A WOMAN has claimed she isn’t interested in children - only Chihuahuas - as she splurges more than £7,000 on her dog's birthday party.

Lizzie Lewis, 26, lives in a rented flat in London with her boyfriend, Patrick Lally, and her eight-year-old pooch, Oscar.

Lizzie, who also works as an online model, appears on a new Channel 5 documentary, Britain’s Flashiest Families.

It follows her as she organises Oscar's eighth birthday bash - and has a bum lift.

She told the programme: “He’s my little baby. I don’t want children, I just want Chihuahuas.”

Lizzie, a make-up artist, has revealed Oscar has an extensive wardrobe, which includes matching jumpers, anoraks, a denim singlet and a Burberry-inspired jacket.

She said: “Oscar’s wardrobe is completely amazing.

“I couldn’t tell you how much I’ve spent on it. For me it’s not really about the money.

“If I see something and it looks good on him then, I will get it.”

Patrick added that the dog has “a better wardrobe than I do".

And that's not the only thing Oscar one ups Patrick on - he also eats better than him.

The couple regularly chop up Waitrose chicken for the pooch's teatime bowl.

Lizzie said: “Oscar is the most fussy eater in the whole entire universe. We give him salmon, beef, chicken.

“He’s really fussy with water as well. He does not like the tap water. We mostly just give him bottled water. Honestly he can taste the difference.

“I’m not joking. He’s a total snob. I think Oscar is the flashiest dog in the country.”

The programme follows Lizzie as she takes Patrick – and Oscar – lingerie shopping and then splashes £685 for four bum lifting treatments.

It culminates in the couple throwing a birthday party for Oscar, which they hire a party planner for.

But Patrick, a director family construction company, questions the spiralling cost.

He said: “It’s all been Lizzie’s baby and that’s why we started off at one figure and it just grew and grew and grew.

“I was like 'babe, you keep saying yes to all this stuff, what’s the total cost going to be for this party have you got any idea? ‘No I don’t know’.”

She admitted Patrick had gone “ballistic” at her over the cost.

But Lizzie pressed ahead with the lavish party, spending £7,200 on cakes, personalised bowls, treats, decorations and seating.

There was another reason for the extravagance, Lizzie said, as it was her pooch's birthday without her nan, who had loved Oscar.

She added: “My nan would probably think I was barking mad but that’s my nan and this is me.”

To get Oscar ready for his big day, she took him to the salon where he had a wash, blow-dry and blueberry facial.

And she lavished hundreds on a gift of a sparkly lead with matching harness.

On the big day, held in their back garden, decorations, seating, a sandpit, cakes, food, balloons and a giant billboard detailing Oscar’s likes filled their flat.

One guest said they’d "never been to anything like this", while another called it a "unique experience" and said it was "over the top", but called it "good fun".

But Lizzie adored the day, saying: “It’s just like the cutest ever doggy brunch birthday party that I’ve ever seen in my entire life. It looks so good.”

And in the end Patrick said it was “good value for money”.

Britain’s Flashiest Families airs on Thursday, November 29, on Channel 5 at 10pm.
