hello
i own a car yard and i have a dog on guard there at night,his got his own room with a large dog flap to get in and out,but i was told by a customer it is illegal to have adog on guard,his also my best friend during the day he spends most of his time with me in the office,and sometimes my son takes him home.he gets plenty of exercise,his in top condition.
is it legal to have guard dog on the permises.
                                                           thank you

All guard dogs have to have a handler with them whilst they are on duty, well that is my understanding of the law.

If you are in the UK then your customer is right. It is illegal. Guard dogs have (I believe) to be registered and have (I know) to be supervised AT ALL TIMES.

Regards, John

Under the Guard Dogs Act 1975, the use of a guard dog at any premises except agricultural land or dwelling houses is not permitted unless a handler is present on the premises and controls the dog at all times, and warning notices are displayed at the entrances. If the handler is not present the dog must be secured.
