Five days prior to admission, vomiting 4-5 times a day and appetite is very poor. For the past 48 hours, dog has been very depressed. Dog has been 15-20% overweight for the past 2 years. Dog is well vaccinated and receives monthly heartworm preventative. Diet is premium dry dog food and table food. 2 years ago, another veterinarian tested thyroid function and it is reported as normal. The dog tested positive for anti-T4 and anti-T3 antibodies but was negative for anti-thyroglobulin antibodies.
	Physical Examination: T. 103.5F, HR 70, RR rapid and shallow, MM are brick red, and CRT is <2.0 seconds. The pulse is thready. Dog is depressed and 10-12% dehydrated. Ausculatation reveals a grade III holosystolic murmur with PMI at 4th intercostal space at costochondral junction. The abdomen is distended and the dog grunts when the abdomen is palpated. The vulva is enlarged and no vaginal discharge is noted. Rectal palpation produces dark black, soft feces. There are tiny red spots on the abdominal skin and vulvar mucosa. The peripheral lymph nodes are normal.
	Diagnostic Plan: Using the POVMR format, identify the problems and formulate a diagnostic plan for this case.
