Answer:
Dogs are the best type of pet. Most dogs are easy to take care of, they are fun to be around, and they are always happy to see you.
Step-by-step explanation:
The best type of revision to the sentence(s) above is the aforementioned one.
The un-revised version is "Dogs are the best types of pet most dogs are easy to take care off their fun to be around and their always happy too see you."
We can see here that this was not properly punctuated which makes reading it erratic, and understanding it quite difficult.
To properly revise it, the use of the punctuation comma and periods(full stop) were necessary. Also the capitalization of the first letter after the full stop was required.
