The last three puppies we got were girls because Max our dachshund has an attitude problem with males. Not sure if this behavior is his natural personality or because of his health problems. But, he has seemed to tolerate all the girls fairly well. He's doing the best with the new dachshund, Muffin which really surprises both Dick and I. She adores him and he puts up with her very well when he's awake. When he's asleep and anyone wakes him (including Dick or I) he does NOT take it well. Cranky boy!
