I have a question. On Saturday morning I took Buck for his yearly shots. The vet was concerned that Buck is still continuing to grow at the age of 4. He is still a very solid lean looking dog but is now 130 pounds. He is 28 3/4 inches to the shoulders so quite tall. Anyway, she decided to do a Thyroid blood test. Is there anything I should be aware of depending on the outcome of the test, i.e: DO's and DON'Ts?
