I think the gun dogs have it a little easier, as in general to perform their 'working' role to a basic level isn't too challenging, as long as the trainer is up to task. I.E most of what is required for a gun dog in a basic working test (not a trial), would be to follow commands, find a dummy (or shot bird) by scent and retrieve it. That kind of thing, is something that most dogs should master with a little training, especially if they have a little inclination from their genes.
With regard to terriers. . . . . . I'm sure I will get my head bitten off here (I have a habit of setting myself up for it). But the word 'terrier' originally derives from the latin word 'terra' meaning 'earth'. Terriers, in all forms were created for hunting and dispatching vermin below (and occasionally) above ground. The main quarry being fox, badger, otter and rats in the early days.
Obviously many of the terrier breeds were 'ruined' in terms of work a long long time ago . . . . .thinks like scottys, westies etc, once upon a time, looked very different. However, others have been degraded in recent history.
When I say that they have been degraded etc, I mean both physically and mentally. Now i'm not saying that no pet terriers should exist, and all should be hard core working dogs. And if folk really want to breed for other attributes, that's fine. . . . but it just grates on me, when they start talking about breed standards, good examples of the breed, and try to talk about what the breed is used for etc.
Working borders, beddys, russels, patterdales, lakelands etc look far far different than their show counter parts, and are mentally and emotionally a world away. The problem is, the daft hunting laws have made it difficult to practice what the terriers were originally bred for, and I fear that one day there will be no true, original type, beddys, borders etc left and all we will have will be the show / pet type, which as lovely as they are and as happy as they make their owners. . . . . are a mere shadow of the originals, and it would be a real shame to lose the ties of dogs that gave us those pet types in the first place.
The beddy is a great example, look at the show ones, big, light bones, leggy things, with a really arched 'roached' back, and a silly top knot and light whisky, curly hair. Then look at the working type, which are half the height, stocky, with no top knot and good wiry curly coats, are straight backed, and for the most part spannable (which means you can hold then around the back and chest with your fingers touching). And most of all, those working types have the heart, grit and determination that makes a terrier, what a terrier is.
Now i'm not saying that one is better. . . . well maybe I am. . . . but please don't tell me that the show types are either good examples of the breed, or the original type. . . .. they are not.
Also, all of my working dogs are excellent family and companion dogs, are fit, healthy and mentally sound. And they amaze me all the time with how mentally and physically capable they are.
Oh yer, and I wouldn't expect to pay more than £200 for say a border, who's family lines I can trace back for decades, and who I expect to work hard for me. Whilst I see pet borders who don't need to do much other than be cute. . . . . being sold for £600? Madness.
Like I said, each to their own, and I don't mean to offend anyone, I just feel that its important to give both sides.
