Today, I found out my garden dog shocker wasn't working after coming home
and finding my new rescue dog full of manure, compost and mud. She got into
the fresh flower bed.

The wire shocker there apparently got wet and fried. I took it apart, let
it dry for hours, put it back together, and touched the terminals with no
shock. Outside of case says: 110v. AC in, .27amp, 60 hertz, 10 watts.
These Fi-Shocks are about $25 new. Where would I get a transformer like
this? When I looked at the transformer, it's marked 311-158 R2 10 2000.

The first part is probably the part number, the 10 2000 the date it
was made.

How do I read this to buy another cheapie, and where?

These guys sell what appears to be it for $30!!

You're probably better off buying a new on for the $25 or whatever.

120:800VAC transformers are not common and safety is an issue.

p.s.

Just to expand on this safety thing a bit.. I have not looked inside
the continuous kind of electric fence energizer, but I'd expect to
find a special transformer designed to have a lot of leakage
inductance as well as proper mains isolation and step-up ratio (and
not much else). The consequence of that is that the short-circuit
current would be limited to a relatively safe value (relatively safe
for animals and relatively safe for the transformer's health). This is
not a regular transformer, I suspect.
