I saw you talking about breaking Fi's heart by saying no pup right away, so not that you asked for it, but here's my opinion on getting a dog right away (and you can tell your Fi that your dog crazy friend said this so you aren't the meanie)
I would really recommend waiting for several months after you guys get moved in and settled before getting a dog. The animal is already going to be very stressed when you bring it home and any changes of routine can only make it worse. You guys need to establish a routine before you should get a pup to make it easier on yourself. If you guys have any fights, even stupid play fights, it could really set the dog off thinking there is conflict and it might react poorly. It also can really confuse them if you are rearranging furniture and things like that which is just another reason to wait for a bit.
Holidays can also be really rough on pets, especially if you are planning on travelling or having people over. More established pets often have fun with house guests but a newbie will just be scared shitless the majority of the time and think the house is under attack.
Also, like another poster said, potty training in the snow sucks asss. Really having a dog in the winter kind of sucks. Nothing more fun than going out every 30 minutes in freezing temps and coaxing a dog to pee, only to have them refuse to do so and pee inside the house where it's comfy. Not something you want to encourage!
