Hi Lizzy, thanks for asking.

Welp, I think I made a discovery.
The week that was SO BAD, and after that, I noticed things weren't so bad...
hmmmm.......
I put 2 and 2 together, and realized the
real reason things were so bad was
because my hubby was home for a week. He had the week off work.
That was when everything went totally insane. But I didn't have a clue as to why.
But this week, he went back to work, and I noticed all the dogs were VERY calm....
Everyone got along, everyone took nice naps, no fighting, no "arguements".
Remarkably peaceful household. I've been watching everything very closely.
So now I am thinking we had a horrible case of jealousy.
Buddy is madly in love with my hubby, and he couldn't cope with my hubby
giving Jack attention. Buddy thinks he "owns" my hubby, and so he was
distraught and confused as to why HE wasn't the center of attention, as he
has always been.
And at the same time, Jack was jealous of Buddy, trying to dominate Buddy,
trying to be "the top dog".
Hubby went back to work 7-6-09, last Monday, and I immediately noticed
how calm things were. But when hubby got home that night, things began to
get ruff again, so I told my hubby my thoughts about everything.
I told him, when the dogs began to get aggressive, "this doesn't happen when you aren't here".
So, sure enough, there is a pattern to this.
I don't understand it completely, but enough to know it CAN be solved without
having to rehome Jack.
That is my thoughts as of today.

Hopefully, I can keep Jack.
He and Buddy have been playing nicely, with hardly any problems.
So I really think it was because my hubby was home for a solid week,
something the dogs weren't used to, and something that caused them to
go haywire. Keeping my fingers crossed about this.
