I am not so good with giving hucow ideas, but if you can, you can set rules for yourself.
Such as minimum time for being naked and walking on fours.
Eating while being pumped,
Stuffing food in the mouth and chewing it for a long time.
Having a bell tied on your neck.
Tie your legs so you can not unfold them. Making you walk only on your knees.
#safety: it's better if you walk on your knees on a smooth surface, so as not to damage the knees.#
If you have a good camera phone or something , you can try to record everything you do, and later on, see how good of a hucow you are.
Moo once in a while so keep the feeling.
Keep your ass high while you piss, as you can't really hold a tail high for a specific time and lower it later on.
If you want to pleasure yourself, try using a suction stick or wall-mounted dildo, without using your hands.
If you are up for body modification, then try using a large nose ring.
I hope this few things can help you.
Also other doms see if there is something wrong in the things i posted. I will change them.
