So a long post my next door neighbour has recently moved in to the house next door and he's got two pit bull cross XL Bullies now these two dogs are already huge! We have a little dachshund, anyway the two dogs have been digging under the fence to get to my dog when he's out in the garden, anyway this morning the two dogs was in my garden running round so went round to next door asked him to get his dogs and can he sort under the fence out he told me they only want to play with my dog, now I've seen these two dogs left fighting with one another in the garden and the noise and the growls from them really don't sound nice at all, I'm just worried if they get into my garden while my dog is out, what can I do to protect my dog in his own garden?
