoon mid day plus one full weekday
-I have 2 adult cats who've tolerated/ignored mellow dogs who have stayed with us
-I do travel 6-8 times a year. My husband travels twice a year.
-I do not have a yard
-No children

Thanks for any tips or advice!
