My dog has chewed through my wires on my unit that turn on my fan at the ac unit. This is not the first time. Its always been an easy fix until now. He actuall pulled the wire from the unit and I dont know exactly what wires im supposed to connect. The wires coming from the house are red and white. But when I take the plate cover off the unit… the only wires exposed are blue and yellow. Are the the correct wires? And what connects to what.????

Wire colors with HVAC wiring are non-standardized, so the colors themselves don't help much.
Your furance/air handler should have a control board with terminals labelled R, W, Y, G and C. There should be an existing wire that connects to all of these (though maybe not C) that goes to your thermostat.
If anything is different in your setup, please update your question with a picture explaining, don't just wire it as I described or you may damage something.
The A/C unit wires connects to Y and C (usually white on C, but it doesn't really matter).
For reference:
Since this happens a lot, I'd also highly recommend putting some mechanical protection on this wire. Since it's already disconnected, it should be easy to fish through now.
Some flexible ENT tubing might be the easiest option:
1/2" rigid PVC conduit could also work, you can get elbows and other connectors.
All of this should be available at your local electrical / big-box hardware store.
