Frequently Asked Questions (FAQS);faqs.249
To train adult dogs, or continue the puppy training as an adult, is
relatively simple. Some dogs are natural pullers, others are not.
Some dogs take right to the harness the first time, and other dogs,
even ones from reputable breeders, may take extensive training. You
just never know.
It is vital to get the dog to lean out and keep the line between it
and you taut. Some dogs have a real problem with this, others do not.
For problem dogs, the cause usually is due to the dog not liking you
to be behind it. If you do have trouble, there are a variety of
methods you can use. As long as you make training a fun game, and you
make the dog understand what you want it to do, training will progress
quickly, even for stubborn dogs, like Siberians. Fortunately, they
LIKE to pull, so their stubbornness is not a problem here. Sometimes
getting them to STOP pulling is!
Some mushers feel that it is best to train dogs to pull lots of
weight, then speed comes naturally in a race without the weight.
Others feel that speed and endurance training is best. Still others
feel that a combination works best, similar to the combination
training for the musher. Training for speed and endurance by mushing
shorter distances (under 10 miles, sometimes even 3 or 4 miles) at top
speed and up hills is beneficial. Loping along at 3 or 4 miles an
hour for 15 or 20 miles is also beneficial. Both of these build
strength and endurance. Pulling heavy weight for short distances is
also quite good, particularly for wheel dogs (the ones hitched closest
to the sled). For this, try a plastic tub to which you can add
plastic weights (the ones from barbell sets will have the weights
printed on them).
Whichever method you use, remember to take it easy with your dogs and
not push them to hard, and never, NEVER, lose your temper with your
dogs. Remember that this is supposed to be fun for both you and the
dogs. George Attla, a famous musher once said, "If the dogs make a
mistake while out on the trail remember that it is not the dogs that
have made the mistake. It is you." For additional training
information (with much more detail than is practical to provide here),
see the references.
10. Training lead dogs
To successfully mush, one must have a good lead dog (or dogs). This
dog will take your commands for regulating speed and direction for the
entire team. Naturally, if you are driving only one dog, that will be
your lead dog.
Training lead dogs is too complex to really do it justice here. The
basics are you want the dog to learn to turn right, left, speed up,
and slow down on voice command. You also want the dog to bypass
interesting detours and distractions. In addition to the basic
commands already introduced (see section 3), the dog must also be
taught the commands below:
kissing sound : Speed up (or other appropriate sound)
on-by : Go by a fork in the trail, other dogs, or
other distractions without detour
All commands are spoken in a firm, calm, not too loud voice.
During training, you must be certain to use varied turns and trails to
be sure that the dog is really executing the commands rather than
following a well worn path. You must also anticipate the turn and
issue the command at the correct time from the *dog's* perspective.
Finally, some people get confused when issuing the right/left
commands, particularly in the excitement of a race. Some mushers tape
the commands on the front of their sleds, on the right and left sides.
You may want to do this while beginning on the sled.
To train a dog to execute these commands with regularity is not too
difficult. To train a dog to do this during the excitement of a race
with lots of distractions is more difficult. One possible way to
approach training is to start out on foot when the dog is a puppy.
Keep the lessons varied, quick, and fun. Be certain to do the lessons
in a variety of environments, with and without distractions. When the
dog is old enough to pull weight (about one year to 18 months, get
advice from your veterinarian), you may wish to graduate to cross
country skiis. The dog will learn to execute commands in snowy
conditions, and at higher speeds. Once you have your lead dog well
trained and pulling your sled, you will find that other untrained,
young, dogs can be very easily added to your team as your lead dog
will "correct" the new dog's mistakes, usually faster and better than
you can.
This is one way in which lead dogs can be trained. Consult the
references and experienced mushers (if you can find any) for
additional information.
11. Training for weight pulling
Here emphasis is on strength and pulling straight no matter
how difficult. Most of the mushing books in the references discuss
weight pulling training.
12. Training for skijoring
Skijoring is you on cross country skis and the dogs pulling you. YOU
MUST BE A VERY GOOD CROSS COUNTRY SKIER. This is a must. Before
attaching dogs, cross country ski all over the place, on a wide
variety of terrain. Learn to fall in a controlled way. You will
eventually need to do this when skijoring. You will need to learn to
turn quickly and ski in control at high speeds. Skiing downhill in
cross country skis is a good way to simulate skijoring speeds.
The dog(s) must be well trained as well. Train all of them as lead
dogs. They need to know and obey all of the commands very well
(especially whoa!). The references all include information about this
fast growing sport.
13. Health, diet, and care -- Sled Dog Specifics (briefly)
Sled dogs are athletes. They are also remarkably healthy. It is
important to realize that because sled dogs are athletes, they require
special attention in at least two specific areas.
Probably one of the most important aspects for caring for sled dogs is
the foot. You should inspect your dog's feet regularly. The skin of
the pad should feel tough, but pliable, be resistant to abrasions and
lacerations, and be free from cracks, dryness, or scarring. Also
inspect the nails of the foot carefully. Nails can help the dog grip
ice, but if too long, they can cause serious foot injury. According
to Miki Collins in _Dog Driver_, if the nails are long enough to force
the toes upward when the dog is standing on a hard, level surface,
clip them. Nails that are too long can get caught and ripped out on
the trail, or they can cause toes to break. Both of these injuries
can be quite serious, and they are certainly painful.
The subject of diet should also be touched on here. Most mushers feed
a high stress, high energy diet during mushing season, and switch to a
"maintenance" diet during the "off" season. For example, one
experienced musher mixes Science Diet Performance dry with canned
during mushing season. This is a high fat, high protein food. Some
mushers even mix food in with lots of water hours before a race to
encourage drinking. Dogs must be very well hydrated. During the off
season, the musher in this example feeds Science Diet Maintenance
canned mixed with either Science Diet Maintenance dry or Eukanuba dry.
During the mushing season, the dogs are using all components of the
food that is fed. During the off season, there is no need for such
high energy food, and in fact, high protein foods can cause kidney
trouble later in life when not fed in moderation.
14. Final remarks
Hopefully, this brief summary has been helpful to you. Even if you do
not want to get involved in mushing yourself, try and find mushing
events in your area. It is wonderful to see the handsome dogs
enjoying doing what they were bred for.

K. Gaming Dogs.
1. Frisbee
There are serious competition trials for dogs playing frisbee.
2. Flyball
Thanks to Ian J. Hogg.
Flyball is a team sport for dogs. It is a relay race with 4 dogs on a
team. The dogs jump over 4 hurdles spaced 10 ft apart and then
step/jump/throw themselves into a spring loaded box that shoots out a
tennis ball. The dog catches the tennis ball and then runs back over
the 4 hurdles. When the dog crosses the starting line the next dog
goes. The first team to have all 4 dogs run without errors wins the
heat. There are three heats per race. The winner of each heat
receives 2 points towards their standing in the tournament. The dogs
earn points towards flyball titles based on the teams time:
less than 32 secs: Each dog receives 1 point
less than 28 secs: Each dog receives 5 points
less than 24 secs: Each dog receives 25 points.
The titles the dogs can earn are
FD Flyball Dog 20 (25?) points
FDX Flyball Dog Excellant 100 points
FDCH Flyball Dog Champion 500 points
The really good times run about 19 seconds. The hurdles' height are
dependent on the height of the dogs in the team -- 5" below the
shoulder height of the shortest dog. 10" is the minimum height and
16" is the maximum height.
Anyone with a dog that loves balls can give it a try. Check to see if
obedience schools in your area have teams.

An elegant method for designing a time-discrete solution for
realization of a spectral window which is ideal from an energy
concentration viewpoint. This window is one that concentrates the
maximum amount of energy in a specified bandwidth and hence provides
optimal spectral resolution. Unlike the Kaiser window, this window is
a discrete-time realization having the same objectives as the
continuous-time prolate spheroidal function; at the expense of not
having a closed form solution. [Joe Campbell, jpcampb@afterlife.ncsc.mil]

Q1.2: Where can I get free software for general DSP?
The packages listed below are mostly for general purpose DSP, that is,
DSP that is not specific to a particular programmable DSP chip. See
the later sections in the FAQ for software relevant to a particular
programmable DSP chip.
According to Brian Evans: "There was an entire session on this subject
[free DSP software] at ICASSP '92, chaired by Dr. Sally Wood and
Dr. James McClellan. It appears in Volume 4 of the Proceedings, pages
73-112. There will be another such session at ICASSP '93." [Brian Evans,
evans@eedsp.gatech.edu] Much of the information below is from Brian's mail.
