Keep her !! My Chanel pouted for almost 2 months everytime I kissed Cheri - and believe me it was a lonnnnng 2 months for us - but now they are BEST friends - I think when a new puppy comes into their lives they kind of treat them as we would a mosquito - they're pests and they're small -
When you new baby gets a bit bigger I bet they start having a blast together...Keep kissing him telling him what a good boy he is - let him watch you kiss her - then.... KISS him more lol
I bet he comes around....they're so cute I swear they are jealous like little kids are
