2020 season

Dow was drafted by Richmond with the club's first pick and the 21st selection overall in the 2019 AFL national draft.^[18]

Following a full pre-season training period, Dow made his first appearance for Richmond in the club's first 2020 pre-season series match against Collingwood in Wangaratta.^[19][20] He impressed head coach Damien Hardwick with five disposals in just one quarter of match play and earned another selection in the club's second and final match of the pre-season.^[21][22] Dow went unselected when the season began later that month and was also unable to play at reserves level after the VFL season was cancelled due to safety concerns as a result of the rapid progression of the COVID-19 pandemic into Australia.^[23] At AFL level, just one round of matches was played of the reduced 17-round season before the imposition of state border restrictions saw the season suspended for an indefinite hiatus.^{[24][25][26][27][28]} Dow starred in an unofficial scratch match against Collingwood's reserves when the season resumed in June following an 11-week hiatus, the first of a series of unorthodox reserves games played that season in place of the official VFL competition.^[29][30] He continued to play scratch matches through the rest of June, but missed one match in early-July due to a stomach illness.^[31][32] Dow traveled with the main playing group when the club was relocated to the Gold Coast in response to a virus outbreak in Melbourne in July, and continued to play reserves grade matches during that time.^[33] He was named a non-playing AFL emergency for the first time in round 8 and again in each of rounds 12 and 13, before being named to make an AFL debut in round 14's match against West Coast at Metricon Stadium on the Gold Coast.^{[34][35][36][37][38]} He recorded 12 disposals and three clearances in the match, which was played like all matches that year with playing time reduced by one fifth, owing to the pandemic-induced fixture changes that resulted in multiple games played with short breaks.^[39][40][41] After a quieter follow up performance the following week, Dow was dropped back to reserves level ahead of the club's round 17 match against Geelong.^[42][43] He remained there for the balance of the season and through the month of October, while his senior teammates won the club its 13th AFL premiership.^[44][45][46] Dow finished his debut season having played two AFL matches and earned the Cosgrove–Jenkins Award as Richmond's best first year player.^[47]

2021 season

Dow completed a full pre-season training period ahead of the 2021 season, impressing in an intraclub match and participating as part of an extended playing list in a practice match against Melbourne in February.^[48][49][50] He missed out on AFL selection early in the season, but played reserves grade football with one VFL practice match in mid-March before undergoing surgery to remove his appendix later that month.^[51][52][53] Dow returned to fitness to in early May, featuring at VFL-level as an inside midfielder including as one of his side's best players with 31 disposals and six inside-50s in a win over the Greater Western Sydney reserves in mid-May.^[54][55][56] He was named an AFL-level emergency in each of the next two weeks, but ultimately went until round 16 to earn his first AFL match of the year, picked to play against the Gold Coast following a performance at reserves level that included 23 disposals, eight clearances and a goal.^{[57][58][59][60][61][62]}

Dow was delisted by Richmond at the end of the 2025 AFL season after 45 matches over six seasons.^[63]
