first things first
WELCOME ZIGGIE AND KRYSTLE
At three months of age, what you are expreiencing with Ziggie is not aggression, but just over zealous play. From his point of view, your fingers ARE the absolute best chew toy. They have the feel and taste of what represents the center of his life -- YOU.
. Remember, you have a terrior on your hands, a mighty hunter in the making -- be patient and redirect him with a toy or a chewey. I use BullySticks that I buy from a vendor on ebay --
eddieb260. The product he sells was not involved in any of the recent recalls.
For whatever reason my dogs shred the pads that contain baking soda. You might try the washable pads many of us buy from Valethics
http://www.valethics.com Very reasonable prices (I buy the "reclaimed" pads) and fast service!.
