Bueno, tengo un perro que se llama Roco. Hace tres meses lo llevé a pasear a un parque cerca de mi casa. Cuando una señora se acercó con un pastor alemán, Roco se puso muy violento y empezó a ladrar. Intenté contenerlo pero no pude. Es la primera vez que se porta así. Normalmente se porta muy bien. Me avergoncé mucho. Desde entonces no lo llevo al parque.

OK, I have a dog named Roco. Three months ago I took him for a walk in the park near my house. When a lady came up with a German shepherd, Roco all of a sudden got violent and began to bark. I tried to control him but I couldn't. It is the first time that he ever acted this way. Normally he behaves very well. I was really embarressed. Since then I haven't taken him to the park.
