I'd advise against a puppy, unless you have time to train, house break, chewing etc them. a 1.5 year old is still young but old enough to work with. We use to try and adopt puppies but they are time consuming. Time spent looking for our latest pet was equal to buying a truck, research and pounding the pavement.

Regarding a "wolf" hybrid GFL. Having been involved with the "breed" you will need a few things before bringing one home
1) Very secure dog run, easy 10x10 minimum.

2) Very secure dog run, making sure the top is covered and you have at least 6-12" under the pen secure with fencing and or brick.

3) very secure dog run. The "hybrid" outside of being a pack animal is a very good escape artist. They like to DIG and JUMP. The 2 i had hands on experience turned their shelter into a labyrinth of tunnels and hiding spots.

4) No other pets especially cats. In their heart they are hunters, if it moves it's a meal.

5) Lots of time dedicated to the "breed" no matter how hard you try to train it, they have a mind (wandering) of their own.

6) Do NOT buy any new furniture or think about making the hybrid a house pet. They are not and house breaking one , or trying to, is like the Borg, futile.

This looks like you are going to buy a BMW of pets, STAY AWAY unless you do a lot of research and spend time with one of the wolf rescues. They are a handful and you more than likely will be trying to find a home for it within the year.
