Luke wasn't rough. He simply rolled with Dollar's struggles and stopped it from writhing around, which was easy to do with his Quick Reflex and ample Dexterity.
Touching Dollar, he realized that its entire body was shaking, or more precisely, twitching.
The dog's breathing and heart rate had also sped up. There was nothing but panic and pain in its eyes. It subconsciously looked at Selina, as if asking its young master for help.
Frowning, Luke picked the dog up with one hand and threw Selina on his back with the other. "Let's get to the ranch. There's a vet at my grandpa's place."
With that, he dashed to the ranch like the wind.
They reached the ranch in five minutes.
A farmhand gave them a strange look. "Huh, Luke and Selina? What… are you doing?"
Luke ran past him even as he spoke.
Luke's voice rang out. "Bart, where's Ferreira? Dollar's sick."
The farmhand replied quickly, "In the cowshed."
