"Gizmo came home from the vet's yesterday. He was transferred to Long Meadow on Monday. He was doing better and then took another turn for the worse on Tuesday and needed a blood transfusion. That seemed to jump start him and he improved a lot and is still holding his own. He will go back to the vet for a recheck on Saturday.
It has been a real roller coaster with him. We are all so attached to him that it has been very emotional. We found out he has something called Immune Mediated Thrombocytopenia. They don't know really what causes it - in some cases they believe it is just hereditary. About a third of the dogs recover completely, about a third recover, but have one or more relapses, and about a third don't recover from the first episode. "
So apparently the chewing of wire wasn't the issue. I had never heard of this condition, so I looked it up and found this:
In immune-mediated thrombocytopenia (IMT), the reduction happens because there is increased destruction of platelets by the body's own immune system, at a rate faster than they are produced in the bone marrow. IMT may be secondary to some other process (such as an infection, tumor, or drug reaction) or it may be primary, meaning that no other causative factor can be found. It is more common in certain breeds, suggesting there is an inherited component. IMT may occur by itself or with other conditions. The main problem for dogs affected by IMT is increased bleeding. Your dog may have nosebleeds, bruising on the gums or skin, and/or blood in the stool or urine (seen as a darker than normal color). Your dog may also appear weak or lethargic.
So there we have it. Gizmo is suffering from this condition but fortunately is responding to treatment. Please continue to say a prayer for him.
