One of my dogs howl/bark when I return.
I am never away for more than three hours at a time, and during which they have access to the garden via the dog flap.
They play and sleep when I am away and there is little/no barking (I keep an eye on them via CCTV)
But when I return, they recognise the sound of my car and they run to the gate and start barking.
I tell them to be quiet but they keep barking till I get inside the house and they run inside via the dog flap.
The barking starts off the dogs across the road as it can be loud.
I am having to rush myself and run inside.
How do I get them to be quiet?
