When breeding one wishes to improve on what the parents are. you would expect to have some champions in a five generation pedigree, as you would expect the breeder to use quality dogs.
That said it is pointless using a Champion dog if he does not complement your bitch. sometimes there are doigs with a good track record that don't quite make their titles. In the UK it is very hard to make up a champion, and if only they were used there would be no breeding stock.
Also a dog may be used who is very promising and is likely to get it's title with time, and the same for the bitches.
A pedigree that had no title holders at all would make me think that the dogs were just bred for sale wit6hout any thought as to quality of the animals being mated.
I would do a Google search on some of the names in the pedigree, and you should if any of them have won any places at Championship shows, get the details up.
