Molesworth Pet Cemetery

It has been quite a while since I posted a photograph of the headstones in the Molesworth Pet Cemetery in Huntingdon. I found another this afternoon and was struck by the statue of a small dog at the top of a column. Then I looked at the angel with raised arm on the left of a nearer grave. On the opposite side of the cross, I can just make out another small dog statue, but cannot make out its name. I have had another look and almost thought I can see two dog heads - siamese twins? There is, however, only one pair of front paws dangling over the front of the name plaque. What do you make of it?

Martian Burial Site?

Here is a photograph of a Dogs Cemetery at Molesworth in Huntingdon. Some of the dogs' names are visible. They include: Jinnie, Fitz, Viper, Joan and Mackie. In the case of the latter, Mackie's large headstone [front, left] bears the following description:
"In Memory of Mackie [Martian Wee MacGregor)
Died in India September 7, 1912
Aged 7 years
Clever and Affectionate, this little Scottie was a great companion and never failing delight to his Mistress who bitterly regrets him.
His place can never be filled"

Why does his headstone bear the word 'Martian?' What does this mean?
