Do you know anyone with a stock/horse trailer?

They are low to the ground, easy to get into.

I wonder if she might step into the back of one of those to get food and water.

You could tie a lariat rope to the door and yank it shut from in front of the trailer. Might be far enough away so that she would not be skittish getting in the back to eat.

Then you could latch the gate and take her to town.

Just a thought.

I am MAGA.
