I have made an appt at my vet for tomorrow morning to get Nakura's thyroid tested. She is very overweight and very lazy. She would eat us out of house and home if she got the chance. For the past couple of years I have put it down to her season and bloating but this year I really can't get the weight off her. She is fed a Light food and eats it happily. She gets walked daily for about an hour and then has as much run of the garden as she wishes - trouble is she doesn't want to. She would rather lie asleep on the sofa. She is also very snarky.
I have absolutely no idea about the thyroid tests and have read on here a few times about different numbers and tests that should be done.
My vet is generally very good but not knowledge on Bs. Can you please let me know what I should be asking to be tested and what levels would be acceptable for a normal B.
