I sure wish I could keep frogs in my yard, they are so "good" for the micro-ecology. Sadly, _-IF-_ I have a snake or frog or lizard in my yard, it has a VERY short life expectancy.
In addition to the retired Narcotics Interdiction Beagle, I've got a Jack Russell who is a retired USDA / US Customs and Border Protection "Detector Dog". She spent 7 years on Guam and was trained to sniff out and "prosecute" various things, snakes and reptiles was her specialty ( she's also trained in narcotics detection.) I've watched her go up and launch off the top of a 10 foot chain-link fence just to kill a frog!
