The organisers of the Crufts international dog show have denied rumours that other dogs have been poisoned at the event.
A three-year-old Irish setter called Jagger died after competing Crufts amid fears he may have been poisoned.
One of the owners of the prize-winning dog said they have lost "our love, family member and best friend to our son".
The co-owner of a prize-winning dog allegedly poisoned at Crufts said the family "can't and won't" another exhibitor at the show was responsible
"I've done this to raise awareness of the heinous crime that took place that resulted in the death of Jagger," Dee Milligan-Bott told reporters outside her Leicestershire home.
"We can't and we won't think this was an act of another exhibitor. If we thought this couldn't go on," she said.
"I ask you all to unite in finding the perpetrator who did this and lets continue to produce and breed our gorgeous dogs who we are all so proud of."
