How come my dog never plays with her toys?
We buy her all kinds of stuff from bones to balls so she won’t be bored. The only thing she plays with are some old bath toys I used to use. The are like 3 years old and I don’t like seeing her play with them. She plays with them every now and then but never her other toys. She only plays with her rawhides. She doesn’t look at those other toys twice. She has this thing for pencils though.

Dogs don’t need ‘stuff’ – they need interaction.
It sounds like she needs a friend, or some socialization.
Try signing up for an obedience course, and making some friends while you’re there. Perhaps she coudl sue a playdate, or even another dog in your household. Ask the trainer to help assess what her deal is.
Some dogs just don’t do the toy thing, and need other dogs to have a good time. She sounds a bit bored, and it also sounds like her tummy might be bothering her – eating things like pencils is often a sign of a gastric problem, or even a food allergy.
