Keith,
I'm no expert either but was in a similar situation. Here's what I did (not sure if I was right or wrong). Last weekend rain was in the forecast so I fertilized my front yard and kept the dog strictly in the back. It rained and the fertilizer did whatever it does and was gone. Looks like more rain coming this weekend so I plan to do my backyard and let my dog use the front until it has worked its way in. My dog likes to eat the grass on occasion so that has been a concern.
