First to arrive in this episode is collie Mac. With a phobia of big open spaces, this dog is definitely suffering with a case of the collywobbles and won't even get out of the car when his owner Claire takes him to the park. Next into the practice is Natalie, with her pungent pug, Carla. Carla's 'bottom burps' are so smelly that she's been banned from friends' houses. And the last case of the day is a petulant parrot called Barney. Barney's aggressive behaviour towards the family and particularly against youngest sister Summer means he is ruling this roost. Can the experts help?
