My Dachshund Is Acting Lethargic, Seems Sad, And Is Trembling. This Has Been For Over A Day Now. He Has Lost Any Interest In Playing Is Not All Active Like Usual. What Might The Problem Be?

Any time your pet is lethargic or acting out of the ordinary you should call or take them to their vet. He could have any number of illnesses or it could be nothing, but you really shouldn't risk your pets health on a guess!
