Puppies love to chew stuff, she did some damage when she was a puppy. My birks are hurtin. She has gotten better but seems to selectively chew parts of things that really suck. I am no fan of my hair. I love to wear a hair helmet and a certain style of Jager hat fits the bill for me (he he, bill). She chews out just the strap that adjusts the size. Good thing ebay seems to have them often.
Then instead of chewing up my shoes she just pulls out the insert and shreds them. I have had to get some replacements from the store. At least she does not do any more damage. My pinball machines are one of the few safe places to store stuff.
