Hogg, who had dismissed Arul Suppiah late on Tuesday, added the wickets of Nick Compton and Marcus Trescothick as Somerset reached 155 for four in reply to Lancashire's first innings total of 292.
Trescothick was looking dangerous after reaching 56 and sharing a third-wicket stand of 101 with Zander De Bruyn, who was out lbw to Simon Kerrigan late in the day.
Lancashire's bowling options were reduced with Sajid Mahmood unable to take the field after suffering a calf strain in hitting a half century on Tuesday.
"I thought we bowled really well as a unit because missing Saj was obviously a blow," said Hogg, who was making his first Championship appearance of the season.
"Glen Chapple bowled as well as anyone and he hasn't got a wicket yet whereas I've got three. But we knew we'd have to bowl a lot of overs with Saj missing, and we are in a decent position."
Steady drizzle had prevented any play before lunch. But Lancashire made the perfect start as they aimed to make up for the lost time, as Hogg dismissed Compton for a duck with his second ball of the day.
The 26-year-old seamer, who had bowled Suppiah with the last delivery on Tuesday evening, made it two wickets in three balls when he had Compton caught behind.
That left Somerset on 14 for two, so it was no surprise when Trescothick accepted the offer of bad light five overs later and a further delay of almost two hours.
When play resumed Trescothick and De Bruyn played sensibly in difficult batting conditions. Trescothick reached his half century from 107 balls with six fours and an upper cut six, surviving one difficult chance during a lively spell from Chapple.
But then Hogg, who bowled an opening spell of 16 overs, switched to the Stretford End and had the former England opener caught behind off the glove.
"I've just said to Chappy that was my best ever wicket, definitely," he added, revealing that his previous favourite was Michael Bevan on his debut against Leicestershire many moons ago. "Trescothick is such a hard player to bowl to."
Three overs later Chapple's decision to turn to Kerrigan paid off immediately when he struck De Bruyn on the boot as he attempted to sweep, and earned an lbw decision.
