Hi sue66b,

An ultrasound of the abdomen usually does not require sedation. If they are planning on taking a biopsy they may want to sedate your dog.

The reason why eating is usually not recommended before an abdominal ultrasound is because when you or your dog eats, air is introduced into the abdomen and ultrasound waves do not penetrate air. They will get a clearer picture of your dogs abdomen if he doesn’t eat before the procedure.

Good Luck and I hope everything turns out OK!!!
