@patty and others that reference a responsible breeder: I got my Jessey (my friend dubbed him the Jester because of his loveable zaniness) - who is my second Basenji - from a responsible breeder and he was well socialized by her and then me. I took him to the dog park which he loved at first, but then after many visits, he became scared. He used to walk the neighborhood, but then became scared. Any boom/bang/bounce - he bolts home. My other Basenji was nothing like this. Jessey has his pack of BFF's but is usually snarky to other dogs (typical B!). My point is, it's not always the breeder. Dogs - like humans - can develop "head issues". It has been very frustrating for me having a neurotic dog, but I've come to accept that's him and would never love him any less! The vet gave me Solliquin to try, but I've been hesitant. Anyone out there tried it?
