What are the causes and effects of this thyroid gland on my dog? My vet told me that is the reason she isnot getting fat no matter how much she eats.

As per Dr. Elbeze, hyperthyroidism is quite rare in dogs. The main cause of this in dogs is thyroid carcinoma or there is a lab error. I would make sure to have the thyroid level tested again and confirmed and have a free t4 rather than a total t4 tested. If Soska has hyperthyroidism, I would recommend speaking with a veterinary oncologist about further testing and treatment.

Hi there. Yes, I agree that Soska needs some blood testing but I would also recommend some fecal testing and a test to check to see if the pancreas is producing enough digestive enzymes (here is a link about this issue). http://www.petmd.com/dog/conditions/digestive/c_multi_exocrine_pancreatic_insufficiency There are many reasons as to why a dog may eat well but not gain weight. You are going to have to have some testing done to figure it out. Hope this helps. Best wishes!
