He was panting, rapidly and weakly, and didn't know what was going on around him. It looked like an insecticide poison, but they had no idea where he could have gotten it. But we started treating him for it. I also consulted with the toxicologist at University of Idaho, Dr. Talcott. She suggested taking X-rays, to make sure Gaitor hadn't swallowed some pennies.
Some pennies contain zinc, which is extremely toxic.
There were no pennies on the X-rays, but there were some little spots that looked like they could be shotgun pellets. Medication to make Gaitor vomit produced some pieces of a rubber ball. Rubber spikes on the ball were the spots on the X-rays. I didn't recognize the other plastic pieces in the mess, but the owner did. That's a cattle ear tag.
