The History of Las 
Rocosa Aussies 
  
Chapter II:  Developing a Bloodline of Distinction 
   
We started our bloodlines 
with Hartnagle’s Badger (Ely’s Blue and Christensen’s Buster) and Hartnagle’s 
Goody (Ely’s Feo and Ely’s Blue).     
| 
  "Badger"
 | 
Ely’s Feo was brought to the United 
States by a herder from the Basque country in Andorra.  The herder was 
employed by the Warren Livestock Company at the time. | 
 
 "Goody"
 |    
Juanita Ely, a rancher, 
was one of the oldest documented breeders in the country. She had acquired her 
first Aussie in the 20s with two bands of sheep she bought in Idaho.  As a 
livestock person, she knew the value of recording the lineage of the dogs, 
to preserve and establish them.  Juanita recognized the need to need to 
register the ancestry of ‘Blue Australian Shepherds,’ and was largely 
responsible for contacting Ed Emanuel at the National Stock Dog Registry (a 
division of the IESR) to use their services to register the breed.    
Juanita Ely used her dogs to 
herd their several bands of sheep and cattle on the range in the harsh working 
conditions (thick cactus, heavy crusted snow, heavy underbrush), rain or shine 
in the real world. Ely’s Blue, the dam of both Goody and Badger had been proven 
on the ranch, day in and day out.   
We traded Goody to a very 
close friend of ours who owned Jinx, a litter sister to Goody, who ran a very 
large sheep operation in southern Colorado.  Jinx had gotten crippled by a 
broken shoulder.  Even though Jinx worked on only three legs; when it was 
time to gather sheep on our place in the Boulder Valley, my father would send 
Jinx.  She would disappear in the horizon until finally she had gathered 
every ewe and brought them down the lane along the creek.   
Goody’s next four years were 
filled with every description of hardship and irresponsible herders.  One 
day, one of the herders suffered a heart attack while out on the range.  
Little Goody watched over him and guarded him for three days (without food or 
water), and protected him from predators until our friend, Joe Fernandez, found 
them.   
Goody was then mated to her 
sire, Ely’s Feo while at the sheep ranch. It was there that she whelped 
Hartnagle’s Goody II (Ironhide), a dog who later became the foundation matron 
for our Badger line. Goody II was named “Ironhide” because of her tireless 
endurance. She was fearless.  She worked stubborn rams, or handled bulls 
just as easily.  Goody II was inbred Feo.     
The Badger line had courage, 
longevity, and staying power. We admired these characteristics and continued to 
breed for them.  Once when working a single Brahman bull, Badger got 
tromped pretty hard.  Dad thought the bull had killed him.  He sadly 
picked up Badger’s limp body and laid him aside, so he could bury him beneath 
the lilac bushes at the house.  Apparently, the bull had just knocked him 
out cold.  After a few minutes, he came to and shook his head.  The 
next thing we knew Badger went back to work and put that bull in its place.   
	
		| 
		The years progressed and 
Badger (1954 - 1969) entered his twilight years.  Mom and Dad traveled 
many, many miles all across the country looking for a suitable replacement for 
Badger.  It was no easy task.  Finally Hartnagle's Hud came into our 
lives.  He filled the bill beyond our wildest expectations.  He was 
everything we had hoped for and more, and he proved it time after time.  
Hud was intelligent, athletic and fun to have around.  He never held a 
grudge.  Hud was a clown, but when it came down to business, you could 
trust him with your life. If a mad mother cow or a grizzly bear had you pinned 
to the ground, Hud would protect you even if it cost him his life. He was 
dependable.  As tough as he was with rough stock, he was equally as gentle 
with babies. | 
		 
		
		 "Hud"
 |    
| 
 "Fritzie"
 | 
We were so pleased with Hud 
we decided we had to have a female of the same cross. 
Hartnagle's Fritzie Taylor 
and Hud were by Taylor’s Whiskey and out of Taylor’s Buena.  Whiskey and 
Buena also were proven by hard, continuous ranch work in real working situations 
where they learned how to handle themselves in all types of terrain and under 
varied conditions. |      
| 
 "Shiloh"
 | 
Shiloh’s dam was a full 
sister to both Hud and Fritzie Taylor, who were all of the same family lineage. 
These dogs were sound, athletic, had stock savvy, were able to face a stubborn 
ram with authority, and who were undaunted by cattle.   
Not only did Shiloh have 
heart, trainability, stock savvy, power and endurance, he had a style all his 
own.  He was the Champion of Champions.  Shiloh worked like a cat on 
the hunt.  He could handle anything and without even asking, he would 
gather the stock and bring them to us.  If something tried to break away 
from the bunch and tried to escape, it did so only once before Shiloh put it 
back in its place.  He had the uncanny ability to read and rate whatever 
was being handled.  Shiloh was prepotent for reproducing his natural style  
(the distinctive performance which is a combination of intelligence, working 
attitude; concentration and force), consequently today, you’ll see many Aussies 
exhibiting a stylish blend of eye and a natural fetching style, with balance. |    
| 
Both Leslie and Shiloh were 
sound, athletic, dependable, could head and heel with equal ease.  They 
demonstrated above average stock savvy, trainability and willingness to please.  
And most importantly they were tried and tested against the yardstick of 
performance.   
We felt the cross between 
Shiloh and Leslie would be a cornerstone for the future of our bloodline.  
The cross was made and produced Las Rocosa Lester.  Lester was bred to only 
a few of our very select bitches and for our own use.  His record is 
unsurpassed.  He went on to sire some very prominent working dogs who (by 
virtue of line breeding) were able to transmit the qualities of their ancestry.  
Lester was one of our most prepotent sires (capacity to transmit those qualities 
back to the offspring) whose offspring have stood the test of time, and have 
gone on to make their own mark on the breed, many of which are recorded in the 
ASCA Hall of Fame. |   
 "Lester"
 |    
| 
 "Kyle"
 | 
Working Trial Champion Las 
Rocosa Bonny Kyle RDX (a linebred Shiloh) sired by Lester born in the fall of 
1981 worked anything (ducks to cattle) with enjoyment, though his first love was 
cattle.  His natural working style was ideal for handling cattle and 
typical of his illustrious ancestry.  He could head or heel with equal 
ease.   
On the range, Kyle 
demonstrated his ability to handle the rankest range bulls or the maddest mother 
cows without hesitation.  With his intricate sense of balance to read and 
rate stock, Kyle was pure power with a stylish blend of eye.  Time after 
time, Kyle has proved he had the heart to go the distance, even when the going 
got tough. |    
| 
As we 
developed the Las Rocosa bloodline, we knew we also wanted to maintain the 
traits we highly admired in the Badger line.  We were able to do that with 
Champion Stonehenge Justin Case of Las Rocosa CD.  Justin Case was by 
Champion Las Rocosa Shiloh and out of Champion Shanahan’s Phantom CDX.  
‘Fanny,’ was a descendant of Hartnagle’s Jinx who was later registered as Dye’s 
(Deines’) Jinx in the Stock Dog Registry.   
Justin measured up in every 
way. He embodied the type of temperament (trainability and intelligence), 
working style, stock savvy, soundness and athletic ability we demanded in our 
dogs. He proved his value as a sire, by passing on those same characteristics. | 
 
 "Justin"
 |    
| 
 "L'Oreal"
 | 
We have 
always recognized it is vital to evaluate every generation to determine the 
qualities and characteristics that are being perpetuated.  It  
eventually came time to appraise the cross that produced Las Rocosa L’Oreal (Las 
Rocosa Lester and out of Las Rocosa Cornflower who was also by Lester). This 
litter was linebred on Shiloh, and inbred Lester.  As the litter developed 
and started working, we evaluated that indeed the offspring personified the 
beneficial attributes of the ancestry. The owner of Las Rocosa Poco Lena ATDsd 
OTDc (L‘Oreal‘s littermate) wrote: “Lena grew up to be a very stylish worker, 
with the eye and class that Lester is famous for producing.”  He 
continued to write: “She is very prepotent for her type and style and her 
puppies are sociable and very trainable.” |    
When it came to handling stock, L’Oreal used eye to balance and control 
livestock.  She worked on her feet with authority, and could head or heel 
as the situation demanded.  L’Oreal was structurally sound and able to 
dodge horns and hooves with superb athletic ability.    
L’Oreal exhibited 
intelligence, but we found she was extremely independent.  She typified 
everything we had been breeding for, except for that one trait. We have always 
bred Aussies that were able to think and act independently, but that were 
willing to listen and take direction…and that we were not going to compromise.  
After carefully deliberating, we decided to breed L’Oreal to Champion Just Jake 
of Las Rocosa.  Jake was by Champion Stonehenge Justin Case of Las Rocosa 
CD.   
The criteria on which we chose Jake was his outstanding temperament and proven 
working ability.  His disposition was delightful to live with.  Jake was willing 
to listen and wanted to please.  He had a unique ability to work his way into a 
pen, packed tight with sheep, up against the fence and move them off with pure 
power. We never worried about Jake biting erratically and injuring the sheep.
	 
  
			
				
					| When Jake was only nine months old we used him to move 1500 head of sheep 
	out of the Mountains of Utah into Colorado. He herded on pure instinct and 
	was able to think independently without being told every move to make, but 
	exhibited willingness to listen for redirection. |

 "Jake" & "Leo"
 | 
Years later, in 1987, I used Jake on the government project for working Wild 
	Bison for the Department of Interior in Yellowstone National Park.  This was 
	a dangerous job.  We chose Jake because he was dependable and level-headed.  
	He was sound mentally and structurally.  |    
	
		
			| 
Jake demonstrated the qualities we value so highly in the Australian 
	Shepherd. Jake was unafraid. He had the power to handle large numbers of 
	sheep on the range, he was able to and would stand up to an obstinate ram 
	and was fearless of a charging bull, yet gentle enough to send in a pen of 
	lambs in order for him to nose them out of a corner.   
The cross between L’Oreal 
and Just Jake produced Las Rocosa Katy Did It DNA CP.  Katy became an ASCA 
Hall of Fame Dam for producing WTCH Las Rocosa Western Legends RTDs DNA-VP,
CH 
Las Rocosa Take This Chance OTDs STDcd, WTCH LasRocosa Whispers Success RTDs 
DNA-VP and WTCH Las Rocosa Red Hot Hanna RTDcs. |    "Jick, Little Wolf &

  A successful breeding program has to be based 
on more than blue ribbons, it has to be built upon a strong foundation that is 
tested from one generation to the next proven by the yardstick of 
performance.   
Note - The point of inbreeding (the 
practice of breeding two dogs that have close-up ancestors in common (daughter 
to father, mother to son, and brother to sister matings) is to get the progeny 
as predictable and consistent (homozygous) as possible.  Line breeding is a 
type of inbreeding, but not as intense (cousin to cousin, niece to uncle, nephew 
to aunt matings).   
Both inbreeding and line 
breeding tend to cut down heterozygosity and variability in the offspring, while 
fixing (setting) type by increasing uniformity (homozygosity).  The type 
being fixed is selected by the breeder and governed by the traits exhibited in 
the ancestors.  If the breeder ’selects’ Aussies with genes for a specific 
working style or character, then by inbreeding, it is possible to get 
these genes in homozygous condition to reinforce them in the family line 
involved.  This breeding system (staying in the family) should only be 
practiced when intensifying the good qualities through line breeding and 
weeding out the poor and inferior genes.   
Let me make it very 
clear.  Inbreeding or line breeding should ONLY be practiced if the 
ancestors and individuals involved are healthy and free from genetic disorders, 
intelligent, structurally sound, and possess proven working ability of the 
desired type.  If so, then inbreeding can be constructive.  Inbreeding 
does not cause the offspring to be more liable to manifest a disorder, less 
hardy, or cause a decrease in size, unless those characteristics are already 
present in the genetic makeup.    
It is correct that 
inbreeding and line breeding intensify a strong constitution, good bone, vigor, 
and working ability OR a weak constitution, lack of vigor, delicate bone, or 
lack of working ability, if these traits have been well developed in the 
bloodline.     
Out-crossing is a better 
breeding system for inexperienced breeders because unrelated dogs would not be 
as likely to double up on the same harmful genes.  However, two different 
bloodlines can carry the same recessive detrimental genes.  In developing a 
bloodline it is also necessary to out-cross to maintain strong, healthy immune 
systems, which are dependent on genetic diversity.
