There’s going to be hell to pay for whoever put out the gopher poison that ended up killing three dogs on a trail in Marin. From the Chron’s latest update:

The reward has grown to more than $31,000 since Tuesday, when the three dogs died after taking a walk on the Alta Trail in the Golden Gate National Recreation Area above Marin City, said Marin Humane Society Capt. Cindy Machado.

Humane Society officials have determined that the dogs — Nick, a 12-year-old Labrador retriever; Stella, a 10-year-old Lab; and Ajax, a 3 1/2-year-old Swiss mountain dog — were poisoned with a strychnine-based gopher bait that was put into “some sort of meat product,” Machado said.

She believes the poisoning was intentional and that the dogs ate it during the Alta Trail hike because it is a fast-acting poison — which could kill a canine within 10 minutes — and the animals fell ill soon after walking on the trail. The families of both dogs — the Labs belonged to one family and the mountain dog another — live in the Oakdale Avenue area of Mill Valley.

Like I said the other day: a triple homicide’s a triple homicide, regardless of whether the victim has floppy ears.
