Smarty and Gretta

Roger Littlejohn owns Smarty (tan) and Sterling Earhart owns Gretta. Gretta's father is a

Dusty/Sally cross. As is Smarty's grandmother, Dummy. Gretta's mother Opal is a granddaughter of Dummy, as is Smarty's father Floyd. I tried to figure out all the ways they are kin but it is too confusing. Anyhow, if they both make good squirrel dogs they were be a great cross.
