Zsa Zsa Gabor's dog has died.

The 94-year-old actress - who is bedridden following a string of health problems - was upset when her Shih Tzu, Macho, passed away recently and her husband Prince Frederic von Anhalt revealed it will be impossible for them to replace the pooch because their home is full of nurses looking after Zsa Zsa.

He told nwitimes.com: "The last of my wife's dogs died recently, Macho, her little Shih Tzu.

"A couple years earlier, her other two Shih Tzus, Ruby and Zolan died. We can't have any more dogs around the house because there's so many nurses and help coming and going."

Frederic - who is Zsa Zsa's ninth husband - is currently planning a huge bash for their 25th wedding anniversary and recently took out a huge poster board on Los Angeles' Sunset Boulevard, with an advertisement featuring a picture of the couple on their wedding day from August 14 1986 and a caption reading: "Prince Frederic & Princess Zsa Zsa 25 years and counting."

Explaining Zsa Zsa's reaction, Frederic said: "The Billboard has been up for a week and my wife is very happy.

"Her first words were 'Oscar De La Renta,' because the gown she was wearing in the picture is one she adores."
