Aside from some issues with Penny and aggression over food (she's being monitored and it's better) everyone is getting along well. The biggest problem we're now facing is all of them going outside and getting out of control with the barking. It usually just takes one of them to start and then the rest join in. Because of this I'm not really able to let them have free access to the yard as they've had in the past and it's been a bit of a pain. The other day it was actually kind of funny because Noonie made it out first and sounded the alarm. In the meantime I had the other two corraled and poor Noonie just stood there looking sad wondering where everybody was at. So, does anyone have any suggestions on how to curb this behavior? I know there are lots of devices/training aids on the market, but up until now I never even thought about it.
