‘Puppies need more attention.’
Rewrite the sentence without changing its meaning beginning with:
‘Puppies don’t….’:

Hint: Negative sentences are typically formed by adding the word "not" after the helping verb. So, to keep the meaning intact, we must figure out the opposite of the adjective in the given sentence.

Complete answer: We can change affirmative sentences to negative sentences without changing the meaning of the original sentence.
A negative sentence has a negative word like, 'no', 'not', 'never' before the verb. Alternately, it has a negative noun like 'nobody' or 'nothing'. As the meaning has to remain unchanged, we must remember to modify the verb, which has a meaning opposite to the original verb.

Look at the following sentences for example:
-I missed the bus.
-I could not catch the bus.
Both these sentences have the same meaning, however, one is positive and one is negative. This means that the first sentence has the opposite verb of the second sentence to help it retain the meaning. The verb ‘missed’ has been changed to ‘could not catch’.

Let us look at another example:
-Rina is as tall as Binita.
-Binita is not taller than Rina.

Both these sentences have the same meaning, one is positive and one is negative. In comparison, we change the degree of the adjective as well. So, the first sentence has a positive adjective and the second has a comparative adjective. The adjective phrase ‘as tall as’ is changed to ‘not taller than’.
Now, let’s look at the given sentence:
Puppies need more attention. This sentence is self-explanatory. So, all we need to do is add a negative word and find the opposite of the given adjective. The correct negative to use would be ‘do not’. The opposite of ‘more’ is ‘less’.
So, the sentence will be written in the following way:
Puppies do not need less attention.
