Biblical creationism claims that there was one form of life for every category of life (which might mean, say, genus, family, even species, but its hard to know; it wasn't clear, like everything the bible claims).
However, since there is so much genetic difference between species (and even subspecies) of most types of life, there would have to be considerable change in the genome of most species in an extremely short period of time. If I'm not mistaken, this time amount is 4,000 years (the "flood" supposedly happened about 2,000 years after the supposed development of Earth and the universe I think).
However, look then, at the future. If, for example, about .1% (reference below) of the genetic difference between dogs can happen in about 4000 years, then it might only take, say, about 40,000 years for a 1% change in the genome, which is almost the same difference between humans and chimpanzees.
So, if creationists believe that all of life variety happened within about 4,000 years as the bible says, then they would have to accept evolution anyways.
According to this website:
There are 2.5 million single nucleotide polymorphism differences in some pairs of dog breeds.
If so, then since there are probably less than 3 million nucleotides in the dog genome(since humans have 3 million nucleotides in their genome, and I doubt dogs' genomes are as complex as the human genome), then there has to be about .1% difference (1/1000 difference) between some dog breeds.
