Hodnocení přežitelnosti spermií ovčáckých plemen psů
 Sobotková, Lenka
Topic of this work was evaluation of spermatozoa of shepherd dog breeds, where we took a closer look on evaluation of dog ejaculate quality from FCI I. group. In this work the basic methods of ejaculate evaluation were mentioned as well as special evaluation methods, with focus on durability tests for needs of fresh semen insemination with use of special solutions. For our purposes were chosen 7 dogs, 5 of them were Czechoslo-vakian shepherd of one owner and 2 dogs were German shepherd breed of the second owner. For the best elimination of environmental influences on results these dogs were masturbated in home environment. As solutions we used UHT milk, dry milk, Androhep, Androstar, stallion solution and distilled water. We used standard mathematical-statistic methods for data evaluation.

Testing traits Saarloos wolfdog and Czechoslovakian wolfdog
 Peterová, Dalia ; Fiala Šebková, Naděžda (advisor) ; Jana, Jana (referee)
This thesis is about cognitive behavior of dogs and wolves. It focuses on breeds of Czechoslovakian Wolfdog and Saarlooswolfdog, resulting from crossbreeding of a dog and a wolf. The thesis describes their natural behavior and abilities to cooperate and communicate with humans. The thesis repeats series of behavioral experiments performed on dogs and wolfs described by Ádám Miklósi in his study from 2003 "A Simple Reason for a Big Difference: Wolves Do Not Look Back at Humans, but Dogs Do". We were interested to know how these particular crossbreeds would behave in the same model situations, thus we tested them on the Czechoslovakian Wolfdogs and Saarlooswolfdogs. The first study shows whether the subjects are able to locate hidden food indicated by a known gesture of a human experimenter. The second study examines whether the subject, that is not able to solve a similarly looking task by itself, looks at a human for clues. The dog easily learns how to solve a simple task: opening an object to get to food. And it subsequently faces a similar situation, in which, it is impossible for the dog to resolve it by itself. These experiments demonstrate that Czechoslovakian Wolfdog and Saarlooswolfdog are able to collaborate with humans with similar willingness. There is no statistical difference between these two breeds and the two sexes of these animals.
