"The boy is eating pizza and the dog is eating rice."
Translation:Der Junge isst Pizza und der Hund frisst Reis.
would it be weird or "offensive" to say an animal "isst" instead of "frisst"?
No. Especially if it's considered part of the family (e.g. a cat or a dog), you can find isst in relation to an animal.
For example, try googling was isst ein(e) ... versus was frisst ein(e) ... for various animals (ein Hund, eine Katze, ein Kaninchen, ein Reh, ein Pferd, ...) and see how many hits each version gets.
"Der Hund" is the subject of that clause "Der Hund frisst Reis." You conjugate the noun based on whether it's the subject/object/etc. in the sentence, not just by what the verb is.
So just like we would say "I eat rice," with the subject form "I," we're going to use the nominative "der Hund" for "Der Hund frisst Reis." We use accusative "den" for "Ich esse den Apfel" because "den Apfel" is the direct object. (Just like "I eat he" is not grammatical; you would need the object form "I eat him.")
the sentences is not Accusative ?
No. Sentences are not accusative or dative or any particular case. Parts of sentences are in a case to show their role within the sentence -- e.g. nominative for subject, accusative for direct object, dative for indirect object, various cases after prepositions.
I hot this right just not using capitals. You marked it wrong?
Duolingo (unfortunately) ignores capitalisation.
If you were marked wrong, it's unlikely to be due solely to mis-capitalisation.

Is the grammar really correct here?
In college, they taught us that a second verb goes at the END of the sentence.
If you have a clause containing more than one verb, then one of them is finite (has endings that depend on the subject), and the others (participles or infinitives) go at the end of the clause.
A simple sentence consists of just one main clause, in which case, the verb at the end of the clause will also be at the end of the sentence.
Duo's sentence here, though, consists of two main clauses:
- der Junge isst Pizza
- der Hund frisst Reis
each with just one verb, joined together with the conjunction und.
There's just one verb per clause and no reason to move anything to the end of anything else.
Now, if you had something like
- der Junge wird morgen Pizza essen
- der Hund hat gestern Reis gefressen
then yes -- the second verb in each clause goes to the end of that clause and you end up with Der Junge wird morgen Pizza essen und der Hund hat gestern Reis gefressen.
Why do i get it wrong when reis is not in upper case
Duolingo unfortunately ignores capitalisation.
So it would surprise me to hear that Duolingo would reject a sentence merely because you wrote reis (incorrectly) in lower case.
