i beleive it is a disadvantage as a dog uses its ears when travelling, i believe they use their ears when marking at an entrance too sometimes. Although it is a disadvantage, if the dog was a goodun im sure it would adapt its nose to suit. Culling is great when you have a few pups/litters available in the near future, but if this is your only pup available, id take a shot as long as your not planning to breed from it. I definitely wont be breeding from it but if it wants to work ill work it and see how it goes. I wasn't even looking to get another terrier until I got a text asking if I knew of
