Gopher poison worries

I need to tell about some of the dangers of using poison underground to kill gophers.
In the spring time it was our practice to culivate the fields of alfalfa which envigorated the alfalfa growth it seemed and also killed the first weed which sprouted. For lots of reasons better left alon at this time.
I would use what we called "Spring toothed Harrow. It would sink into the ground a few insches or more and the spring action would loosen the soil and dig out the first sprouted weeds and seeds. Also it would level the gpoher hills down so it was easier and better for mowing.
The sprig tines would sink deep enough to uncover dead gopher bodies which now are shriveled and dried out. The bodies were killed by the pooson and in all cases the gopher had a pouch fup of the BB sized poisoned millet. The millet was treated so that it wouldn't sprout I think.
One morning when I was busy cultivting my little dog name Taffy was out following the tractor. She usually rode the tractor with me and we were inseperable. When I saw a mouse running, I'd point at it and she would jump off and catch the mouse.
This morning was different. When she was following the tractor I noticed that she was walking erratically--really strange. I jumped to the right conclusion--that she was really chewing on a dead gopher and ingested some of the millet poison. I stopped the tractor and picked her up and she went into a convulsion right in my arms--she was a total charlie horse--stiff. I put the tractor in high gear and when I ran into the hous ei yelled to call the VET quick. He said, "Bring her down we'll put her to sleep" --Holy cow --I was losing a very fvorite pet. I rushed down to the vet who was waiting and I though that it was the end. He did put her to sleep because strychnine causes such conviulsions and causes the heart beat to go wild. It was in the nick of time. He gave her a shot in the leg and she went limp--out like a light. I still though that my dog was dead. The Vet told me to go homw and come back in the morning. I did just tha. I was greeted by the gog which was almost normal but when I touched her it was like an electric shock. The Vet aid, "Don;t do that or I'll keep her another night". I wondered why, and he told me what the effects of stychnine was. She would still be touchy for days. And she was.
There was anothe time like this. but I'll save it for another paragraph.
