Summary The twelve-year-old mixed breed Shadow is obviously in a terrible state. He is dizzy, ice cold and walks crouched down. Tanja Beilmann brings her dog to Alexandra Erbeldinger's practice in the hope that the vet will quickly find out what is wrong with him. But the patient poses many puzzles for the vet. Blood work, ultrasound and the test for intestinal parasites do not shed any light on the matter. Shadow appears to be healthy. Only a stool sample provides the decisive clue. A dog named Tequila needs a little high: Veterinary assistant Lea Kilian is worried about her English bulldog. The dog, who is only five years old, walks poorly and limps on long walks. Unfortunately, this is not uncommon for the overbred breed. In addition to breathing problems, bulldogs are also prone to various other illnesses. Veterinary doctor Fabian von Manteuffel has to x-ray Tequila to rule out the dreaded hip dysplasia, a malformation of the joints. But Tequila is not a typical representative of her strong and brave species and needs a little buzz for the examination. Stephanie Petersen is visiting unpredictable large animals: Island veterinarian Stephanie Petersen has to go to the cattle pasture to take blood samples from unpredictable large animals. Breeder Matthias Tlke needs annual proof that his Galloways and Limousins are free of the bovine herpes virus, a highly contagious cattle disease. A cow like this weighs up to 800 kilograms, so caution is required. Although the giants are forced to stand for blood samples, it becomes dangerous when Stephanie Petersen has to reach through the gates.
