Walks and tugging on his rope toy
We got Sam 1 month ago. His previous owner could not keep him after purchasing a condo. Sam was 11 months old, very tall, and weighed 86 pounds. Sam was a mental mess for a couple of weeks, suffering from severe fear aggression, I guess from being uprooted from his home, taken by strangers. The aggression has started to subside significantly after 4 weeks and lots of training, though he does occasionally become aggressive with our 3 year old Labradore and my wife while he is locked in his crate. Outside of the crate he's a big clumsy puppy that thinks he's a lap dog. Sam is replacing a 12 year old Lab mix who died in November. I believe that he was also a lab Corso mix.
Sam is extremely territorial and has a very high prey drive. He constantly patrols his yard and chases all other animals away. Apparently he hates cats. A lot.
