Rosie is 5.mths old now all going good at moment except she barks at slightest noise. Is this just her getting used to different noises ie neighboors coming and going.people just walking by and other dogs barking. I try not to tell her off and just ignore.give her treats when shes quiet. Shes woken me up in the night at times barking and growling. Just wondered if it a norm thing ??
