Standard Poodle bloat pedigree. Circles indicate females, squares indicate males. Solid symbols indicate dogs that have bloated. All the affected individuals have additional brothers and/or sisters, not shown, the status of which is unknown.

The first affected dog (at the top) was an AKC Champion and top-producer. His son was exported to Europe and the balance of the pedigree is comprised of Swedish and Finnish poodles.

Though most of the unaffected dogs are related to some degree to the ones that bloated, the bitch indiated with the arrow is Polish and shares no recent ancestry with the others. Though we cannot exclude the possibility that she carries the same recessive allele as the others, we are not forced to suppose this if the trait is dominant.
