Prince Andrew gave the Queen two puppies to help her cope with the loss of Prince Philip, it has been claimed.
Her son decided to gift her the dogs when the Duke of Edinburgh's condition worsened, reports suggest.
The family hope the new arrivals have comforted the grieving monarch following the death of her husband nearly two weeks ago.
She turns 95 today and will enjoy a “private low-key" birthday with corgi Muick and dachshund-corgi cross Fergus.
The Sun say the two puppies were given by Prince Andrew, who bought the dogs while his father was ill in hospital last month.
A royal source said: “The Queen did not plan on getting any new dogs as she feared she was getting too old
“But it was Andrew who surprised his mum with two new puppies when she felt down and alone in the Castle after the Duke was taken to hospital.”
Her Majesty is known to have had more than 30 dogs during her lifetime.
The Queen has meanwhile reportedly "made it clear" she is united with Charles and William in the aftermath of Prince Harry and Meghan Markle's bombshell Oprah interview.
It is claimed she was "disappointed" with aspects of the Sussex's tell-all chat to the American star.
Sources told the Mirror's Royal Editor Russell Myers that Harry wrote his father a "deeply personal" note before the service in a bid to ease tensions within the family.
Charles was hoping to see his son after the service but the Duke told him he wasn't sticking around.
An insider told MailOnline: "The Queen has made it clear to senior advisers that she is united with Charles and William, and was disappointed with aspects of Harry and Meghan's interview."
"There is much pain and hurt on both sides, so this reconciliation will take place in baby steps.
"First, they need to decide on some ground rules as to how they conduct business going forward in a way that makes all parties feel safe and protected."
Royal biographer Ingrid Seward said it is unlikely the Queen would want to be involved in any kind of family summit to address the rift, at this stage at least.
