There's a guy I know with two dobes. He emailed me yesterday and told me that both of them were eating the plastic trays that are in the bottom of their crates. He said that they had been throwing up pieces of it. He also said that he put a piece of plywood down in his boys crate so it would take him longer to eat it, YIKES! I told him that could be very dangerous, and I suggested he get a chew proof bed to go in the bottom of the crate, or maybe a thin sheet of metal with lost of blankets and a pad on top of that so they maybe couldn't chew it. I also asked him if he put frozen kongs, or other stuff that is SAFE for them to chew in it. He said that he only puts rope toys in them, and they unravel those. He said he would check into the chew proof beds. I asked him to keep me updated. I have no idea how much these dogs are excercised, so I'm not sure if it's due to boredom from not enough exercise or what. I'm assuming that it's either that or separation anxiety. I know that he works full time and is pretty busy. I don't know him very well, we only met at an obedience class, so I try not to be too nosey when I offer suggestions. I was just wondering what some of you guys thought or if you had any other suggestions that I could tell him about?
