Are adders protected? what do you do when you have them in your garden?

next door told us he saw an adder crawl under our garden shed a few days ago, he knows what they look like. The shed is at the bottom of a long garden and out of the way. Is it preparing for hibernation and how much danger would pets be in, i.e. dog, cats
