Genetically if one animal appears twice the animal is considered 'inbred'. BUT the percentage is VERY low. Most breeders ( again talking dogs here but would assume its relatively the same) would call the pedigree a linbreeding, since the inbreeding doesn't occur in the first few generations. The term inbred means : to produce by breeding closely related individuals. So if you had cousins in the pedigree it would be inbred. No ifs, ands, or buts.
The term line breeding was brought about by breeders as the general public dislikes hearing the term 'inbred', as in humans its a bad thing.
In dogs I have done father -daughter breedings. Once and then all the off spring was outcrossed. When I breed dogs I go for phenotype ( type to type) more then I do for pedigree breeding. But that's just me. Posted via Mobile Device
