Royal Canin UK and James Wellbeloved both advised their representatives to avoid large events like Crufts “unless it is business critical”.
Alongside the two major sponsors, The Association of Pet Dog Trainers (APDT) also declined to attend the dog show.
In a statement, the club said: “Further to the government COBRA meeting held on Monday 2 March, and following further discussion, the Kennel Club can confirm Crufts 2020 is currently going ahead as planned.
“Public Health England has not advised us to cancel the event. We are looking forward to welcoming our exhibitors and visitors as usual. However, this does remain an evolving situation and we will continue to adhere to the best available advice.”
It added: “We must be guided by the facts and most up-to-date medical information and at the moment, advice from Public Health England has not changed – the most effective thing people can do to protect themselves is make sure that they wash their hands for 20 seconds or more.
“Following the COBRA meeting, the government has said it is “important that people go about their business as usual” for the time being.”
The group said that “enhanced measures” have been put in place in order to protect visitors, exhibitors, clients and staff at the event.
It has encouraged attendees to maintain good hand, respiratory and personal hygiene, and will employ additional signage and bottles of hand sanitiser throughout the event. It is also supplying a hand sanitiser station at each public and dog exhibitor entrance.
In its latest statement, The Kennel Club added: “We continue to monitor the situation with the Department of Health and Defra, and any further updates will be issued on our official social media channels and website.”
