Canine Health Check - Genetic Health and Disease Screening Test for Dogs - Predict, Treat, and Care for your Pet's Medical Problems The Canine HealthCheck is a screen of more than 150 genes that cause diseases or traits in dogs. It is easily collected in the comfort of your home - no veterinarian required. A 30 second swab of your dog's cheek is sent to our laboratory where we screen the DNA to discover its genetic health status. Inside you will find 2 swabs, instructions and a prepaid USPS label and mailer. This is NOT a breed identification test.
