Hi and welcome to you and your boy!

Sorry for the reasons you're here but glad you found us. It sounds like your boy may have Calcinosis cutis. Was a biopsy done on those hard lumps? Our resident expert on Calcinosis cutis, Renee, has pictures of her dog showing the Calcinosis cutis, here is a link to her album: http://www.k9cushings.com/forum/album.php?albumid=805 Could you take a look at those pictures and let us know if this looks like what your boy has?

To enable us to provide better feedback we need to know more about your boy. What tests were performed that diagnosed the Cushing's, and could you post those results? Was a CBC/chemistry blood panel done recently, and if so, could you post anything that is abnormal with the reference ranges and units of measurement...e.g...ALT 150U/L (5-50)...thanks. How much does he weigh?

As far as the physical activity, I believe continuing with it is ok as long you let him be the guide to how much is done.

Concerning the diet, there really isn't a "set" diet for a cushdog, it should be tailored to that individual dog's needs. However, because of the effects of excess steroid on protein and fat metabolism, a good quality, moderate to high protein, low fat diet is recommended.

Please know we will help in any way we can, and do not hesitate to ask all the questions you have.

Hugs, Lori
