Dr. Allen is about to perform a colonoscopy on a 10-year-old dog.
She starts this procedure with a rectal.
She is searching for masses and other obstructions.
She wants to make sure the lumen is straight and the anal glands are ready for the endoscope's insertion.
She uses a mixture of air and her finger to push the endoscope into the distal colon.
She decides the patient requires more enema before continuing.

Dr. Allen tries to reach the ileocolic valve.
She does this by continuing to enema and pushing the endoscope further.
She mentions the ileocolic valve can be recognized by its mushroom shape.

She passes the cytology brush into the ileum.
She mentions this area is good to check for Lymphangiectasia suspected in the patient.

Dr. Allen asks the nurse to pull out the instrument which will allow her to use the suction on the endoscope.
She suctions and uses air and manipulation of the scope to go as far into the ileum as possible then takes both cytology samples with a brush and histopathology samples with a biopsy instrument.

p.5
She biopsies the mucosa of the ileum after noting the villi are blunted.
Villi should be long and flowing.
Because there are no large intestinal signs and the colon appears grossly normal, the procedure is ended without taking colonic samples.

Dr. Allen proceeds to show the various functions of the endoscope and how to operate it.
Red is suction. Blue is air/water. There is a photo button.
There is a lock/free position for the tip.
This scope has four motions: up, down, right, and left.
