I have a smooth-haired dachshund. I've had it since it was 6 weeks old. It was nice and small (like any other puppy). But then when it got older, it didn't grow tall, it just kept on growing longer and longer. Right now he measures 7 inches tall by 22 inches long. What should I do? Should I take it to have length-reduction surgery? Back surgery? Should I feed it more? It walks/runs funny, too.
