Hi Pat We are not as lucky as you being able to get testing at such a low rate.
Does this mean the dog has to be at least one year for your program? We test a lot earlier than one year. It is possible to see MVD as early as 7 months in our experience. If you are going to show a dog and hopefully use it in your breeding program, it makes a lot of sense to get your dogs done early. It is no guarantee that the dog will ultimately be clear but it does help.
