A staff member at the dogs home where at least 40 animals were killed after a fire has told Sky News it was "like something out of a horror film".
Colin Ballance, the liaison officer for Manchester Dogs' Home, said the scene was "horrendous" with flames up to 20 feet in the air when he arrived on Thursday night.
Mr Ballance managed to rescue two dogs from the building complex before thick black smoke stopped him.
"You could hear them screaming but the thing was, you couldn't do anything," he said.

Mr Ballance said: "It was unbearable, it was like something out of a horror film. Something I don't want to remember if you know what I mean, but I will never forget it."
A 15-year-old boy has been arrested on suspicion of arson following the blaze.
Detective Chief Inspector Neil Jones, from Greater Manchester Police, said the youth from the local area was detained within an hour of the fire being reported just after 7pm.
Residents reported hearing "dogs yelping" as the fire spread through the buildings.
There were reports of people risking their lives by running into the burning building to save animals.
Mr Ballance says he will never forget what happenedAt least 43 dogs were confirmed to have died, with "numerous" other animals having to be treated for injuries, police said.
Part of the roof of the single-storey kennels collapsed and 30 firefighters battled the flames, said Greater Manchester Fire and Rescue Service station commander Paul Duggan.
Outrage and shock at the blaze resulted in several fundraising campaigns being launched which have raised hundreds of thousands of pounds for the home.
The Manchester Evening News newspaper had originally aimed to raise £5,000 but this has now soared to over £800,000.
On its Twitter page, Manchester Dogs' Home said: "Words are not enough. Thank you everyone, you have touched our hearts and surrounded us with love and we are truly grateful.

Anna Stansfield, manager of the home's sister facility, Cheshire Dogs' Home, described the fire as "soul destroying".
She said all the 150 dogs rescued by the fire service would be transferred to its site in Grappenhall, Warrington.
The blaze provoked an angry response on social media, but police warned people not to "take matters into their own hands".
The home has cared for more than one million dogs since it was established in 1893. It is said to care for more than 7,000 stray and unwanted dogs each year.
Police are asking for people with donations of bedding, food or bowls to take them to Central Park Police Station between 11.30am and 2.30pm.
Reverend Mike McGurk from the nearby Christ Church says they have been receiving donations of dog food and blankets throughout the night.
"People have come from York, Derby and even Stevenage to donate supplies. It's been incredible how strong the support is and how generous people have been," he told Sky News.
