I currently have two terriers, two running dogs and a pair of black-and-tan kelpies.

Having had working dogs all my life - my first acquired while I was still in nappies - I've done a lot of foxing and rabbitting with dogs along just for company. A bit over 10 years ago, I acquired my first terrier (the shorter of the two in the first pic) She quickly showed me how much game I must have walked past over the years. Running-dogs are a natural progression, partly as many of the foxes that I see are put up while I'm working and the rifle always seems to be behind the seat, unloaded, or 50 yards away when I'm not in the vehicle.

Much of my intentional foxing - as opposed to incidental - is a matter of covering ground and checking out known earths, logs, trees and the rough country that they favour. Both terriers (mother and daughter) are handy den dogs. Not so hard that I have to dig them, both tending to come up to check on me every ten minutes or so.

Usual modus operandi is for the Jacks to harass a fox in its den for a while, and then I take the dogs and sit, somewhere, quietly downwind. Foxes get insecure if they find themselves in a hole where they can be cornered and harassed at close quarters by a dog. They frequently respond to a short period of quiet by bolting for a "safer" refuge..... which gives me the opportunity to either shoot, or put the sight-hounds after them.

The first pic in my previous post is of us waiting as described.

The second is of the chase. (pardon the poor quality) Note the size of the dust-trails raised by my two speed-merchasnts, as opposed to the minimal dust raised by the fox or the slower dogs. Some power going to the ground, there!!

The whippet is a 4yo. Small , even for that breed, and did not grow out as I'd hoped. She's keen, but lacks jaw-power and has difficulty in pulling up a determined fox. I would not work her without other dogs.
The staghound is 1/2 Greyhound, 3/8 Deerhound and 1/8 Whippet. At 25" at the shoulder, Tessa is more than capable of dealing with a fox, yet has a lovely temperament.
