He seems to be a very popular stud in Germany and Czech Republic/Slovakia. However, when I look at his accomplishments, it seems he has not participated in LGA, BSP, etc. Same is the case with some others like Bomber vom Wolfsheim, Drago vom Patriot, etc. However, their number of breedings is just insane (source: winsis-cat).
What is the reason behind this? What do they bring to the table? Is it their pedigree or their structure, temperament, etc.?
Could some one please explain? Thank you.
