Cairo is really timid, shy and calm. he is currently 9.5 months old. Do you think his temperament will change as he gets older, like would he become more assertive, confident and tough? Only reason i ask is because he is scared of the littlest things, including pigeons, he actually ran the other way when a pigeon landed on our window sill LOL it was so funny!!! Ive heard people say that dogs change as they get older but what do you guys think?
