Hi and Welcome to BW!
About peanut butter, if I can add, only use the 100% natural peanut butter, it is a bit more liquid it doesn't have the added oil that keeps it together. I use 1/2 a teaspoon in a kong mixed with kibble and freeze it. Gazou loves it!
Very cute picture by the way, hope to hear some stories soon and do take lots of picture, like others will tell you time flies by!!
