An adorable dog has been filmed howling at the top of his lungs and 'having the time of his life' in the back of a car after he was given anesthetic.

Scout the golden retriever developed a hematoma, which is the collection of clotted blood after an injury to blood vessel walls, forcing him to get surgery.

The 'big and independent' pet's allergies and ear infection caused him to scratch so much that he developed it.

Bleeding or bruising are two symptoms of the hematoma which causes blood to leak in to the surrounding tissue of the blood vessels.

Scout's six feet tall and 150-pound weight meant he was given a high dose of anesthetic and was filmed looking away with the fairies.

In the heartwarming clip, he holds his snout up to the air and lets out a long howl in Wenatchee, Washington.

Seconds later, the cameraman moves closer to the dog and can be heard laughing at Scout's piercing noise.

He is seen lying across the car's trunk and repetitively yelps in the face of the camera.

Scout's howling then becomes deeper and he begins to slow down his calls.

The beloved pet was filmed yelping from the car's trunk. He 'loves to romp and frolic' through the forest and is 'normally a very vocal dog, always talking and grumbling to people' but was given surgery after got a hematoma, which is the collection of clotted blood after an injury to blood vessel walls

He stops and starts his yelping and lets out a growl as the camera gets close to his nose.

Seconds later, he twitches his nose and the person behind the video asks: 'Are you drunk?'

She then adds: 'Not looking so good.'

Meanwhile the golden dog shows a plain expression on his face and then looks away.

Scout 'loves to romp and frolic' through the forest and is 'normally a very vocal dog, always talking and grumbling to people' when he is socialising, according to his owner.
