Marcus is our new puppy. He is half Cane Corso and half Boerboel. He had a rough patch and got parvo at four months. Never had a dog get parvo before, it was touch and go for a while. Nursed him through and he is back to full strength. He is a quick learner so far. Wants to please. Is somewhat timid after the parvo, wants to be close to us and does not like being outside (we have two fenced acres for our dogs) nearly as much now unless we are out with him.
