This is Allen and Rally... they come to my agility classes and compete at local trials...
Here's a shot of Allen and John on course (John is the human, LOL)
Here's Allen again just landing from a jump
In my opinion, these little dogs are wonderful and fairly easy to train. The real problem with them is they are NOT neutered, so they are very distracted by smells, etc. If he'd neutered them, they would really excel on course.
Tell your husband, Manchesters CAN do agility :)
