It was diabetes with my dog, but three years later (he's twelve now) he has insulin injections twice daily, and is really healthy and happy, he still enjoys his walks, his medication isn't very expensive, he needs check ups at the vets evey six months minimum, but he's fine, if we hadn't found the probelm when we did, he would have probably died, so get it checked as soon as possible, you do have to wait about 7 - 10 days for test results, so really the sooner the better........welsh
