Texas is a very
energetic, smart and playful German shepherd dog. "He always tries his
best to please me," said his owner Helene Bäckman.
But when Texas was six months old, Helene noticed that he started to behave unusually.
He started to jump and bite the air repeatedly.
"It´s like he sees something. He jumps and when he´s biting, he bites hard," she said.
"You can hear his teeth against each other.
"He can do this for hours and he gets more and more stressed when he´s doing it. He never rests between jumps."
The reason for Texas' unusual
behaviour? Obsessive compulsive disorder (OCD).
OCD is well described in humans and the dog version of the disease presents with similar repetitive
behaviours.
