Well, another month has gone by. We're going to the vet tomorrow evening for another lupron shot. Unfortunately there is NO hair growth. So the lupron/melatonin combination is not working for Sebastian. In fact, he's lost so much hair now that he as a "bare bum"!!! If it were possible I'd gather up all of the dog hair from the floor (as we are in serious shed mode) and paste it to Sebastian - No I would never really do that!!! I just feel so badly for my little furless boy. Good news is that the benadryl is working and his mast cell tumors are gone. Not sure where we'll go from here with him. He's a sweet boy and I love him with all my heart. I think he knows this cause he's sure been dolling out the ferret kisses to his mommy lately. Anyways, just wanted to update his condition for those that are interested.
