Middlesex means the land of the Middle Saxons, and the name turns up as Middelseaxan in a record from 704. It was an administrative county for a very long time, until 1965, when it was absorbed into Greater London.
The name hasn’t gone anywhere in people’s heads, or in search boxes. If you’re in Harrow, Ealing, Hounslow or Hillingdon, you may find the help you need under either label, so this page shows which AboutDogs guides sit under Middlesex and sends you to our Greater London page for the rest. Keep both open.

Walking near the Welsh Harp
The Welsh Harp, or Brent Reservoir, was completed in 1834 and 1835 to keep the Grand Junction Canal’s Paddington branch supplied with water, and it has been a Site of Special Scientific Interest since 1950. That makes it a place for close control and a careful eye on signs, because wildlife is the point of the site. Our Middlesex swimming guide above covers other spots if your dog loves water.
A supplement option for daily loops
Much Middlesex walking is the daily loop round a local park. If you’re weighing up a supplement, Calmshops has Calmdogs probiotic chews to look at. Run it past your vet first.
