I find the Greek Yogurt at Wal-Mart, the Oikos brand. They also carry it at Trader Joes.They have flavored, Bella likes the vanilla best.
The yogurt drops I find at Petsmart in the dog treat area.
Since her mouth surgery we have found she is CRAZY about cottage cheese!
She'll take this over any other treat. Since she's not lactose intolerant I give her a tablespoon once a day as a special treat.
Have a great day!
