My name is Dawkin's!

Our family acquired Dawkins, an Australian Shepherd about 6 years old now, through a previous friend of my husband. This friend used to rent a room out of my husbands house, and when he eventually moved on, he was unable to take Dawkins with him so we have had him ever since. My husband and I are unsure as to Dawkins full life history, because he suffers from anxiety. We believe he is not in the right environment for his breed, as well as maybe experienced some trauma as a puppy. My husband and I had a baby in March, and ever since Dawkins has become more and more anxious, and is protective of my husband and I against the baby. Dawkins has tried harming the baby a few times. So it is safe to say Dawkins is not a family dog by any means, but I think he is misunderstood, and needs to be in a home with someone who can spend the time, attention, knowledge, and energy to care for him!
