there arent many.. oops.. hi .. many pines that are going to stay within that width... and if you think they dont drop needles.. good luck with that ...

i would refer you to thuja de groots spire.. i have one.. in the 12 to 15 foot range ... that is about 3 feet wide ... from a one foot plant 10 years ago ... it grows about 18 inches per year ... depending on ground freeze [you need to tell us where you are .. soil type.. etc] ... link below

God i hate yappy little dogs .. kids i can appreciate, and they are rather trainable .. dogs are a nuisance .. and frankly.. just idiots.... lol ... anyway.. i digress ...

frankly.. moving is the best choice.. for a fast resolution ...

and do understand.. that buying big.. will give some instant gratification ... but the plants will take longer to 'establish' and return to normal growth.. it is often said.. that smaller transplants recover and get moving .. faster than very large plants ... so with thuja.. arbs.. i would suggest.. no bigger than 3 to 5 feet to start ... which should also reduce cost ...

you are not going to find these at bigboxstore ... so use the link .. and near the top.. use the FIND A GARDEN CENTER button.. and have some ordered in at the next PROPER PLANTING TIME ... which will be either fall or winter.. depending where you are ...

and when you get to planting.. do write us.. and find out how to do it PROPERLY ... regardless of what plant you end up choosing ...

ps: and perhaps.. coming from the other direction ... and knowing many peeps with pools.. is your pool going to be there forever .. maybe it will be simpler to get rid of it ... lol .. as i understand.. they are much like boats.. the happiest day of your life.. is the day you get it.. and the second happiest day.. is the day you get rid of it.. and that day is often.. happier.. lol ...

Here is a link that might be useful: link

I couldn't recommend anything better than:

Thuja occidentalis 'Wintergreen' aka 'Hetz Wintergreen' aka 'Hetz Pyramidal' (all the same plant, just three different names).

You can get some real nice starter plants online at Evergreen Nursery.

Space them 4 feet apart and you'll have a thick screen with height.

Where are you located? Knowing where you are and what potentially may grow in your area opens up the possibilities a lot.

Arborvitaes are an excellent privacy screen but not at all fast growing - will take years before "starter" plants provide any sort of privacy. Evergreen shrubs are a possibility as is bamboo but need to know where you are to make relevant suggestions.

If you get an arborvitae, do read up on bagworms online. They're a pest that can be a very bad problem if they show up, and you want to identify them early on.
