Fireworks are having a "devastating impact" on guide and assistance dogs and their owners, according to Irish Guide Dogs for the Blind.
The charity, which supports those who are vision impaired and the families of children with autism, warns that fireworks can be extremely distressing for all animals, but particularly working dogs.
Ulla Quayle, one of the charity's benefactors, said her guide dog was forced to retire due to increased stress levels caused by fireworks two years ago.
Sage, the dog, "was never the same dog after", her owner said, and was no longer able to fulfil her duties despite help from trainers.
"She was terrified to leave the house which broke all our hearts as she was a much-loved family member."
“She was only four years of age. I should have had another six more wonderful years with this amazing dog."
Sage now lives with a family in Kerry.
CEO of Irish Guide Dogs for the Blind Tim O'Mahony said that situations like Ulla’s are "not uncommon".
"Not only is the impact on the dog heart-breaking but it’s devastating for the owner who must wait to be matched with another dog which can take many months."
"In the meantime, the independence and mobility which they previously enjoyed is hugely curtailed or completely taken away", he said.
"Every Halloween our teams support a number of our Clients whose dogs have been adversely impacted by fireworks.”
