So I got rascal (5 months) 6 weeks ago and hes had really bad separation anxiety he barks in his crate and or ex pen for as long as were not home. Hes been getting out of his ex pen and I don't know how (will set up camera soon

) So we tried many things as far as him being alone (tv, radio, Kong with treats yogurt ,peanut butter, bully sticks, training etc.) Nothing has worked. So our next option was getting another friend. We got a girl that is the same age and we will be getting her on Friday. So I'm a little nervous and i do not know what to expect as far as them getting along and him getting better as far as his separation anxiety.
My family thinks I'm crazy because now it will be double trouble..lol
Is there anyone out there that has had a similar experience or any suggestions?
