Natalie Dormer "constantly apologises" for her dog's behaviour.
The 'Game of Thrones' actress is devoted to her puppy Indy but worries the pooch is overly affectionate towards strangers.
Asked when she was last embarrassed, she told Grazia magazine: "Whenever Indy isn't behaving. She can be overly affectionate with people, so I'm constantly apologising to people about her sniffing them or jumping on them."
The 34-year-old actress is currently splashing out huge sums of money on getting the dog trained so she can take her to work with her.
She said: "My biggest extravagance is my puppy; she's named after Indiana Jones. She's a Rhodesian ridgeback.
"She's being trained within an inch of her life because I want her to come on set in the future, so I'm spending a lot on training classes."
Meanwhile, the 'Hunger Games: Mockingjay - Part 1' actress insists she isn't as strong as people always assume her to be and has moments of feeling "pathetic".
She said: "The biggest misconception is that I don't have moments of vulnerability and weakness because I tend to play strong women. But I can cry and feel pathetic and like I want to give up, just like any other person."
Despite suffering a number of setbacks in her career, Natalie hasn't let them get her down and has learned to persevere.
She said: "My biggest life lesson is perseverance. If you get knocked down eight times, get up nine.
"It took me 12 years to get where I am, but anything worth fighting for can take time. It's a marathon not a sprint."
