The vet comes Saturday to do a biopsy on a cluster of tumors on his right booty side. I'll bring up insulin resistsnce and other metabolic issues.. I never knew that about TWH's. There are tests right? To determine weather he has those?
I hope the vetting is a positive outcome
Regarding metabolic issues, yes, the vet can draw blood to have the insulin level read.
If the new owners have the extra money to just do a simple blood test instead an entire CBC workup, it will be a lot cheaper. They could easily have it done while the vet is there today.
It would at least give them a baseline for future reference.
Visual indicators can be many things. Because the metabolism is involved, the indicators for my two didn't begin to resemble each other.
A horse does not have to have all of these but having a few of them together is cause for concern:
Hard cresty neck.
Excess fat around the shoulders.
Fat deposits in the "ham" area of the butt.
Dish at the top of the tail dock that won't go away.
The horse is heavy enough that the topline becomes a water vessel.
Extremely puffy sheath (many times looks swollen enough that someone might think the horse has an infection).
Puffiness over and under the eyes.
Mood swings (indicating insulin spikes). They can be anything from wanting to sleep all the time, to very anxious, to becoming nippy.
Laying down way more than is normal.
Losing energy really fast when being ridden.
While most horses will explode with weight gain, others will drop weight rapidly. My senior guy lost 80 lbs in less than six weeks
He's gone from an air fern to me really having to monitor him. He isn't a hard keeper just will lose weight fast if I don't keep an eye on how much rice bran he eats. Last but far from least - founder
. My 11 yr old had sub-clinical laminitis in all four hooves yet my senior horse never has had a laminitic event.
Since insulin resistance and equine metabolic syndrome are considered Type II diabetes in horses, they need to remember he should not be filled up with sugary treats, that include apples and carrots. Carrots are loaded with sugar.
Unless his insulin level comes back really high, he can have the proverbial "apple a day" but he certainly doesn't need to be fed half the bag of anything
You are getting them off to a wonderful start with Duke, both in terms of riding and caregiving --- I hope they stick to it.
Please let us know what the vet says about the lumps.
