Small, lively and famously full of personality, the Dachshund (or Sausage Dog) suits apartments and smaller homes well. Dachshunds are prone to serious back problems, so choosing a breeder who health-tests thoroughly matters enormously. This breed can be stubborn, so short daily sessions broken into small, achievable steps work better than infrequent long ones. Nose work games, hiding treats around a room or garden for your dog to sniff out, tap into the Dachshund's strong scenting instincts. Doorbell reactivity is common enough in the breed to be worth tackling directly through desensitization training.
