Hi! My friend has a golden cocker spaniel 2 years old.She has been left in kennels before but about 3 weeks ago was left in a different kennel. Since she has been home she has become very introverted when on her regular morning walks.Her tail is between her legs,she cowers at other dogs & if they take an interest in her she becomes snappy (which is very unlike her!) She is also very aware of people & will no longer approach them (she previously was very friendly!) Has anyone had this post-kennel affect on their dog? If so how can we build her confidence again? Thanks Lisa.
