I have a dog waterer that has a female garden hose connection. I would like to take a tee off my 3/8 compression fitting above my cut off valve under the sink to connect to this. Any suggestions on the best route to go? I would prefer to stick with a short braided hose like you would use for a toilet to make the run… But I have no idea how to take a compression fitting to a garden hose.

The easiest way to achieve what you are looking for with what you already have is to:
- Shut off the water at the angle stop shown in your first photo (confirm that the valve is closed by opening the cold on you sink)
- Cut the copper tubing in half (the tubing between the angle stop and the second valve)
- Install the valve tee shown in your second photo (this will reconnect the cut tube)
- Test (by opening the angle valve)
- Slowly tighten the compression fittings if they are leaking
Here's a video on how to install compression fittings: Youtube video.
You're going to need to get a 3/8" x 3/8" x 1/4" brass tee, like this one from Home Depot.
Then you'll simply screw the tee onto the male end of the shutoff valve (where the cold water supply line should currently be attached). Attach the supply line (that you removed from the shutoff valve) to the male end of the tee. Finish the installation by attaching the tubing to the 1/4" outlet using a compression fitting (Which should be included with either the filter or the tee).

Not knowing what your valves under your sink look like , I would suggest possibly a new valve with 2 ports or the addition of a T on a 3/8 fitting then you could find a pre made hose like you want for a Refrigerator, this can feed your waterer.
I would want an independent shut off incase of problems, my plumbing speciality store could set up all the parts needed and suggest things like an extra valve just in case by using a photo of your existing under sink set up. They may cost a few dollars more but 1 trip ends up saving time and frustration in the long run compared to the big box stores , the big box may have what you need but getting the correct help sometimes it tough.
