Good morning! Bill, a friend of mine is in a band that plays at Honk Festival sometimes!
Allison, to follow up on last week's thread, I hate to say it, but your assistant is right to be afraid for her job. And if she's incompetent at it, then IMO you should let her go. It sucks, but you need someone you can count on to do a good job. If you want to help her out personally you could help her find a new job doing something else.
We took Carter in to the vet Friday to check on his issues since we needed a refill of his anxiety medication anyway. The vet was very positive and encouraged by the way he saw Carter interacting with the kids (we had to bring them along), and he said Carter's new separation anxiety issue where he tears up boxes if we go for a walk without him is actually a good sign because it's a much more treatable form of anxiety and it means he's comfortable enough with having everyone in the house to start to get upset about them being gone. At this point his issue is mostly just being really annoying a lot of the time (barking/whining/getting underfoot, that kind of thing).
In any case we got an additional prescription of basically doggie valium to give him as needed while we work on the separation anxiety. We have him one of them this morning when a storm was starting up and he started freaking out (problem because when he gets anxious and very underfoot, he accidentally knocks the kids over) and then once the storm passed DH took the girls outside and Carter was much calmer than usual.
On the other hand, yesterday C decided she wanted to grab his feet while I was occupied with A, and he hates having his feet touched and she wasn't minding me when I told her not to. Sigh. (She just got barked at on her third grab, it was fine.)
Really he's been very good with them lately though. He lets them pet him and grab his tail, and he just walks away when he's had enough -- sometimes they follow him, but that's on us to stop, not his problem. They like to offer him tennis balls and toys and sometimes he takes them from the kids' hands very carefully. I tried having A give Carter a treat the other day but she was afraid to.

I kind of think the fact that they walk and act more like humans now helps their relationship with him, so maybe if they also help feed him he will like them even better.
We still keep him behind a gate when the kids are eating, and he's pretty good about it but also sometimes decides to just constantly bark the whole time he's back there. Giving him treats when we put him behind the gate was a bust because he'd only be quiet if he was getting treats constantly -- it actually made him worse about the barking because he started barking for treats.
In any case I think we are going to go ahead and try to travel for the holidays. Our previous pet sitter doesn't do overnights anymore but she will do 3x/day vacation visits, and the vet seemed to think Carter would be okay with that, perhaps with some extra medication the first few days to ease him into it.
