We have a wire hair too. He’s at least 15 but pretty spry. We also have a rescued Smooth Red that’s 18-20 we think. She gets around okay. We had a pack of the little rascals. Thankfully none were assholes. They bark at pretty much everything and sometimes house training is a suggestion. I’ve enjoyed the ones we had. My youngest daughter wanted a Dixie and we got a Smooth Red. She named him Oliver. Ollie was a good boy.
I was bitten on the face by a Dachshund when I was five and my Grandma had a Black and Tan that was an asshole. If someone had told me I’d have a pack of them back then I’d have laughed.
But I guess you’ve got to have some assholeness in a breed originally bred to go into holes after badgers.
