New Seed, Existing Lawn and Pre Emergent

I need to patch some area's in my yard that have been impacted by my dog. In some area's, i need to put down some topsoil to even spot out, then i will put down seed, fence off and water. However, around the same time, i am also supposed to put down the "step 1" from Scott's that has the pre emergent.

It is my understanding that if I put this down over the seed, it will cause the seeded area's not to grow.

So, do i just not do this in my back yard to be safe, do it in the are's that will not be seeded, or something else.

THanks in advance for your recomendations!

Correct...preemergent fertilizer stops seeds from germinating. Wait 6-8 weeks before trying to seed. If you get little rain, you might need to wait longer.

I have also done both making sure to keep the fertilizer clear of the newly seeded area, but it's kind of a pain.

What are you trying to prevent with the pre-emergent. Could you skip it and approach the problem with a post-emergent herbicide after the seed is established?
