Bringing home a rescue - going from senior to (older) puppy

Just under three months since we lost our sweet Chase, we are lucky to bring home a setter rescue early next month! We are very excited - he is young (1.5) and has lots of energy which will be great for our active family (I hike every weekend, we walk daily, I have a very lively 5 YO) but a huge change from out ~14 YO senior. This pup is crate trained, potty trained, and working on leash training (which I have some experience with). We are enrolled in a level one obedience class. The foster gave me a heads up that he’s “a bit of a tornado” and will need to baby proof the house…besides securing/hiding exposed cords, keeping toys off of the ground, and clear hazards, what should we be doing? We are making all changes to our house layout now to be sure everything is comfortable for his arrival. Anything should we keep in mind when bringing home a doggo this young? Thank you!!!
