Hey guys, my dog Schnapps is now 15 weeks old. He has a wonderful temperament and is great with everyone. Recently however we have noticed him becoming agitated and aggressive toward anyone who attempts to fill in or even approach the few holes he has dug in the garden! He has not buried anything in these holes and they are quite small. If he becomes aggressive I tend to distract him but he still remains anxious if people approach what he has dug. My question is whether or not this is the beginning of a serious issue or just normal puppy behavior?
