Most puppies like to chew shoes or furniture and so on but my dog has thing for cash money. we keep missing $ and finding it in his cage.last month he dug up a coffee can with 830.00 in it just off a bike path. l guess we need to keep him away from the bank and atms for that matter. we no longer keep cash where he can reach it, however ,wherever we put it he seems to zero in on. we love him despite his weakness for our cash.
