Fluctuation of Earth's magnetic field and its influence on dogs

Fluctuation of Earth's magnetic field and its influence on dogs Kateřina Beránková The aim of the bachelor thesis was monitoring and documenting the orientation selected breeds of dogs when feeding, depending on fluctuation of the Earth's magnetic field. The theoretical part of this thesis deals with a summary of information about one of the three selected breeds of dogs (deutscher boxer), that was just like the rest of breeds used as a model animal for the practical part. In the next part is introduced magnetoreception, therefore, the ability of animals to perceive the Earth's magnetic field and its hypothetical models of functioning. There is also described magnetic orientation and its other forms which are magnetic map, magnetic compass and magnetic alignment, which is spontaneous orientation of the body axis of the animal in certain direction, for example, in the North-South axis by influence of the Earth's magnetic field. The practical part of the thesis mainly deals with exploring the influence of the Earth's magnetic field on the orientation of the head and of the body axis, when dogs are feeding. Selected breeds of dogs were Deutscher boxer, Bernese mountain dog, Chodsky dog and hybrid of Labrador retriever and Siberian husky. Statistical analysis showed North-South direction preference only in the case of the breed Chodsky dog. For other breeds of dogs, East-West orientation was dominated
