How do I keep my puppy safe around electrical cables?

A puppy that has never had access to a dangling cable never learns to chew one, which is far more reliable than trying to train the behavior away after the fact. Cord covers and cable tidies, available cheaply, remove the temptation entirely.

Pet safe bitter tasting sprays applied to unavoidable cable sections can deter some puppies, though results vary between individuals. Treat it as a backup measure alongside physical prevention rather than the main solution.

Home offices and entertainment units tend to have the densest cable clusters in a house, behind a television, a router, or a desk setup, so these rooms deserve the most thorough cord covering and are good candidates for a gate if the cables cannot be fully hidden. A spare bedroom used as a study often gets overlooked simply because it is used less often by people, even though a puppy left briefly unsupervised there faces the same risk.

For a puppy that has already shown interest in chewing cables once, treat that room as off limits without direct supervision for several weeks rather than assuming a single correction has solved it, since a cable that delivered an interesting texture once is often worth another try from a puppy's perspective.

If you are renting or cannot permanently reroute cables, a simple cardboard box with a cable sized hole cut in the side, placed over a power strip or cable cluster, is a cheap, effective temporary barrier that most puppies cannot easily move once weighted down with a book or two on top.
