Gringo is a medium sized dog (63 cms.), very good muscles (39 kgs. – without fat) – he is a real Power dog. Gringo has just passed his first international test (IPO 3) with 290 points of 300, grade: excellent. He also passed the Running dog trial test with 199 points of 200, grade: excellent. I train Dogs now for many years, but Gringo is really an exceptional dog. He is very courageous, strong fighting instinct, is learning very fast, has a lot of joy in training and is still a very friendly and sociable dog.
