So, here is an update, I cut open one of the toys and there is no bell, I thought it was a bell based on the sound. It is a fur covered ball of rubber or plastic and little tiny stones inside. The dogs have a raw food diet so these tiny stones aren't going to do anything. Also, it has been three nights and dog is not under any duress, he is eating, drinking, peeing and pooping!
Today he ate part of my dad's slipper and the other one was chewing something shiny, turned out to be my mom's earring and she didn't even notice the dog pulled it out when she was licking her ear (dog, not my Mom - ROFL).
So, I'm just not going to worry about this at all! Stupid Dogs is all I have to say.
Thanks for all your advise, encouragement, discouragement, so on, and so forth!
I will advise DS and DDIL to leave vet information and a credit card for charges for future animal sitting adventures.
The cats are just so easy other than the standoff this morning when their cat kicked my cat out of the spot she has claimed - never a dull moment!
