Wisdom DNA Panel
Mixed breed dog DNA testing can be used for many purposes other than 'just knowing'. Determining breed can help predict breed-realted genitic diseases, sizes, and can help vets determine proper medical treatments.

For example: did you know that Ivermectin (a drug found in most heartworm preventatives) can be deadly to a collie or a collie mix?  beagles and beagle mixes are prone to epilepsy? often a cesarean section is necessary to deliver with pekingese and pekingese mix mothers?
Now the fun part ...
Reenie, a 7 year old mixed breed, had the Wisdon DNA Panel ran on her.  Can you guess from these photos what breed(s) she is?
