Illustration for the book ´El perro´, by Ediciones Veterinary dissemination consultation (Castellón). The idea was to illustrate the tendency of each dog breed to develop different pathologies depending on their size, shape, hair, etc. For example, in the case of Basset Hound, hound created by man for hunting, with very short and strong legs, and very powerful nose, they tend to develop infections in the ears or the reproductive system because they are so close to the ground.
