Grammar correction worksheet featuring a story about a mini schnauzer named Barney.

Let’s go through the paragraph line by line and find all 10 mistakes — including punctuation, capitalization, and grammar.

Original paragraph:

> I love playing with my dog barney He is a mini schnauzer, and is the best dog in the world. His favorite thing to do is to go on walks when he smells everything? once, he saw a skunk and Chased it but instead of running away the skunk sprayed him! That was funny? After his walks, Barney loves to go home where he gets a reward for behaving well. He earns a treat every time because he is such a Good dog

Step-by-step correction:

1. “barney” → “Barney”
→ Names should be capitalized. So “barney” becomes “Barney”.

2. Missing period after “He is a mini schnauzer”
→ The sentence “He is a mini schnauzer, and is the best dog in the world.” is actually two ideas joined incorrectly. But let’s look closer:
Actually, the first sentence ends at “barney” — so we need a period after “Barney”, then start a new sentence:
→ “I love playing with my dog Barney. He is a mini schnauzer...”

Wait — that means there are TWO errors here:
- Capitalize “Barney”
- Add a period after “Barney” (because “He is...” starts a new sentence)

Let’s count them separately.

3. “mini schnauzer” → “Mini Schnauzer”
→ Breed names like “Miniature Schnauzer” are often capitalized as proper nouns. In this context, since it’s referring to a specific breed, we’ll capitalize both words: “Mini Schnauzer”.

4. “when he smells everything?” → “when he smells everything!” or “.”
→ This is not a question — it’s a statement. So the question mark is wrong. It should be a period or exclamation. Since it’s describing something fun, maybe an exclamation? But let’s keep it simple: use a period.
→ Change “?” to “.”

5. “once, he saw...” → “Once, he saw...”
→ “Once” starts a new sentence, so it must be capitalized.

6. “Chased” → “chased”
→ Unless it’s the start of a sentence or a name, verbs shouldn’t be capitalized mid-sentence. So “Chased” → “chased”

7. “but instead of running away the skunk sprayed him!” → missing comma before “the skunk”
→ We need a comma after “away” to separate clauses:
→ “but instead of running away, the skunk sprayed him!”

8. “That was funny?” → “That was funny!” or “.”
→ Again, not a question — it’s a statement. Should be “That was funny!” (since it’s exciting/funny) or just “.” — let’s use “!” to match tone.

9. “Good dog” → “good dog”
→ “Good” doesn’t need to be capitalized unless it’s part of a title or name. Here, it’s just describing the dog → “good dog”

10. Check if we have 10 yet?

Let’s list them clearly:

✔ Mistake 1: “barney” → “Barney” (capitalization)
✔ Mistake 2: Missing period after “Barney” → add “.”
✔ Mistake 3: “mini schnauzer” → “Mini Schnauzer” (capitalize breed)
✔ Mistake 4: “everything?” → “everything.” (wrong punctuation)
✔ Mistake 5: “once” → “Once” (capitalize start of sentence)
✔ Mistake 6: “Chased” → “chased” (don’t capitalize verb mid-sentence)
✔ Mistake 7: Missing comma after “away” → add “,”
✔ Mistake 8: “funny?” → “funny!” (wrong punctuation)
✔ Mistake 9: “Good dog” → “good dog” (unnecessary capital)
✔ Mistake 10: ??? Did we miss one?

Wait — let’s re-read the original:

> I love playing with my dog barney He is a mini schnauzer, and is the best dog in the world.

Actually, after fixing “barney” to “Barney”, we still have “He is...” right after without a period. That’s run-on. So:

→ “I love playing with my dog Barney. He is...”

So that’s two fixes already counted: #1 and #2.

But also — “and is the best dog in the world” — is that grammatically okay? Yes, but maybe redundant? No, not a mistake.

Wait — what about “schnauzer”? Is it supposed to be “Schnauzer” even if not “Mini”? Actually, dog breeds are typically capitalized: “Schnauzer”, “Labrador”, etc. So “mini schnauzer” → “Mini Schnauzer” is correct.

Another possible error: “His favorite thing to do is to go on walks when he smells everything?” — we fixed the ?, but also — “when he smells everything” might be better as “while he smells everything” — but that’s style, not grammar. Not a required fix.

Wait — let’s check the last sentence:

> He earns a treat every time because he is such a Good dog

We fixed “Good” → “good”

Is there a missing period at the end? YES!

The whole paragraph ends without a period.

→ Add a period at the very end: “...such a good dog.”

That’s our 10th mistake!
