What is the toy in the far right bin? It looks like a barbell.

Every time I give it to my pet, he gets sick and it takes hours for him to get well again. He's been sick longer than he's been healty. I'm afraid he'll die before he turns 1.

I think you are talking about the MEDS. These are normally given when your pet is sick. I haven't played with LPP too much, so don't know if it is normal for the pet to get sick if MEDS are given when healthy though

That's meds? What's the thing between the ball and the ducky then? I thought that was the meds. No wonder he won't get well

Oh my God it's a BONE! I've been bonking my pet with a BONE all night! I thought I was giving him meds. I'm such a moron.
Perhaps some screen shots with close ups of the bins and descriptions of what each item is would have helped me.

The help with the game, does talk about what each thing does, so may help, otherwise have a look at http://www.ldw.com/instructions/lpp_instructions/index.html
There are pictures there, and more explanations. Hope that helps
