Through the course of our puppy enrichment program [1], we used Mad Agility’s [2] puppy agility equipment [3], including the puppy barrel (mini tunnel).
Here’s Willie (Josie x Rusty Fall 2020 [4]) confidently shooting a full size tunnel like a pro. Willie’s mom tells me there was no practice at all. He just knocked it out. Willie is in training to be a SAR dog.
