 There are supplements that some Yorkies do well on like:
 Glucosamine for joints.
 Omegas with vitamin e for coat.
 Probiotics and/or enzymes for intestinal issues or just because (kind of controversial).

  I agree about the imbalance if given too much of. I forgot to mention I dont give mine hers every day. Sometimes she will just not bother to eat for 2 days when she is 100% healthy, simply because she is being picky and i find the one i give her helps her appetite 

 it's a low level vitamin - once this bottle is finished i doubt I will replace it in a hurry.
