I used Embark (embarkvet.com)  to find out  what Juno is.  And opted for the extra genetic testing given the myriad of health issues Vonnie, and Tara both had.   Easy to do, and they put effort into trying to find 'relatives' of your pet.  In fact, 2 years after rescuing Juno we were contacted via Embark messaging & determined Juno's brother lives about 50 miles from us.  We plan on getting them together next month for a birthday party.
