A woman has shared footage of her two beloved senior dogs cuddled close together, oblivious to the heartbreaking decision their family has already been forced to make.

Whippets Rosie (white) and Bluebell (dark grey/black) have been part of Daisy Smith's life since she was eight years old.

"We got them when they were eight-week-old puppies," Smith, 21, from Bristol in the U.K., told Newsweek. "They are sisters and we got them together."

Smith's childhood is littered with happy memories of Rosie and Bluebell "playing and running on the beach" during family holidays on the coast. "I would take them to the park to run about," she said. "When we were at home they would always look at me when I was eating and want some of my food."

Over the past couple of years, she acknowledges both dogs had "slowed down" but one thing was unchanged: their bond. "They absolutely love each other and always slept together and cuddled," she said.

However, one thing did differentiate the two dogs. Bluebell was struggling with ill health on multiple fronts. "She had dog dementia, arthritis and cystitis," Smith said. "She was going blind, deaf and was very unbalanced."

Though she made it through one last Christmas with the family, earlier this month Smith's father made the gut-wrenching decision to have Bluebell put to sleep. "She was struggling every day, crying at night and her back legs were going," Smith said.

The video Smith shared to her TikTok (daisyysmithh), captures one of their last cuddles together, with both dogs seemingly unaware of what was to come. Or at least that is how it appears. Smith suspects others. "I think they knew something was off, for definite," she said. "I think dogs just know."

There is evidence to suggest dogs mourn the loss of a canine sibling. A 2022 study published in the journal Scientific Reports saw 426 pet owners who had owned at least two dogs and one of them died surveyed on their surviving canine's response.

The results suggested the surviving dog experienced grief-related symptoms such as a loss of appetite, lethargy, fearfulness and trouble sleeping. Bluebell finally crossed the rainbow bridge this week. "I'm shocked, devastated and upset," Smith said. "She was my childhood dog. It's weird knowing that I won't ever see her again."

She said that Rosie "knew straight away" something was wrong and was "yelping" when her father first came back home without Bluebell.

Smith currently feels "upset and lost" but Bluebell will live on in their memories. The plan is to bury her remains at the bottom of their garden as a lasting reminder of her life and role in the family.

Though Smith is heartbroken, she would encourage anyone going through similar situations to reach out on TikTok and watch her videos.

"I want people to relate and share their experience if they have gone through it and tell me their thoughts and feelings and how they cope," she said. "Sadly, this is the harsh reality of when your dog passes and they have a sibling."
