So much more about Terriers!
From Martha Hoffman.
"I learn so much from Terrierman!
His article pointed out what Iād never thought of:
that the dogs work without visual input when underground. And that explains a lot: why the intense focus on location of sounds has been selected for. I had previously thought it was just as simple as pouncing on a hidden rat.
I used to wonder why terrier type breeds and mixes tested so well for what I term āPositive Sound Reactivityā, which has two features:
1) intense curious and focused FEARLESS reaction to high pitched or unusual sounds.
2) the desire to FIND the source of the sound.
And then I realized that the Terrier breeds were selected to be interested in prey sounds, maybe especially rodent sounds.
Many dogs will do a head-tilt behavior when they are listening to a sound. The head tilt allows triangulation using hearing, to locate the exact position of a prey animal.
But many of these dogs stop there. They donāt have the instinct to go search for the sound.
Which is fine, they will still be excellent alerters, they just need to learn to go to the sound source, and then to lead the partner to the sound.
But the urge to SEARCH for the sound means the dog will train effortlessly as far as the alerting part goes.
Whether the prey-aggression and independent temperament gets in the way of pubic access training, is a possibility.
Jack Russells or other terriers, mixed with more companion-type breeds such as Poodles, were usually more successful as all-around Hearing Dogs that could do well in family, public, and alerting work.
English Field Cockers are tuned in to bird sounds, plus have a search instinct. However, even they are so active and hunt-driven that they are often crossed with Poodles to create good Hearing Dog prospects.
Thanks for filling in that blank in my understanding!
PRESSURE IN THE HOLE
When a really experienced and well-balanced dog goes to ground, they do not rush in full of fire and belligerence, but creep in listening. They are not trying to move anything yet -- they are simply trying to locate, and they are trying to get a sense of how much pressure will be required to move whatever is in the hole.
When the dog does locate and opens up to a bay, he will be using his voice -- and probably his voice alone -- to move the quarry to a bolt or a stop-end of the den pipe. While a young and inexperienced dog may rush in with grabbing teeth (and get the muzzle bites to prove it), an older and more useful dog will know the easier way to get the job done.
The quarry in the hole is not the only thing under pressure, of course -- the dog is too. The pressure felt by the terrier is directly proportional to: 1) the amount of experience it has had underground; 2) the size of the hole it is working, and; 3) the mood (and type) of the animal it is facing.
I think this is the proper ranking of the main pressure-builders within a working terrier.
An experienced dog is comfortable underground and knows enough tricks and ways of working that it is pretty confident that it can get the job done no matter what is found down there. An inexperienced dog, however, is not battling the quarry so much as its own adrenaline and anxiety.
Whether the dog is experienced or not, frustration rises and falls in direct proportion to the size of the hole. Even a confident and experienced dog feels pressure and frustration in a very tight hole where it cannot move forward or backward without substantial struggle.
The quarry itself can exert pressure on a dog, of course. Both a raccoon and a possum can make enough noise that they urge caution to both young dog and new digger alike. Groundhog and fox, on the other hand, are less likely to voice their objections than demonstrate them with slashing teeth.
All of this takes place in the pitch black, of course. While a sheep dog can receive visual cues from the sheep, the terrier must rely solely on sound and scent. And while too much pressure on the sheep may result in the flock moving too fast or breaking in two, too much pressure by the terrier may result in a rip to the muzzle that will take weeks to heal.
At the end of a dig, just as you are breaking into the pipe, is when things often go bad when you are working terriers. Emboldened by the presence of light and reinforcements, a terrier that has used his voice alone up to this point, may decided it can now go in and grab.
An experienced terrier will try to grab his quarry by the cheek or ear, since a groundhog, fox, or raccoon gripped by the side of its head cannot easily move to bite back. Not every dog is smart enough, or lucky enough, to get such a good hold, however, which is why a smart terrierman will generally step in and pull his dog as soon as he can in order to save his terrier unnecessary injury.
Bottom line: As it gains experience, a working dog learns to relax a little more and begins to develop a bag of tricks and techniques it can employ to tackle different situations. In both herding dogs and working terriers, an experienced dog learns to stay attuned to the pressure building up on the other side of the field or pipe. There is a fine line between too much pressure and too little, and the very best dogs walk this shifting line with the grace and skill of a ballet dancer.
