I have a 6 month old Cardigan Welsh Corgi. He eats/chews on everything!!! I made the mistake of leaving him out of his crate while I was gone. He scaled the back of the couch, got on the kitchen counter and found a highlighter. He was considerate enough to take it to the floor and not ruin my new sectional. Did you know that highlighter is not permenant and comes up with a carpet cleaner. I will note not to leave any cycling clothes, especially shorts where he can get to them. Sorry about your short, but your puppy is cute!!
