Comparison website Confused.com is to sponsor The Pet Show at Stoneleigh Park, Warwickshire, on July 20-21.
Confused.com will occupy a stand in The Kennels section of the show, where it will provide attendees with advice on how to use its service to find the best available insurance for their pets.
Show director Ian Sear said: "Having Confused.com exhibit at the event was great for The Pet Show, but we are really delighted that they have decided to increase their presence here and become title sponsors.
"They bring with them a brand trusted by consumers and a real willingness to engage with pet owners who will be visiting the show hoping to get exactly the sort of expert advice they bring to the table."
Kate Rose, Head of Pet Insurance at Confused.com, said: "Our relationship with The Pet Show so far has been excellent and we are thrilled and delighted to take that relationship on one stage further.
"We are really excited to attend the show as both title sponsors and exhibitors and look forward to meeting pet owners who want to talk with us about how our service can help them."
The Pet Show claims it will feature more animals, exhibitors and displays than any other multi-pet event in the UK.
The 21,000 square metre exhibition space is set to be home to over 20,000 pet lovers.
