I think everyone has their stories to tell on what their puppy has eaten over time!!
I never crated any of mine, just restricted them to one room, for damage limitation. Even then, walls get chewed, doors scratched, table legs eaten.........................it's just a fact of having a puppy, and when hes all grown out of it, you will look back and think its funny, honest!!
My first cocker - Chewitt - started in the car on the way home, hence his name, he had all sots of things in his first 2 years, electric razors, wedding photos, the front of OH car stereo, floor tiles.............................
