Selective breeding is not the same as transgenic modification. Selective breeding more closely mimics natural evolution, and while there is still a possibility or unintended consequences, that possibility is a lot lower. It's all genetic combinations that could have manifested in the wild, getting genes that already exist in species to activate. With transgenic changes, you're talking about adding genes to species that don't exist in those species. Genes that have no effective pathway to make that move in the wild.
