I do think she is part beagle, b/c of the way her personality is; very hyper/playful, attention hog, affectionate, & also you cannot let her out of your sight otherwise she is either chewing something up or dragging our rugs accross the house. you can def hear beagle or hound dog in her bark as well. but my fiance & i think that she might have some german shepherd in her b/c of how protective she is when certain people are in our house. she goes nuts when my brother walks in the door, but is loving towards my nephew. it is really strange, it's like she feels intimidated around "some" people. she also has white paws with spots of tan & a white tip on her tail. i seen rat terriers before, but they always had "wire" fur coats. peyton's coat is very soft. thanks for your help.
