I have A Shetland Sheepdog-Mini Australian shepherd mix I would like to know the fallowing?

adult coats usually come in from 4-6 months deppending also lots of training she seems to have some dominance issues especailly with food walks and a job will help her as well to get ride of extra energy which can help with the barking but u can also try to use noises to make her stop baking training must be consistant though also both breeds are hearding breeds so she may begin hearding the other pets and kids hense find a job for her puppy pads out do ur business out side the sent may make her just want to play with it also lots of excercise is important lots of socialization as well with people and other dogs get her in training though and get the food aggression niped in the befor she thinks she can do that to u or ur kid she thinks shes the boss not u or the other dogs and u have to establish a pack mantality or she will make her own u and ur kid are the leaders and all other pets are the fallowers and she is not in charge of any of the other dogs a trainer will help u best with this. watch the dog whisper as well that may help some too
