Video library
Welcome to the BSAVA Video Library. This page gathers together all the clinical videos that are published alongside our manual chapters and Companion articles. If you have access to the source content you will be able to play the video from this page, as long as you are logged in. If you do not have access, clicking on the video title will take you to the source article or chapter. You can either use a library pass, or buy the chapter or article, to gain access to all the videos and the full text of that chapter or article. Please note that library passes cannot be used on Companion articles - BSAVA members already have access to Companion. Alternatively you can buy the entire book to gain access to all the videos in that book. You can use the filters on the left to focus on your topics of interest and you can also search the site and filter by content type=video. Please contact us with any feedback or suggestions.

Normal pain perception in a dog.
The palpebral is elicited by touching the medial or lateral canthus of the eye and observing for closure of the eyelids. The afferent arm of this reflex is mediated by the trigeminal nerve (CN V; facial stimulation), whilst the efferent arm is mediated by the facial nerve (CN VII; closure of the eyelids). (See page 12 in the Manual)
Lack of palpebral reflex on the right-hand side of the face in a West Highland White Terrier following middle ear surgery. (See pages 216 and 230 in the Manual)
Pancreatic biopsy in a cat using 5 mm punch biopsy forceps.
This clip shows a dog with hypermetria in the right thoracic and pelvic limbs with no evidence of paresis. A subtle left-sided head tilt is visible. This combination of clinical signs is suggestive of a central vestibular syndrome on the right side, causing a paradoxical head tilt. A mass lesion was found in the right cerebellar-medullary angle. (See page 15 in the Manual)
Spinal pain – Grade 1.
A Chinook during a dyskinesia episode. Note the alert mentation along with the dystonic and athetotic-like movements. There appears to be mild dystonia in the face, as well as a mild dystonic head tremor. Towards the end of the clip, one pelvic limb appears to show ballism-type repetitive movements. Within the Chinook breed, episodes appear to show relatively consistent phenomenology. (Courtesy of R Packer) (See page 249 in the Manual)
Paroxysmal dyskinesias are episodic movement disorders in which abnormal movements are present only during attacks. Some breeds appear over-represented. Although increasingly being recognized, these are often poorly characterized in veteinary literature and are commonly mistaken for an epileptic seizure or even pre-syncopal episodes.

The right thoracic limb monoparesis is caused by a partial brachial plexus avulsion. The dog is able to flex the elbow and advance the affected limb forward. (See page 337 in the Manual)
Passing instruments around the caudal edge of the falciform fat.
PROM is an effective way to preserve joint range of motion in patients that have reduced limb use due to either neurological or orthopaedic conditions. It should be noted that because it is a passive exercise, it does not enhance muscle mass. When performing PROM, the patient should be relaxed and lying comfortably in lateral recumbency. The affected limb(s) should be gently held and each joint isolated and slowly taken through the full comfortable range of motion. This exercise should be repeated 15–20 times and as frequently as every 4 hours, depending on how often the patient moves their joints independently. (See page 490 in the Manual)
The patellar reflex is performed with the animal placed lateral recumbency and the stifle slightly flexed. The tested limb is supported by placing one hand under the thigh. The reflex is elicited by hitting the patellar ligament with a reflex hammer and observing an extension of the stifle joint (reflex contraction of the quadriceps femoris muscle). This reflex evaluates the integrity of spinal cord segments L4–L6 and associated nerve roots, as well as the femoral nerve. (See page 21 in the Manual)
This clip shows a right parasternal long-axis four-chamber view in a dog with a PDA. Although the PDA itself is not visible, there is left ventricular dilatation. Contractility remains within normal limits.
Patent ductus arteriosus is one of the most common congenital cardiac abnormalities in the dog. A small proportion of these congenital abnormalities are associated with pulmonary hypertension and reversal of the direction of blood from the pulmonic to the systemic circulation (right-to-left shunting PDA). This causes cyanosis, secondary polycythaemia, exercise intolerance, intermittent hindlimb weakness, syncope and even hyperviscosity and seizures.
The probe is placed over the oesophagus, cranial to the heart base, allowing a detailed view of the PDA (at the top of the screen). Colour flow Doppler is used to demonstrate the turbulent blood flow shunting from the PDA into the main pulmonary artery.
This clip, using colour flow Doppler, demonstrates turbulent blood flow (with a mosaic of colours) shunting from the aorta into the pulmonary artery through the PDA.
Collapse episode in the dog showing normal consciousness and seemingly normal forelimb function, with normal respiratory rate and effort.
Echocardiogram showing right atrial and ventricular enlargement, with concentric hypertrophy of the right ventricular free wall (right parasternal long-axis view).
Echocardiogram shows interventricular septum appears subjectively flattened (parasternal short-axis view at the level of the mitral valve).
