I do not know the dog, Fighter. According to my records his sire, Hasko, is 10 years old and has not produced anything of note. Hasko, himself, competed once at an FCI regionals where he failed both tracking and obedience. He is linebred on the T litter bösen Nachbarschaft and by an exceptional dog, Nick Heiligenbösch. He shows a bit of weakness in his mother's lines, but for the most part he has a good pedigree.
The dam of Fighter has produced one notable offspring and had a littermate that competed. Her pedigree is not the strongest, but not bad either. She was probably a flashy obedience dog.
That is all I have.
