Leg holes for dog sweater

[Rala Diakite]

I'm a beginner crochet person.  I chose the simplest dog sweater pattern I could (yarnspirations BERNAT crochet dog coat BRC0713-011004M)), but the leg holes are killing me!  The pattern says : All leg sections are worked at same times using separate balls of yarn for each section.

I didnt find the pattern that matches but this one has the same instructions " sections are worked at same times using separate balls of yarn for each section."

Download the pattern and look at the photo of the sweater laying flat with the leg holes.  Pattern is telling you you are working in rows but you have to do something different because of the holes for legs.  You will be working in sections back and forth in rows so you will need a separate ball of yarn to work that middle section between the legs until it reaches the point that you end the holes and are able to go back to working the row that goes completely from one side to the other side.
