Lovely journaling, I know where you are coming from with the mixed emotions over getting a new puppy. Lovely photo of Jack, love the paint and triangle paper pieces.
I'm so sorry about Jack. The loss of a beloved pet is as hard to get used to as losing a family member or favorite friend. You have created a beautiful layout in his memory using soft colors and a number of special accents in his honor, like the golden heart and the butterfly. Jack would not want you to be unhappy or to feel guilty on his account. He loved you, and he wants you to be happy, like he is up in doggie heaven. Please welcome the new puppy with open arms, and he or she will help you heal.
