We ran into a friend while walking the dog. One of their dogs had been bitten very recently by a rattlesnake. The anti-venom and overnight monitoring costs $1000... thought you should know.
When I take Jessie out for the night's last visit, I almost always take a flashlight to be sure she doesn't get a surprise. During the day we let her "go" unleashed... she does her biz and heads right back as we watch.
But at night, snakes are active.
