OK, that's fair enough. Remember to lag the pipes well or you'll be
wasting money.

Probably not, if you wash the dog and then don't use it for a few hours it
will be cold even if lagged.
If you frequently use the tap then lagging will save money.

Lagging may stop it freezing, but may not.
If there is a longish run outside then plastic pipe doesn't burst when it
freezes but the taps might.
