Daniel asks…

When does the human brain stop rewiring?

I was just wondering to see if disabled ppl should always have hope that their mental situations will improve or just loose hope altogether after they’re twenty one or so. I’d like to think the brain keeps rewiring and finds new ways to process info, but I could be wrong, maybe the brain does atrophy after a while and stays in it’s own niche, don’t know. Please answer honestly, thanks.

New Niche Finder answers:

In the late 90’s researchers found that the brain is dynamic. Before that they thought that the brain was fully developed at 3 and that’s the brain you had until you died. But they found that new brain cells are constantly being made and being connected to eachother. So, when does the brain stop ‘rewiring’, really, never.

That does not mean that the brain continually grows but it actually shrinks as you age. After you reach age 30 the brain shrinks about 0.25% in mass each year. Again there is another caveat, smaller brains don’t necessarily mean weaker brains.

Albert Einsteins brain weighed 1,230 grams (2.71 lbs), significantly less then the human average of 1,300g to 1,400g (3 lbs). Also 30% of 80 year-olds perform as well as young adults on cognitive tests.

Donald asks…

Dogs being used for their intended purpose?

So as most of us know depending on the breed, most dogs these days AREN’T being used for their original purpose or even a variation of it.

WARNING: There is pig squealing so if you are even remotely squeamish this probably isn’t for you.

So for the Dane lovers on here at least, if you haven’t seen the show already I give you Discovery’s Hogs Gone Wild

http://www.youtube.com/watch?v=L_3ya1b2NjM Riddick running a hog down into the water and sticking with it

http://www.youtube.com/watch?v=g6u5YptU3mE For the Wolfhound/Deerhound owners and lovers – wolfgang

And now for questions

1. Does it make you feel good that there are breeders even if they are “few” and owner still using certain breeds(Danes wolfhound etc) to hunt and so forth?

2. For those who’s breeds have stopped being used for their original purpose and have yet to find a new niche what would you like to see your breeding doing for work that exemplifies what your breed is all about?

3. (just for chuckles) anyone with a dog breed that has been/is used for hog hunting(danes, wolfhounds, deerhounds, dogos, apbts, etc) would you ever; assuming your dog was all geared up and had the drive for it, seen your dog on the hunt?
ETA: apparently I hurt some wittle baby’s feelings with the truth. And no my mother was the baddest witch to the left side of the mississippi.
Borderline: Oh yeah possible injuries aside the amount of pork off one hog makes the carnivore in me drool

Wyr: Very smart dog. Better the ear than a snout armed with 2inch or more tusks. i’ve seen what those things can do. not pretty and its a pain trying to stitch a dog up on the hunt.

Watching season one has me wanting to go visit the cousins and tag along for a hunt – for the action and of course the free food. Good day they manage 2-3 hogs when they go out and that covers 4 households plus extra. Besides I need a reason to try out this recipe I found for wild boar ragout

BQ: Not to leave out the rodent hunters any longer : How many of you have had your yorkie, JRT, Doxie etc bring home the fruit of their hard labor?
Bordeline: More like walking food vaccums. Other than the two I know up here in Maine the last fit beagles I have seen were the ones my aunt in texas had. 7 plus one active bulldog. Didn’t hunt but boy could they tear up the ground roaming her 3 acre home.
Borderline: No and No TDs from me. That was directed to some child’s answer that has since been deleted.
Greek: Now you now is “cruel and mean” to make dogs work for their kibble and even worse to make them hunt down other innocent animals. *gags* I agree to the fullest. I wish I knew someone hunting with Danes/Wolfhounds/Deerhounds. In person is much better than video. Meh guess when I am anywhere near Tx again with the BF we can go hunting with L3 – owners of the dog in the first vid – they do guided dog hunts 2 danes and 5 Wolfhound/Deerhound mixes.
EEK No DSR that wasn’t directed at you I mean.

Borderline: Yeah the dog cam is a bit much, but hey whatever works. The show def shows how worse off Hawaii is. Mainland the damn things can spread out, there? No chance and those bastards are messing with coffee plantations. No and just NO.

And maybe he’s running a protection racket on the rabbits. Probably figures he’s not gonna get any stew so why should he save you some money and gas.

Cassie: People are strange and disconnected from nature.

New Niche Finder answers:

My breed, the WORKING, NON SHOW Malinois is still being bred for a purpose and it works it, daily.
This is a touchy subject for me because I am a huge believer in having all working dogs work, however, that is no longer the case. Even though some breeders still breed working animals, the vast majority do not. They breed for show/pets and are killing these breeds.

Yes, it does make me feel good to see these dogs you posted work and being able to do what they were meant to do and do it well, even though I don’t eat red meat.
Now if we can get more of these breeders in various breeds to do this, produce working animals, I will be happy as a pig in shit.

John asks…

Breeding dogs for “modern” activities?

In the void created by technology, many breeds of dogs no longer perform their original function. Some have mentioned recently that many breeds have found a new niche in “modern” activities — agility, obedience trials, therapy work, flyball, dock diving, etc.

Do you think it is acceptable to breed dogs to excel at these modern activities, despite the fact that they may have nothing to do with the dog’s original function?

Example 1: Breeding a line of “agility” Border Collies, or “obedience” Belgian Tervuren.

Example 2: Crossing Border Collies and Border Terriers to get a “better” Flyball dog.

Example 3: Breeding two Labradors with excellent Guide Dog potential, even if they are not structurally sound.

Example 4: Breeding Dachshunds who win Weenie Dog Races, or Chinese Cresteds in order to get your next “World’s Ugliest Dog” winner.

Is there a line to be drawn here, somewhere? Or is all of this okay, since the dogs are performing a function?

New Niche Finder answers:

First, I would want the breeder to explain to be why the breed’s original characteristics are unsuited for the task?

Example 1:

To do agility, you need a dog that is smart and fast (among other things) – sounds like a border collie to me.

To do obedience, you need a dog that is smart, very handler-focused – Tervs fit that bill pretty well.

Example 2: – why? Flybayy – you need fast, ball-focused dogs – both those breeds fit the bill. The team jumps at the jump height of the shortest member – so why try to make a bigger border terrier?

Example 3: Form follows function. Always, forever, and in everything!! A fantastic guide dog isn’t worth shit if it can’t walk due to hip dysplasia

Example 4: You can’t breed winners. You breed the best dogs you have, and assess the pups for potential. Then you start the hard work of maximizing that potential.

So – no. Until someone can tell me the valid reason an original breed cannot fit in their new “niche”. And especially – since the majority of these activities (not all, but the majority), were devised by humans so they can have “fun” with their dog.
