Sao Paulo: World Cup fans are expressing their love of the game in wild ways, wearing patriotic nail polish, dressing up dogs with jerseys and showing their passion under the sheets with Brazil-inspired condoms.

The usual football frenzy fashion is on full display in the South American host country’s streets and stadiums, from the inevitable replica team jerseys to colourful wigs and flag-themed face paint.

But pet owners, fashionistas and love-struck fans have found their own ways to wear their team colors, with Brazil football kits for dogs, designer clothes for women and caipirinha-flavored condoms for couples.

In one well-to-do district here, the MVet pet store sells a yellow, round doggie poop bag dispenser with a football printed in the middle.

But the hottest-selling item is the $14 yellow dog shirt with the number 10 printed on the back. Eighty have sold so far. “It’s cold here now and he looks cute, and we’re in the middle of the Cup,” said Regina Saccarelli, a 34-year-old architect who bought the outfit for her Maltese.

Around the corner, women get discounts to paint their nails in the colours of their favourite team, with Brazil’s yellow, green and blue the most popular.

Local fashion designers have joined the party, making blouses, purses and dresses for women who want to show team spirit without having to wear a football jersey. “Anything goes at the World Cup. If it’s to celebrate, to cheer, it’s worth investing in fun objects,” Paula Acioli, a fashion consultant and professor at Getulio Vargas Foundation University, said. “Nothing is kitsch.”

Love of country has even made it into the bedroom. Since February, DKT International, a US-based non-profit organisation that promotes family planning and HIV prevention, has sold 2.1 million condoms flavoured like caipirinha, Brazil’s famous cocktail.

Sold under the Prudence brand, the condom is yellow with a green tip. The first 850,000 were supposed to last three months but sold out in 15 days. A pack of three sells for $1.40.
