Sports Information Services (SIS) has secured exclusive rights to distribute content from Doncaster and Harlow greyhound racetracks to bookmakers.
The Doncaster and Harlow rights agreement follows the company's recent deals with Kent-based Central Park and Bedfordshire's Henlow greyhound tracks.
SIS also has deals in place with tracks in Monmore, Crayford, Hove and Romford.
"Following our announcement last week of deals with Central Park and Henlow, we are delighted to announce the agreements with Doncaster and Harlow greyhound tracks," SIS product director Paul Witten said.
"This is a demonstration of our ongoing commitment to the UK greyhound industry, and to strengthening our greyhound offer for our customers"
