It was in 1932 that he acquired his first Scottish Terrier but found that the dog was very aggressive. Then in 1934, he became interested in the Sealyham Terrier and thought that by crossing the two breeds, he would be able to develop a good hunting terrier that could work in a pack and “go to ground” when needed being small enough to do so. He crossed the two breeds in 1949 to create the first Cesky which he named Adam Lovu Zdar. Horak recorded all the bloodlines he used in his breeding programme over the following years. However, his dog was shot by a hunter a year later by mistake which set Horak’s breeding programme back considerably, but he continued using a Scottish Terrier called Scotch Rose. Six puppies were produced which were to be the foundation stock for the Cesky Terrier.
