A beginner, I bought a Canon Digital Rebel XT and looking for two lens.

One that has a good zoom, EF75/200 ?
One good macro lens?

I need to take pictures of dogs working, they may be 50 to 100 yard
away, and really close shots.

 To get close shots of dogs that are 100 yards away, you will probably want
something with a bit more range than a 200.  Also, if the shots are pretty
close, then 75mm will probably be a bit too long.   A 28-300mm L lens would
seem the most appropriate, but of course, it's a pretty expensive lens.
Sigma makes a 28-300 that's about 1/5th or 1/6th the price of the Canon "L"
lens, but with a commensurate drop in quality.

 The armchair quarterbacks often fail to realize that there are plenty of
real-world situations where you have about three seconds to go from a
distant subject to a very close one, and if you miss it, you miss it.  And
when that's the case, a shot of somewhat lower quality is still better than
no shot at all - and the "lower quality" of the 28-300, being a true "L"
class lens, is still pretty darn good.  I'd personally trust it much more
than a $300 EF-class lens.

 Sure, if he had all the time in the world and money to burn, he could go
with a 100-400 "L" and a 24-70 "L" - or even primes - but from his
description, it sounds like he doesn't exactly have that luxury.

Two bodies!!!!  Yeah that would solve the problem.   ;-)

And generate others.

The multi-body solution was a handy one back in the F-1N, A1, AE-1,
AE-1P era. My arrangement was the first two hanging ready and the
other two in a big bag, also hanging.

Couple weeks ago I went to a luncheon-picnic and as another fellow
present said, was "loaded for bear": 20D / Canon 24-70 L and RebXT /
EF-S 10-22; Nikon CP 8700 in a fanny-pack worn in front.

I'm not as strong as I was twenty years ago, and apparently not as
staminous, either. After an hour or so lugging that load around,
minding their trajectories in all dimensions, I was ready for a break.
It was much more pleasant and productive to leave the bag and one
camera under the eye of a companion, and hit the high spots with the
other camera, coming back to switch. All that to avoid changing lenses
in a dusty environment.

I'd reckon a few weeks of every-other-day practice at that, I'll be
ready for an upcoming three-and-a-half-day project. Adjusting to the
weight will come naturally. Perfecting the two-heavy-camera ballet has
the potential to be costly. It is no trivial exercise to move into
position, choose and swing into readiness a camera while keeping
another safe and unobtrusive.

In such circumstances I'd seriously consider a super-zoom trade-off of
convenience for slightly diminished quality. If I weren't beginning to
learn to appreciate some of the subtle differences between "regular"
and "L" products. And if the zoomer would start a good deal wider than
the currently available examples. 28-300? Yes, but ...

Decisions, decisions.

Reminds me: weight and size not withstanding, I wish I'd waited that
couple months and saved up for a second 20D: the RebXT is a nice
camera with excellent output, but the 20D is much easier to control.
Rather, it makes me a much better controller with less perceived
effort.

I'll start on that weight training and conditioning program after this
long weekend. Yes I will.

Bev-

At 100 yards, a dog may be hard to recognize as a dog if you use the 200mm
zoom lens.  Steve Wolfe's 100-400 L lens suggestion is the closest you
might be able to use, and I expect you would be disappointed at the
greater distance.  It would be a good idea to try-out a lens before
spending that kind of money, to be sure you can use it at all.

If you take a picture with a lens you have, you can estimate the focal
length you need.  If the subject needs to be ten times as big in the
resulting photo, you need a lens with ten times the focal length.

Longer lenses often have smaller maximum apertures, resulting in slower
shutter speed and a greater chance of camera-shake.  Unless you use a
tripod, you should also consider a lens with the Image Stabilization (IS)
feature.

A newbie thought here (i.e. take with a grain of salt)

What about the EF 28-135/3.5-5.6 IS USM (i.e. 45-216) and then a macro
lens in addition?  Or would 216 not be sufficient for the 50-100 yard
range?.

Here's a dog, small, one each, taken from about thirteen yards
distance, with a 300mm lens:

http://www.fototime.com/34B0BA5E8869D4B/orig.jpg   et in the corner

300mm Full frame
Canon EF 70-300 f/4.5-5.6 DO IS
1/400 @ f/7.1 Canon 20D
Hand-held IS Auto focus
Reduced to size in 10% decrements
Unsharp Mask 100%, 0.4, 0, Fade USM
Save For Web at Photo Shop 30 quality

I estimated the distance to be twenty yards, but when I measured it
with a metal tape, it was quite a bit less. I wonder if the OP is
accurate in the 50 to 100-yard distance specified.

Have you thought about the Canon 70-300 DO lens? It's reasonably fast and
small enough that you're not going to be worrying much about it.

I've shot with a 70-200 f/2.8 L lens. Beautiful photos but too much weight
for the kind of application your are looking for.

For macro get the Canon EF 100mm f/2.8 its an excellent macro/portrait lens.
However for dogs and close up shots a 50mm f/1.4 would probably be better.
Here is an example of a close up of a dog with the 50mm f/1.4 lens

For the reach you might do ok with a 70-200L f/4 an excellent lens, and if
200mm isn't long enough go for the Canon 100-400L also an excellent lens.
