100% appropriate, IMHO (though see below*).

I have not heard of this being done successfully, but I *AM*
"speaking" off the cuff.

This is what most people do.  I'm pretty sure that the standard
amphotropic vectors will work fine in dog cells.  Muscle cells might
present problems, however, as retroviruses can only infect replicating
cells.  Myoblasts might be ok, if that will do.

We have looked for a good cookbook on these kinds of techniques and
have not found one.  This may be because the techniques change to
rapidly.  All I can suggest is a full blown Medline search.

Once you are searching, look for the new approaches which use
asialoglycoproteins and adenovirus to increase transfection
efficiency.  This might work well for muscle cells.

* You ask for email responses due to a lack of good access to bionet.
I sympathize, but strongly encourage you to try to improve this
situation.  In the first place, this topic is one for which an
_exchange_ on the newsgroup might be better than a simple collection
of replies.  Further, once you have collected email responses, it is a
nice thing to do to post a summary to the group for the help of
others.  Finally, you would be suprised at the number of good ideas
that come from following the group regularly.
