This is my rescue pup Kody. Got him a year ago. 
His separation anxiety in the home is barely existent, some barking at first, but never any damage. He hates being alone in confined spaces, so in a crate he totally goes nuts, so we didn’t use it.

Now I’m going through changes (divorce) and am about to move across the country with him in our camper van. He was always a bit more anxious in the van, hyper anxious in a car, but this past week it’s reached a peak. He keeps finding new things to chew up, worst one was the seat belt just yesterday.. 😩
I don’t leave him alone for long at all. Just short grocery runs or when i go take a shower. 
Anything longer and I need a doggy day care but that’s getting expensive fast…

The plan is of course to find a home soon but that can take 2+ months.

I’ve been cycling through calming chews but haven’t found anything yet that makes a difference. Sometimes he is okay actually, it’s just impossible to predict. He was on Clomicalm for a brief period last summer, that made him worse in other regards, so not an option.

Even all of you that don’t travel in a camper.. how do you teach your anxious dog that a grocery store trip is not the end of the world and they don’t chew up your car?? 

Thanks so much for any pointers/tips!
