Yes I'm serious. I have a 13 year old black lab mutt that I love. Her arthritis has been very bad the past year. I feed her the best diet as far as I know. Wellness brand senior mix, which is loaded with supplements and definitely high quality.
If she could drop 20 lbs she would walk a whole lot better. T3 seems fairly safe. I'm not sure how long she has left, but she is very happy and I'm just looking to increase her quality of life for the remainder of it.
Can any experts/veterans that have a science background comment on this? I need to do more research, but I imagine dogs have a thyroid gland and it secretes the same hormone.
