What an awful take. Of course some people incorrectly breed dogs in ways that cause serious health problems but most Dachshunds dont fall into that category of mutant dogs I had 2 growing up, one lived 13 years and the other lived 17 years no issues with their backs because we didn’t allow them to jump onto high things. Some dogs require special attention to help them live happy and healthily, so do most animals including people. It’s not like they are pugs who noses are now so flat they can’t breathe properly, these are just sausage dogs and they have always been long.
