I don't know that I can give any good advice as I am going through something similar with our loss of Aubrey; however, we knew we'd want another bully eventually. They are going to honor her warranty even though it is not certain that it was congenital, so we should be getting a puppy in the next week or so. I am completely back and forth with my emotions. Like you, the house is so empty without her and I still get upset thinking about her. Heck, I cried when I watered her garden and saw her stepping stone yesterday. On the other hand, I want something to help fill the void. A new puppy would never take her place, just like a new puppy wouldn't take Lola's place in your heart. I know that I will at first compare everything about it with Aubrey, but I want to give it the long, healthy life Aubrey didn't get to have, you know?
Getting a new pup is not going to solve your grief, but it may help you remember the happy times with Lola. Nothing can bring our girls back, but we can honor them by wanting another bully because we loved them so much, honor them by giving a bully the life we wanted for them. Honestly, I know that at times it will make it harder having another puppy around, but we can't close our hearts off from another bully baby that deserves the great love we have to give. If anything, this is a lesson to never take them for granted and love them with all we have no matter how much it hurts when they leave us, whether too soon or after a good, long life.
