Does the rope halter and come-a-long rope fit a smaller animal, even a mini?

Does the rope halter work with smaller animals, minis included? Absolutely! There are a couple things I want you to know:

When using the rope halter on a smaller animal, you can adjust the knots to the proper placement and as you do there will be a lot of slack. This may look funny, but the extra slack does not alter the way the halter communicates.
When working with minis, you will want to be on the ground to get the proper leverage and angle for communication. If you try to work standing up, all smaller animals will have a hard time receiving you commands because the angle is not right.
