Oh, poop

Sam's and Bodega all have the classic "poop" bags. We have large dogs so we go to the plastics store, P l a c e o (spaces because editor won't allow the word), and get the mini's. Biodegradable, one kilo is up to 35 pesos and lasts us over a month. Not bad with three big dogs.

Rawhide chews at all the grocery stores, for fancy stuff, look on line at Petco.

Not sure why you couldn't use Placeo, but we also use biodegradable plastic bags bought at Zihuatanejo's Mercado Municipal.
