Good luck! Welcome to puppy love...almost!
Check with your vet for the bad news plants.
Is this your first puppy? Most out grow the habit but you must be firm with the pup to gain control. They are mostly bored and are teething. Go to the farm and ranch store or a pet store and buy some "hoofs" for the pup to chew on. My pup likes to chew on my wooded porch rocker rails. I put Tobassco sauce on it...no more chewing there and left the whole rocker alone.
My pup is now 9 mo old and almost have all my plants back.
