Sumo is a very independent 2-year-old Shiba. I never had to potty train him. Since I got him (8 weeks old), he associated grass with potty. He is phenomenal with kids and humans in general. He is super healthy and has an active lifestyle. Sumo is very well-behaved, loves to go for car rides, and loves outside. He is very quiet and does not do the Shiba scream lol.
