Boomer is housetrained, leash trained, goes to his crate when told (although he does bark for a little bit when in it - then he settles in). He knows the sit command and gets along with everybody. He is one of those sweet dachshunds that runs up to greet everyone that passes, tail wagging, not a mean bone in his body. The vet said he is 3, but he still has a lot of puppy behavior in him.  He is very playful.
