A landscape gardener's dog led to him driving while more than three times over the limit.
Wayne Clegg called for a taxi after drinking but the driver would not let his dog travel with him.
Clegg, 30, of Meadow Close, Clifton, near Kirkham, pleaded guilty to driving with excess alcohol.
He was sentenced to 12 months supervision, banned from driving for three years and ordered to pay £60 costs by Blackpool magistrates.
Pam Smith, prosecuting, said on September 21 at 12.30am police saw Clegg in a Ford Transit van at traffic lights on Mains Lane, Singleton.
The van set off, mounted the kerb and drove along a grass verge for 20 metres.
Clegg stopped when police put on their vehicle's blue light.
When asked how much he had to drink he replied "enough".
A breath test showed 118 micrograms of alcohol in his body – 35 is the limit.
He had a previous drink-drive conviction from 2005.
Mitch Sarangi, defending, said: "He would have had to remain with the dog overnight or leave the dog alone in the van."
