Dogs will be allowed on Brisbane's CityCats and ferries before Christmas, after 86 per cent of people supported the idea in a TransLink survey.

More than 5000 people voted in the month-long survey, which was announced after the idea was raised in a Brisbane City Council committee meeting in August.

Dogs will not be allowed between the peak times of 6am and 8.30am or between 3.30pm and 7pm Monday to Friday.

They will be permitted to travel with their carers outside those times and at any time on weekends.
