Birmingham City Council could face a hefty bill for picking up extra stray dogs as police stations plan to close their doors to the animals.
Animal welfare officers, who already collect an average of 84 unwanted dogs each month, could see the figure almost double under proposals due to come into force later this year.
The local authority already spends £2,000 a month collecting dogs, with the number of strays rising to 1,004 in 2005, the highest figure for a decade.
It is believed police stations operating 24 hours a day take in about 50 dogs a month.
Last month one dog was handed in at 3am on Christmas Day.
The council fears it may have to extend its service, which currently operates only during office hours. It is also looking at whether it will have to create kennels to cope with an influx.
The majority of police stations in Birmingham have already stopped taking in dogs, with just three - Stech-ford, Queens Road and Kings Heath - now accepting animals from the public.
Graham Taylor, animal welfare officer for the city council, said changing lifestyles and increased veterinary bills were some of the reasons why there was a rise in strays in the city.
He said the council would have to carry out a review to see how it would fund any changes.
He said: "There is a locking-of-horns between the Local Government Association and others, including police authorities and the Department for Environment, Food and Rural Affairs, as to the financial aspect involved.
"We are not about to instigate a dog recycling bin next to the paper and bottle banks but sometimes we do feel we are running one."
Police stations were due to close stations to stray dogs in March but the move has been postponed while the LGA and other bodies discuss it.
In 2003, 778 dogs were picked up. That figure rose to 967 in 2004, and 1,004 in 2005.
The animals are taken to Birmingham Dogs Home, where some are re-homed. Only a small minority are usually claimed by owners.
