awwww, I think Jake would agree that this little guy would be just perfect as the new head of security. Actually, when I looked at your post..it looks as if Jake is in your avatar, overlooking the pup and I truly believe that's the way it will be. MY opinion is Jake is your canine angel.
Jake will never be replaced. Our hearts just expand to take in to accept another furbaby. He's adorable and I think the decision is already made. When does he get to come home?
Hugs and prayers!
