It sounds silly, but you have to consider how social your dog is, and also how adept at swimming and re-entering the boat should it decide to actually go retrieve something.

If your dog is basically a lazy, sleepy, lab who will stay put, then you can build a double kayak with two cockpit holes. However, if your dog wants to come and sit at your feet, or go swimming, then you need a design with a large cockpit which will hold two, or maybe two people and a dog.

You can easily keep the hull design of any good double, and modify the deck to have either seating arrangement, but if this is the firsr boat you'll be making, then it might be nice if the plans showed the type of cockpit you need.

Other than that, can you tell us your weight, height and is your shoe size bigger than 11? This way we can suggest a design that might fit you. also, do you have to carry the boat far to get it to the water? Is very light weight extremely important to you, or is a 40 pound boat as good as a 35 pound boat?
