My 13 yr old Cocker Spaniel has become ravenous, she has always had a good appetite, but now she literally pesters and whines for food, she is currently fed 4 times a day due to having Pancreatitis, but this hunger seem to come on fairly rapidly and it is driving me mad, at night she will whine and pester until its feeding time, and when she is eaten she still looks for other food and pesters for anything we have. She has had a blood test to look for evidence of Cushings or Diabetes, but nothing is obvious, I tried to ask the vet if there was anything else out of kilter that might point to something else, but she was a foreign lady and she didnt seem to grasp what I was asking. Topa is on Thyforon for her hypothyroidism , and had a slight increase in dose , I did wonder if it was that, but I am concerned it could be a tumour or anything, has anyone come across this and can give me some ideas.
