This live dog lab will have 6 tables for ultrasound instruction. Our goal is to have 1 instructor per table and groups of 4 participants at each table (24 DVM participants). Each participant will scan for 4.5 minutes before rotating. After all 4 participants have scanned at a table (i.e. every 18 minutes), groups will rotate to the next table. An example timeline for the morning session is in table 1 below. The afternoon session would be the same, it would just start at 1:30 pm. The topics for each table are listed below in table 2. Each table would need someone to monitor the dog, ultrasound gel, alcohol, an ultrasound scanner, and 5 stools. Dogs should be clipped in advance. The haircut over the abdomen should extend from about the 10th intercostal space caudally to the inguinal region and about 2/3 of the way up the side of the abdomen on the left and right. We will need at least male intact dog and 1 intact female dog for the morning session and the same for the afternoon session.
