Colgate-Palmolive 's second-quarter results have shown a decrease in revenue, partly because of declines in its Hill's petfood division, Reuters  report ed. The fall in the share prices wiped out gains from the past two weeks.

Colgate's quarterly profit, however, topped estimates with a 7.5% increase in prices that helped offset the revenue drop. Hill's, which accounts for 14% of Colgate's total sales, increased prices in  2008 and earlier this year to offset higher costs.

Colgate's second-quarter sales dropped by 5.5% to US$3.75 billion, whereas the analysts, on average, expected US$3.78 billion, according to Reuters estimates. The company said it was comfortable with the forecast for the third quarter of the year.
