I have a female 25 week old GSD. She is starting to get out of line, she still obeys. However, she's starting to chew really bad. I have her toys, & bones. Its not like she doesnt have anything to chew. She also has been digging here lately. I look at there is big holes through out my yard! I also put a bag of soil in thr yard & went working on the yard. When I turned around she had chewed and dug through the bag. She also has chewed a couplr hundred dollar part that I had. Is there anyway to help this situation?
