Ultrasound is used as a tool to evaluate your pets internal organ such as their liver, kidneys, bladder, gall bladder and heart.  It is not a sole means of diagnosis but is another tool we use to gain additional information if pets have vague symptoms or abnormal blood work.  

To have an ultrasound performed, pets will need to be shaved either on their abdomen or on both sides of their chest under their elbows depending on which cavity we are evaluating.  Most pets do not need to be sedated but very large dogs, panting dogs and fractious cats may need something to allow a full evaluation.
