I am a Texas Residential landlord, tenant has pet and is not paying pet deposit: 3 day or 30 day Notice?

I have a Residential Hud Tenant whose security deposit was pro-rated and she has not paid AND she has a dog and has not paid a pet deposit. I want to serve her with an eviction notice: what form do I use.."Notice to Vacate" - 3 day notice or a 30 day notice? These items are a breach to the rental agreement.
