I am pretty sure that the yogurt stuff is awful for your bun so its a good thing she isnt eating them.
Use veggies as treats! Try giving her some cilantro or parsley or a leaf of bock choy, kale or collard greens. She should be getting these anyways as part of her daily diet but this way she will get a healthy snack!
You have to be careful about giving her treats. Sugary fruits can upset the delicate balance in their tummies and cause an infection among other problems that are potentially fatal! So just remember, one or two little bits of fruit are ok, dont over-do it.
With that said, my baby LOVES dried banana chips, apple chips and raisins. She also enjoys small slices of carrots and frozen strawberry slices or bits of frozen peaches. I view those as her “popsicles” they are a nice treat on a hot day!
Check out the BinkyBunny store, they have some sticks that Huckleberry went nuts over.
