Just remember to let curly know he is top dog. The pup wont know the difference but Curly will. Its hard with a puppy because just care alone makes you give attention to the pup like going outside. Always ask curly if he wants to go. At first he will- later he might say " I will just stay here" or he might decide its fun to go out and play with the pup.. Feed Curly first, give treats to Curly first etc. And if you say no- say the pups name so Curly doesnt think this is " aim" at him.
