Sarah Ferguson says she went to a dog whisperer after becoming concerned over the late Queen's "grieving" corgis.
The Duchess of York adopted the beloved pooches, Sandy and Muick, following the former monarch's death last year.
But she became worried about their behaviour after noticing their tails had stopped wagging.
The 63-year-old told ITV's Loose Women: "I went to a dog whisperer and said, 'Now tell me about grief'. And he said, 'Just at night just make sure they have their own space'.
"Yeah, so I do. Because I think they were grieving - their little tails went down. And I wanted to make them have waggy tails."
During the interview, Fergie also revealed that she isn't expecting an invite to King Charles' Coronation next month.
The duchess - who shares daughters Princess Eugenie and Princess Beatrice with Prince Andrew - said she has other plans for the big day, and isn't sure she will be invited to attend the ceremony in person.
Instead, she wants to take the late Queen's corgis with her to a nearby nursing home and plans to celebrate with them, putting bunting up and turning it into a big party.
She previously said of the pets: "I really love when I'm with them actually, I really think about HM and I just think about the value system she supported in this country and how the nation mourns her.
"But yet how exciting we move on to a new monarch and the Coronation, and I think so important for the whole country to unite and uphold the value system that for 72 years the monarch gave us all."
Speaking on how she still misses the former monarch, Fergie added: "Her Majesty was an incredible head of state, an incredible mother-in-law and an incredible friend.
"For me to be able to call her that was the greatest honour in my life. I used to have to pinch myself when I was sitting with her and asking her advice.
"Her door always remained open to me and we saw a lot of each other right up to the end, for which I will always be grateful. I miss her more than words can express."
Fergie has spoken of her support for the King and Camilla, who will be dropping the Consort part of her title when the Coronation takes place - something which Sarah is glad to see happen.
She told OK! Magazine: "I have known both the King and the Queen Consort since I was a child.
"I think if you look at the King's track record in areas like the environment, where he was decades ahead of his time, and the Prince's Trust, it's clear what an extraordinary man he is and how fortunate we are to have him on the throne."
She added: "I also admire the way the Queen Consort has worked tirelessly in areas like literacy and domestic violence."
