My Jolie was like that. She had this thing about the kitchen and wouldn't come in. I think each puppy is different. Her litter mate Jen is the brave bold one. Jolie is more timid with new experiances but once she realizes it's ok, she's all over it/them/there.
Even after being a year old, Jolie is still shy and timid around new places and people. She's not mean or snappy but just needs reasurance and have her confidence built.
Funny thing is, she won't walk through new doorways - weird huh? |
