Thousands of pounds have been raised for the family of a 10-year-old boy who was killed in a dog attack in Caerphilly.
His parents, Emma and John, from Caerphilly, said they were "absolutely heartbroken."
More than £12,000 has been raised to support the family with funeral costs.
In a statement, the family said: "Our lives will never be the same without Jack. This is not something any parent should ever have to be writing. We have so many words we want to say about our beautiful boy, but they do not seem enough.
"We love him more than words can describe. Our boy made us the proudest parents and family on the planet. He was the sweetest of boys.
"We will forever miss his quirky ways and his stories that he would spend so long telling us.
"He's forever in our hearts. Sweet dreams Jack, our perfect boy."
Gwent police confirmed on Friday that an inquest had been opened.
They also said that a 28-year-old woman from Caerphilly had been released on conditional bail and that they'd spoken to two men - a 34-year-old from Mountain Ash and a 19-year-old from Caerphilly.
Although police have not identified the breed of dog involved in the attack, they said that a "thorough procedure" is ongoing.
