I am having the same problem with my two.....7 and 8 months old. They eat EVERYTHING or try to!!!!!!! Paint, wood, base boards, wallpaper, dryer sheets, puppy pads, phone cords, feathers (from my pillows), and Jax started eating poop. They have both been to the vet and have had blood work...for other reasons...and everything was normal. The vet said that they are like babies...they put everything in their mouth whether it tastes good or not
