Thousands of stray dogs are reported to local authorities every year, with the Dogs Trust estimating that almost 50,000 are dealt with every 12 months. But the charity also says there is a huge variation in the way local authorities respond to stray dogs - with some saying they handled none at all in a year while others tackled hundreds.
The Government says that if you find a stray dog and know who it belongs to, you have to return it, with a widget on the Government website helping you find a local dog warden.
The situation is the same in Wales - where local authorities will help. Carmarthenshire County Council says: "Our dog wardens are responsible for seizing stray dogs, often in response to calls from members of the public or when on active patrol of the county. Stray dogs will be kennelled and inspected by a vet if required."
