Arnold is maturing into a solid dog that captures attention both in and outside the ring with his striking red colour, strong head, movement and flat backline.
Similar to his mother Piper, his energetic, mischievous and confident personality captures the hearts of crowds and his human family.
He showcases his strength and agility at home with his regular routines of balancing himself on a small stool as well as popping up onto dining room chairs to help with homework. He is an amazing family dog.
Arnold is always owner handled by Jeffrey Mitchell.
Arnold achieved his Canadian Champion title before reaching 14 months of age! Prior to his title, he had won Best Baby Puppy in show and multiple Best Puppy in Breed. He's a dog to watch in 2025!
Arnold is one of the ten puppies from the GCH Knatchbull's How Soon is Now (Piper) and CH Knatchbull's King Ragnar (Ragnar) litter born in March 2024.
Arnold enjoys reunions with his dad Ragnar, his mom Piper and his siblings at all breed and specialty shows throughout Ontario and the USA.
