Mexico is full of dogs so no problem. You just need papers from a vet saying the dogs are healthy and shots are up to date. Exam has to be withing a few weeks of crossing the border.

So what do you want .. the east coast or west? I live on the West near Colima in southern Jalisco. No help with Yucatan or Gulf areas.

Bringing all your stuff without knowing where you'll be sounds like trouble. Either sell it or come and find where you want to live and go back for it. You can't avoid the import taxes without an FM3 visa (resident). You can buy everything here.

Most towns of any size have Telmex DSL that works well. My town of about 15,000 has it. Other larger towns may have Cable options
