Should not be.
What is in your squid.conf (without comments) please.

setting up the cache to do dns resolution and not to use the clients

I have the squid cache do the dns lookup and use that rather than

'it' referring to what?
When using a proxy clients rarely ever do DNS lookups themselves.

Oh. You can:
enable the DNS section of debug logging in cache.log and watch the DNS
lookups in progress.
tcpdump/wireshark the data stream and see who is doing lookup for
domains.
log on the local networks DNS server to see who is looking up what when.
(in recent squid) look in squids access.log to see where its requesting
traffic from for any given request.
use 'squidclient mgr:ipcache" to see what squid has resolved each
domain to.
