Several of my clients have recently tested their dogs DNA using The Wisdom Panel. As a trainer I do see the personality and behavioral effects that different breed types have on dogs although these personality and behavioral effects do not always follow the breed 100% of the time. For example I have seen aggressive golden retrievers, labs who hate water, and border collies who are couch potatoes. However, since our visual accuracy is only correct 25% of the time when determining breeds in mixed breed dogs this test can be of great help to both owners and trainers. They can answer questions such as: Why does my dog nip at my kids? Why does my dog prefer to be with humans than other dogs? Why is my dog still bouncing off the ceiling after a 2 hour walk? Why does my dog insist on bringing me gophers, squirrels, etc.?
These tests also help in determining if dog owners need to have their dogs tested for MDR1 or Multi-Drug Resistance 1. MRD1 is a genetic mutation. Some dogs, particularly herding breeds or mixed-breed dogs with herding breed ancestry have a mutation in the MDR1 gene that makes them defective in their ability to limit the absorption and distribution of many drugs. These dogs are also slower to eliminate drugs from the body that are transported by P-glycoprotein. As a result, dogs with the MDR1-mutation may have severe adverse reactions to some common drugs, so it is important to test your dog and share your results with your veterinarian.
In the end I think if taken with a grain of salt The Wisdom Panel is worth the money and should be considered by owners of mixed breed dogs. You will build a better understanding of your dog and form a deeper connection.
