Hey y’all, I’m at my wits end here.
I have a 9 year old long haired mini dachshund (Darwin) who I’ve had since he was 9 weeks old. A few years ago, after a move to Texas, I noticed him starting to have some minor separation anxiety issues- he’d pace or bark or lick himself till I came home. So since he’d been kennel trained, we started using his kennel with a peanut butter filled Kong to help when we’d leave. We also leave the tv or radio on, so he has voices and sounds. Our other dog is either kenneled or left in the room with Darwin, so he’s not alone in that way either.
For the last year or so though (definitely a relatively new thing), he’s started to pee on himself in his kennel. STINKY pee. A LOT of stinky pee. EVERY time we leave the house. It doesn’t matter if we take him on a long walk or a short walk before kenneling, he seems to somehow save some pee for anxiety (and it’s not just a little dribble, it is a LOT). And it doesn’t matter if we’re gone for five minutes or five hours, it’s always exactly the same. We’ve spent hundreds of dollars trying to find a solution- we’ve tried sprays, oils, toys, “puzzles” for dogs, several variations of the thundershirt or sweaters, I even broke and got the app that lets me FaceTime him and dispense treats- nothing has helped AT ALL. Now I just have an expensive camera that shows me my dog covered in pee.
We even dropped about $350 at the vet getting him tested for anything that could cause him to lose control of his bladder like a uti, cancer, loss of bladder control, etcetera- he’s totally healthy. Just a jerk.

I love my dog so much, he is my furry son! But I’m at my wits end, I don’t even know what to try anymore. I really don’t want to have to leave him outside all day when I go to work, he’s so small and my yard and the wild critters in it can be so big. Please help, I’ve looked all over google and can’t find any more answers so I’m turning to you fellow pet parents- ANYTHING helps, please let me know what you did/would do!
