My adorable Yorkie just turned 6 months. She was super shy & quiet when we first got her approx. 2 1/2 months ago, played with and got along great with our cat, my parents cat & dogs (teacup Min-Pin & her sister). We have taken her on trips & out as much as possible to get her socially acclimated, and hiking in a front pack with no problems. She was so sweet & good with people that we were considering her being a therapy dog once she was done with all of her shots & was fixed. Bur lately she has gotten very protective & growls/barks like crazy if any of the animals get near her toys or bed, if they get near us if we're eating, or at people that walk by while hiking - though not if we're out walking around town. I have no idea why she is suddenly doing this or how to stop it, any advice would be appreciated.
