I am so sorry for your loss. I know that those words offer little comfort. I don't have any kit suggestions for you, but there's a site that focuses on quotes for scrapbookers and he had quite a bit for dogs including the death of a pet. Here's the link to the animal section;

I hope that you are able to scrap your memories and always hold them close to your heart. HUGS to you.
