My beautifully behaved 6 month female has gone from being pretty saintly for a pup to unsettled and barking for attention during the day. It was too good to be true! I love her to bits but I'm finding this very difficult and cannot concentrate on my work at home. Is this normal for age? I'm thinking maybe the adolescent hormones kicking in? She sleeps well, eats well, has a good walk morning and afternoon. We play, train etc. She is also happy being left for a couple of hours or so. But when I'm in the house she just wants me!
