Uterine horn intussusception in immediate post-partum in a Pomeranian Spitz dog

A 2-year-old Pomeranian-Spitz dog (5.8 kg) was admitted with symptoms of uterine prolapse and lethargy 1 day after whelping three puppies. The prolapsed uterus was corrected, but the next day, prolapse reoccurred. To fix the cervix to the abdominal wall, the dog underwent a surgery operation where intussusception in the left horn of the uterus was found. Ovariohysterectomy was performed as the treatment of choice. The diagnosis of intussusception is challenging, and exploratory laparotomy is the reliable diagnostic approach. Although uterine intussusception is rare, it should be one of the important considerations in dogs within the post-partum period.
