CANTON -- You’ve heard of drug-sniffing dogs and you may have heard of bomb-sniffing dogs, but have you ever heard of a frog-sniffing dog?

Nature Up North is hosting a wildlife detector dog demonstration on Tuesday, Sept. 24 from 5:30-6:30 p.m. featuring Newt, a young Labrador retriever, who learning to find and alert to Eastern Spadefoot Toads.

The event will be held at Wachtmeister Field Station, County Route 27.

These frogs are the rarest amphibian in New England, listed as a threatened species in Massachusetts, and are particularly difficult to find, said a press release from Nature Up North. They spend most of their time underground and only come out on rainy nights – not the best time for two-legged volunteers to be searching the woods, the press release said.

When he is full grown, Newt’s job will be to travel to Cape Cod with SLU student/handler Hannah Duffy and find the frogs. Once the pair has located the burrows of this elusive amphibian, Audubon Society biologists can gently dig up the frogs to collect data needed for conservation of the species, said the press release.

Newt, Duffy, and SLU Biologist Kris Hoffmann will host the discussion about frogs, dogs, and conservation on Sept. 24.

Newt will mingle with the crowd and demonstrate his talents.

The event is free and all ages welcome.
