Right terrier men me mate has a dog we have dug to this dog 4 times very sensible decent dog dog . Last 2 times we have been out he going to ground but not finding . No either there nothing at home or on worse senario he could be jacking wich would be a crying shame .. But tbh i dnt think he would go down if nothing in there Then again could be wrong .. Anyone else had this happen to a dog that they have dug to before
