Roscoe got his very own birthday crown and feather boa as well as a personalised vegan cake as he turned 11.

His pals all joined in as they wore multi-coloured party hats and all posed for photograph.

However, one guest, a white pomeranian, broke the trend with a glittery gold fedora.

Roscoe also had a set of balloons for him which were placed in the background for the picture.

Posting on his dog’s Instagram account, he wrote: “One time’s for’s the birthday boy’sss 🎂🎉🎈🎁.”

And the dog’s 947k followers loved the snap as they flooded the comment section.

One fan exclaimed: “Omg he got a better birthday party than me.”

A second wrote: “If this ain’t the coolest party.”

A third said: “What a birthday bash.”

A fourth commented: “Okay, this is AMAZING.”

A fifth said: “Pawsome party.”

Another joked: “I cannot fathom how long it took to get this picture perfect.”

The Daily Mail have reported that Roscoe’s party is a “serious” matter for Hamilton.

A source told the outlet: “Roscoe has been with Lewis through thick and thin, and he loves to treat him.

“He takes him everywhere with him and loves to show Roscoe that he is hugely appreciated, it might sound odd to some but to Lewis it is just how it is.”

Hamilton, 38, has written that the bulldog is a vegan like his owner and that he “loves to travel” in his Instagram bio.

Last year, Hamilton and Roscoe enjoyed a movie night and another personalised cake.

He has also taught his best friend how to skateboard.

The Mercedes driver recently revealed his next career move as he founded Almave – a unique non-alcoholic spirit.
