Can one gate work for both a baby and a dog?

Many of the most-reviewed gates in this category are marketed as dual-purpose, and verified-purchase reviewers routinely report using them for both. The key checks across reviewer consensus: narrow vertical bar spacing (around 2.25 inches or less) so small pets and infants can't squeeze through, no horizontal cross-bars a toddler can climb, and a locking mechanism that requires two-step adult operation.
