The said in a tribute, posted on the social media pages for Tilley Farm, Sarah's sanctuary for rescued horses, ponies and donkeys.: "We are so sorry to have to share the news that our extraordinary, kind and talented mother, Sarah, passed away recently. It is immensely shocking to us all and came with very little warning. No words could ever express all that she encompassed, or begin to describe the crater her absence has left.

'We know how profoundly she has impacted the lives of so many, and we couldn't be more proud of the legacy she is leaving behind. We only wish she'd had more time to share her knowledge and brilliance with us, and the world.

"Our grief knows no bounds, nor did the reaches of her incredibly unique and irreplaceable spirit."

The Battersea Cats and Dogs Home in London - which Sarah had worked with over the years - paid tribute in a statement, saying: "'We're truly sorry to lose our beloved friend and Ambassador Sarah Fisher and send our deepest sympathies to Sarah's partner Anthony, her daughters, and her family and friends.

"Sarah, alongside her partner Anthony Head, gave so much to our charity, fostering dogs, using her canine expertise to train our staff and volunteers, and contributing in so many ways to make a real difference in animal welfare.

"She will be dearly missed by all of us at Battersea."

Sarah was also patron of Holly Hedge Animal Sanctuary in Somerset.

Their founder Pauline Leeson said in a statement: "Sarah was an advocate for all animals and was always a voice for those dear souls who have no voice.

"She will be a huge loss to the animal kingdom she worked so tirelessly for, helping so very many animals of all species to find their way to cope and be happy in this changing world.

"We at Holly Hedge are so proud to have known Sarah. Her memory will live on in all the good work and positive change she has made to their lives.

"Our hearts go out to Anthony, Emily, Daisy and family."
