Hi, thanks for caring about them and the great tips. I searched and searched and never did find that hook. I was a nervous wreck to sleep last night not knowing if one of them would get sick. However, everything is normal around here. I have three dogs but my two yorkies are the only ones that would bother the tree. Snoot is a pekingese (almost 12 yrs) and has never ever botherd anything in the house. The girls are fine and I even checked their poo poo and saw nothing?? I know I'm going to see some plastic at some point today. Anyways, thanks for being so nice. I really appreciate it.
