Welcome to the site! I have the best tip ever for new Dachshund owners...
Housetraining a Doxie can be an ordeal, they are very stubborn, so training can also be quite a task! But it's best to keep things positive, force training a little Doxie doesn't work, use LOTS of treats... but make it part of (his/her) daily rations... the last thing you want is an overweight Dachshund! They are prone to back problems, so the extra weight is killer.
Make rewards immediate. When housetraining, go outside with the puppy, on a leash is preferable, say "go potty" or whatever you want to use, then stand and ignore the puppy until he goes... if he doesn't, after about 5 min, bring him righ back inside and straight into his crate... try again in a bit. When he does go, treat IMMEDIATELY. say "Yes" in a happy, but not loud voice when he's going, then treat as soon as he's finished. then inside for playtime. Don't wait 'till you come in for a treat, as soon you'll have a puppy going outside then right back in for his treat... They're smart little boogers, and will work the system if they can! LOL
last tip from me... ENJOY your little pup... they are alot of fun... if you have a sense of humor... and you will need one... they are very busy little critters! LOL
I am 4 days away from getting my second little deaf and sight impaired double dapple mini shorthair... I am sooo excited!
