Because Snickers and Petunia were not getting along really well with Rosco and Penny yet and because they were not accustomed to ramps, we needed a few practice runs. First everyone had to simply go up and down the ramp individually. Then they had to stay in the car while the next pig entered until they were all in. Finally we took them all for a few short drives to be sure they would be okay. “How would you get 4 pigs to do this so well”, you ask. A little sprinkle treats go a long way.
