Jean Dodds is a saint. Not only has she collected data to support the evaluations she does but she also offers products that benefit breeders at a relatively low cost. She is incredibly responsive to questions. I use Hemopet as often as possible for testing.
I let our vet do the initial testing. Typically its about $40 and they can identify if there is an issue. Then based on severity, you can send out more blood for further tests. I have had 2 dogs tested and put on medication (for being plump and not eating a lot, and no other thyroid symptoms) and they came back low and it was adjusted with a pill.
Love Jean Dodds. Her thyroid test is more comprehensive than what the local vets do, and she is very respectful of your relationship with your vet, knows way more about thyroid than ANYBODY! I just have my vet do the blood for me and I mail it to Jean Dodds……...
