The dog
“The dog is very warm and he has something common and natural in the behavior of the human being and therefore he feels and understands the human being and loves him and likes to stay with him... And the dog notices the hatred and the anger and the dishonesty in a person, and he often growls against him... But if there is a thief in the house or a person who has the will to steal, then he growls against him and becomes angry and behaves differently towards him than towards another person , and he follows him and checks his smell with his nose... and in this way the thief can be recognized..."
Since Hildegard was able to see the entire creation in her visions, we also find many animals described in her “Physica”.
Bloodletting in animals
“...if a horse, cow or donkey is weak and thin, half a cup of blood should be taken from it, depending on the degree of its fatness or thinness. After bloodletting, you should give him soft food and dry, tender hay to eat. Then the animal should recover for two weeks or a week or four days after the bloodletting until it regains its strength... After three months have elapsed, blood should be taken again from the same animal during the bloodletting in the fourth month and no earlier, unless: There is an acute emergency due to illness... Blood should be taken from a sheep often, but only a little, by phlebotomy, otherwise it will easily become ill with constant air changes. In the case of sheep, bloodletting should be carried out in moist, moderately warm air, because then the harmful juices in them increase. When the air is dry you should refrain from bloodletting because then your juices will increase.”
