I am new to this site; I came here in hopes of finding some help. I have a 5 year old Great Dane cross that came from the pets for life foundation 2 years ago. Riley-bear did have some issues when he came to us but with training and love most of them have been worked out. We brought home a 1 year old Great Dane last night, and things are not going so well. Any insight as to what we can do to make the transition easy??
