I have to agree with this:
DO NOT GET A DOG.
Dogs are very different than cats. They can't be left. They need to be walked. They shed. They are a LOT of work.
Get another cat and leave it at that.

PS - I have a corgi and he's the best dog ever - but he sheds... a lot!
I have a 10 yr old son and 6 yr old daughter. Son always wanted a dog. Husband always wanted one. I did not because I knew most of the work would be on me. My daughter finally made me cave.
We got a big black lab (rescue) who came well trained. She came crate trained, meaning she likes her crate and goes into it when commanded. Some rescues have "issues" - ours does. I did NOT want a puppy. It's like having a newborn. She is sweet, but needs a lot of walking. I take her fetching at 6 or 7am (her first pee). It's a good thing I'm a morning person. We don't leave her outside in the yard like a lot of people do. What if she bites someone who comes to the front door (back yard/front yard are not separate)?
I had to hire a dog walker for the 10am walk ($60-75 per week) because I'm usually out and busy. But then I have to make sure I am home by 1 or 2 for that walk.
On weekends if we go out for a day trip, we have to hire a dog walker ($15-22 per walk) for the time we are not home. That means typically 2 walks during the day. It's a real pain for me to feel tied down like this. Last weekend I called 3 people and they were not available (last minute day trip idea).
PROs
It has been a wonderful experience for the kids to learn compassion and practice it for another living thing. They LOVE the dog. Our lab loves to be rubbed and loves attention. Kids and their friends cuddle her all the time.
CONs
the constant walking and attention usually provided by yours truly. Ours is an indoor dog and thankfully doesn't bark. But we have had other issues. Having to rush home to walk her is a PITA.
I wish we could get a cat (I'd get 2), but hubby doesn't want to because he's afraid of them getting outside and becoming coyote snacks.
ALL dogs need exercise. Start watching the DOG WHISPERER and that's one of the first things he'll say for a healthy, mentally balanced dog. He says that they need at least an hour of walking a day. Can you provide that?
My SIL has a mentally disabled child and got a lab from a retriever training program that was rejected (he was too excitable). Her son loves that dog and the whole family loves that dog. She walks him 1 hour a day (her son loves the walks) so it works out. I wouldn't want to do that.
