I have two Tibetan Mastiff pups (7 months old) – since bringing them home aged 12 weeks they have continuously searched out wood to eat in the garden. If I take them in the woods they are constantly munching on sticks. Does anyone else have a similar problem and if so, does anyone know why??? I’ve asked all of my doggie friends and no-one can seem to come up with a conclusive answer. Thanks, Lisa :help: http://www.completely-canine.co.uk
