The first glance I took and my brain saw "I want to eat the dog"

"Bwyd" (food) comes ultimately from Proto-Indo-European "*gʷeyh₃tom", from "*gʷeyh₃-" (to live), of which also descend Welsh "byw" (to live; alive) and "bywyd" (life), Irish "bia" (food; substance) and "beatha" (life), English "quick", Latin "vīta" (life [whence Romance "vida/vie/viață"]) and "vivus" (alive [Romance "vivo/vif/viu/bibu"]), Ancient Greek "βῐ́ος/βίοτος" (bíos/bíotos, “life” [as in biology, biosphere and bionic]) and "ζῷον" (zôion, "animal" [as in zoology) , Russian "живот" (život, "belly; (archaic) life"), Lithuanian "gyvatà" (“life”), Sanskrit "जीवित" (jīvitá, "living; life"), Avestan "gayo" ((accusative "ǰyātum") "life"), etc.

"Time for chores. Do you want to feed the dog or scrub the toilet?"

As "the dog" is "y ci" how does it become "..bwydo'r ci" and not "bwydo y ci"
