Wolves and Sheep and Dogs

Hi animal folks,
An intriguing article by sheep producers appeared recently regarding sheepfolk using livestock protection dogs to protect their sheep from reintroduced wolves and grizzlies.  
http://www.sheepusa .org/user_ files/file_ 713.pdf
Having been raised amidst free-ranging wolves and grizzlies and livestock and dogs in Northern Montana next to Glacier Park on the Blackfeet Indian Nation, I observed that certain cultural ethical husbandry principles had emerged through historical time. 
Wolves and Grizzlies have been present since the Ice Age in my home country, where over time many a livestock folk has had aspirations to raise sheep because of the nutritious grass. I am here to report no sheepman succeeds amidst wolves.
Sheep, the longest domesticated herbivore, have become the most human-dependent and reliant. Livestock protection dogs cannot defend sheep against wolves or griz like livestock protection and sheepdogs can rather successfully defend sheep against coyotes. Livestock protection dogs should never be expected to defend sheep from wolves and griz, as the attempted practice is counterproductive for the dogs and sheep. 
Cattle can generally take flight or defend themselves against griz and wolves when given the opportunity to range away from hungry predators, provided the cattle are otherwise appropriately bred and managed. Presently, cattle successfully share habitat with griz and wolf in Montana and Alberta. Indeed, the wild predators thin out some of the lungers and gimpers, but otherwise generally leave the healthy cattle alone. As well, the Rocky Mountain cattle become wolf and griz savvy, and avoid them, giving way and moving on when such predators so much as lift a nose their way.
Sheep, on the other hand, are helpless against wolf and griz, and cannot be successfully or humanely raised near those predators, nor should they attempted to be. In areas where wolves are re-introduced (unlike the Blackfeet country which has always harbored wolves) the livestock folk seem to be slow learners. 
Those pastoral livestock and dog people who have had the pleasure to live with wolves and grizzlies for thousands of years have learned to live with large predators rather harmoniously. From native cultures symbiotic animal/human relationships can be gleaned and appreciated.
Sheep should not be attempted to be grazed where Griz and wolf take up residence as trouble can be counted upon when nutritional protein resources become seasonally limited. 
Aggressive dogs should not be bred or used to attempt to defend sheep from wolves and griz, as they cannot handle wolves or giz, however selectively or aggressively bred. The spiked collars the sheep folk have devised for their dogs make that clear, it seems.
Selection for canine aggression does nothing more than create opportunities for emergency-room doctors, behaviorists and dogtrainers, as has become clear with current human attempts to select dogs for aggression for whatever purpose.
Sheep cannot be grazed with wolves or griz, and should not attempted to be raised amongst such predators. Furthermore, livestock dogs should not be selected for aggression, and should not be utilized to defend sheep against wolves or grizzlies. 
Those are the empirical if not ethical conclusions from the pastoral/wilderness interface in OldMan's country.
Cheers, Sid

Puppy Socialization

Puppy Socialization
In response to a behavioral question about how to pick the pick of the litter and the appropriate socialization of Border Collies with people and livestock, I would like to share my experience. The dog and horse people (the Blackfeet Indians) allowed my current Border Collie, Spek, to stay with his litter until he was 15 or 16 weeks old. I must say the socialization he experienced with the litter on a ranch with cattle proved invaluable. He knows himself, and has turned out to be the best learning, most well-adjusted dog I have yet had the pleasure to partner up with.
At 6 weeks I can't perceive an adequate amount of individual puppy personality to determine future suitability (you'll have to use the black mouth rule then; pick the pup with the most black pigmentation in the oral cavity to insure you get the smartest one). On the other hand, when observing the puppy and bitch socialization through 16 weeks, the personalities of the littermates become quite clear and distinct. That is the time to pick a dog to match your demeanor, when possible, it seems, despite the pressure to choose early.
When advocating adequate socialization of puppies, I think of littermates living and learning together until 16 weeks of age, during which time the litter freely socializes with one another in an adequate environment along with select, knowledgeable dog people and children. The pups watch and eventually help the bitch work cattle and sheep at the gentle hand of their human leaders.
For happy, knowing sheepdogs, I encourage late weaning and a proper and spacious growth environment. I attribute the personality and intelligence benefits to littermate socialization and bitch teaching, along with human/bitch observation, which becomes focused by 10-12 weeks. The pups learn about people by watching their well-trained mother interact with experienced dog people. The bitch does a lot of the pup training.
In my experience, cowdog pups allowed to hang in the litter for 3 to 4 months seem to easily develop willing human partnerships. They get along not only with people, but nearly all other dogs. The most impressive aspect to me is they do not seem to need food as a motivator, and can be trained on a "willing to please" basis, which for me, is not only preferable, but delightful.
Pups weaned and separated at 6-9 weeks appear to me to be the ones that develop the more pressing behavioral issues, I assume in large part because of deprivation from their species at critical psychological developmental and learning stages. With horses we are always always attempting to look at "natural" behavior in feral settings, hoping to apply our knowledge to husbandry and training. With pups, weaning at 16 weeks seems "natural" if one wishes to extrapolate wolf behavior.
Nice thing about living in Montana is that we have both wild wolves and wild horses to observe. We do this atop our horses with our dogs at our side, the domestics watching the wildlife as we watch, and the wildlife in turn observing all of us.
Indeed, there is no dominance.
Regards, Sid

To the True Horsemen of the Racing Game

Here’s to the Jockeys


If only jockeys could speak their mind like trainers. Last year Big Brown’s trainer criticized his jockey for pulling the big horse up with a widely publicized hoof infirmity. This year Woolley, a Chip off the old trainer’s block if there ever was one, felt the need to blame Calvin Borel for misriding Mine That Bird, for moving too early in the third Leg of the Triple Crown.

It seems everyone accepts jockey criticism. The first words out of both of the trainers of the last two losing Belmont favorites, were words of criticism for their riders, yet both trainers failed to properly prepare their horses to partner with their jockeys. As human nature goes in horse racing, both trainers found it in their hearts to shift the blame from themselves to the riders. Sportswriters find little trouble going after jockeys as an easy target, as well. Desormeaux last year, Borel this. Nice.

These athletes who ride thoroughbreds are little, and they are humble. Jockeys know better than to find blame in their horses or their trainers, as they know there will be another day if only they make it alive through the race at hand. Jockeys are the true makers of this game — the jockeys and their mounts. In a jockey’s world, once the gate opens, everyone else is superfluous but their horse and the other horses and riders in the race. In a horse race decisions are made, yes, judgments upon which races can be won or lost.

Yet, with jockeys once the race is over, everything is superfluous. They are alive. They pinch themselves, yes, I made it. Jockeys leave the should-have-done-this, should-have-done-that for the next race. They adjust and learn from their mistakes to a highly efficient degree. Jockeys leave the riding commentary to the trainers and sportswriters. When jockeys comment negatively on the trainer’s ability, they often lose future mounts. When jockeys gripe about sportswriters, they get bad press. Jockeys are wise. Horses make one very wise, especially if one rides them in rough company for big money. Like horses, jockeys know when to keep their mouths shut.

You did not hear Kent Desormeaux criticize Big Brown’s trainer for failing to adequately prepare the horse to be in a partnering mood last year. But indeed, the trainer failed to prepare the horse to collaborate with Kent. Brown was rank and washy and unmanageable. See last year’s summary of the Belmont, Horsemanship and Horseracing.

This year Woolley failed to prepare Mine That Bird to rate well over the Belmont route of ground, and whom does he blame? Calvin Borel, the Derby-riding savant.

The angst Preakness runner-up Mine That Bird was weaving in his Belmont shedrow all day. Weaving is a stereotypy improperly managed racehorses take up with. Seems Woolley was busy elsewhere other than in the shedrow where he should have been enriching his horse’s life before the Belmont. As a result, the Kentucky Derby winner took to cantering in place on the way to the paddock. Generally, this is not a sign that the horse has been prepared to rate. Racy horses do not rate well nor easily. The trainer is responsible for the condition of his horse. The mental condition of Mine That Bird was not conducive to rating the mile and a half Belmont. The trainer failed both the horse and the jockey.

Let us take a moment and bow our heads to the jockeys. They take all the risks and talk about none of them. They take criticism close-lipped and quiet-like, the true horsefolk they are. All the risk is theirs, yes, but the blame for losing a race is not theirs, not in the last two Belmonts at any rate.

Like horses, jockeys are survivors. They have class. Jockeys emanate class. The organization that oversees thoroughbred horse racing is called The Jockey Club for a reason. Jockeys rule this game quietly. Each and every race they are riding to survive, and riding well.

From my rabbit hole in the infield, I say let us all take our hats off to the game’s true friend. Here’s to the jockeys! Spills and wrecks will break their bones, but words will never hurt them.

Mine That Oxygen, a veterinary take on the Derby victory

Mine That Oxygen: a Vet’s Take on the Derby
By SID GUSTAFSON
Chalk that Derby win up to efficient use of oxygen. No mysticism or surprises in the equine physiology and podiatry camps, just good old dependable O2 at work, along with some nicely-nurtured hooves. Mine That Bird’s road trip from New Mexico brought the horse down into the oxygen the other runners in the Derby came up to, allowing a significant and readily apparent advantage as the race shaped up around the turn into the stretch run. Yes, the 135th running was a freight-train-passing-a-bum scenario if there ever was one, the bums being the other gaspers in the field groping for the oxygen that Mine That Bird sucked up down the stretch run ahead of them.

And some stretch run that was (and how did you like the call? The announcer seemed completely depleted of air.)

The outcome is not really all that surprising to the exercise physiologists and hoof bio-mechanicists laughing in the wings, not to mention the cowboys. Bird’s Rocky Mountain High conditioning stimulated the production of red blood cells by causing a release of endogenous erythropoietin naturally, and natural is the way to go these days as polo ponies attest.

High-altitude acclimation training is one of the oldest endurance strategies, and the affect appeared stunning. By the time Bird crossed the Ohio River into Kentucky his blood was attracting Louisville oxygen like Churchill Downs had attracted dreamers, sucking the stuff right of the air as we watched. If some of you are still wondering why you were feeling a bit lightheaded toward the end of the race, now you know why. I was sorry to hear a couple of ladies fainted, but such is the price to watch an oxygen harvester like Mine That Bird take a race.

Not only did Bird’s blood have the iron to carry the oxygen, his tremendous nares had the shape and flare to inhale the oxygen, much like his hooves had the shape and flare to handle the mud.

Did you notice the Bird had all four legs wrapped? Some consider leg wraps oxygen stockings, and after that performance more will become believers in the strategy. Lower leg pressure wraps can improve a runner’s max VO2 by increasing blood return from the legs to the heart. Additionally, Bird’s body shape and flying style made the perfect oxygen-assimilating piston, as did Calvin’s aerodynamic ride. With horses, each gallop is a breath you know, breathing being interconnected with running, a breath per stride. Did the mathematicians get Bird’s stride count? When they get it all added up, Bird outstrode the also-rans, outstriding equated to outbreathing the competition, enhancing his aerobic capacity further.

Note the oxygen miner’s nose and throat. The winner has the finest nostril flare of them all, pouring the essential horse racing juice into his lungs, to his big heart, to his gliding muscles, gliding muscles harboring a sweet reserve of oxygen to accelerate down the stretch run.

Like his black hooves handled Kentucky mud, his nostrils and blood kept him metabolically astride. The Miner held sway, I’d say, and would have most likely held sway against Rachel and Revenge had they chose also to follow him across the finish line.

With glide like his, Mine That Bird hydroplaned over the Kentucky mud. Yes, it appeared the horse did not break the surface tension like the other plodders along. Those water bugs that run across ponds, what are they called? Boatmen, yes, Mine That Bird’s hooves became his four boatmen, so oxygenated he was. Mudder hooves, yes. Mudder physique, yes. Mudder stride, yes.

What else made this the best Derby ever? Mudder lightness, as in the tapering trailer ride from the mountains. Tapering? you ask. The strategy of reducing intestinal volume to enhance mobility and flight is long practiced, and in this Derby metabolically perfected by New Mexican cowboys, whom it appeared also lost a few pounds on the trip to Louisville, and perhaps will lose a few more as the Triple Crown wears on. Tapering not only reduces a horse’s weight, but it also prepares them physiologically to run a route of ground. It appropriately alkalinizes them, naturally. With a Birdstone horse like That, why Woolley thought he ever needed to ride a motorcycle we will never know.

Gelding, the only gelding in the field wins. Gelding allowed man to domesticate horse like gelding allowed the Bird to win the Derby in gentlemanly fashion. Mine That Bird’s mare mining days ended some time back. On May 2 the Bird mined both oxygen and mud most efficiently. He did not have to bother himself with the hundred plus fillies in heat around the Churchill Downs backside that morning. No, Mine That Bird focused on running, and that lightened his load considerably, as well.

Before we end here, let us all express our gratitude to Mary Scollay, the equine medical director for the Kentucky Horse Racing Commission, and her professional team of regulatory veterinarians for effectively representing the health and safety of all the 20 horses entered in the Derby this year.
