I just adopted a long haired dachshund and she was spayed today. She is EXTREMELY lethargic, barely lifting her head, will drink water, but won't eat even the most tempting things. She is going to the bathroom all right but her little nose is burning to the touch and chapped. Should I be concerned or is this normal after spaying? Since she is new to me, I don't know how she is normally.
Optional Information: Age: 3; Female; Breed: mini dachshund
