READ OUT LOUD. Choose which marked text you prefer to practice with - macrons in verse form, or macrons in prose order, or accent marks in prose order, or focusing on the meter. You will find materials for all of these options below. :-)
VERSE MACRONS. Here is the verse text with macrons:
Ōre ferēns carnem, liquidum dum trānsmeat amnem,

Esse putāns carnem dum dentibus appetit, illa

Quī sua parva putat, aliēnaque tollere tentat,

PROSE MACRONS. Here is the same text with macrons written out in prose word order:
Canis, carnem ore ferēns, dum amnem liquidum trānsmeat, carnis umbram in amne prōspexit . Dum dentibus appetit, putāns carnem esse , illa quam tulerat cecidit, et umbra nulla fuit. Quī, mōre canis, sua parva putat, et aliēna tollere tentat, perdet quod cupit et quod habet.
STRESS (ACCENT) MARKS. Here is the prose text with accents, plus some color-coding for the words of three or more syllables (blue: penultimate stress; red: antepenultimate stress):
Canis, carnem ore ferens, dum amnem líquidum tránsmeat, carnis umbram in amne prospéxit . Dum déntibus áppetit, putans carnem esse, illa quam túlerat cécidit, et umbra nulla fuit. Qui, more canis, sua parva putat, et aliéna tóllere tentat, perdet quod cupit et quod habet.
ELEGIAC COUPLET METER. Below I have used an interpunct dot · to indicate the metrical elements in each line, and a double line || to indicate the hemistichs of the pentameter line.
Ōre fe·rēns car·nem, liqui·dum dum· trānsmeat· amnem,

Esse pu·tāns car·nem dum· dentibus· appetit,· illa

Quī sua· parva pu·tat, ali·ēnaque· tollere· tentat,

IMAGE. Here's an illustration for the fable (image source) by Walter Crane:

What follows is an unmarked version of the prose rendering to faciliate word searches:
Canis, carnem ore ferens, dum amnem liquidum transmeat, carnis umbram in amne prospexit . Dum dentibus appetit, putans carnem esse, illa quam tulerat cecidit, et umbra nulla fuit. Qui, more canis, sua parva putat, et aliena tollere tentat, perdet quod cupit et quod habet.
