Hi folks,

I have a 13 year old boy that has always been very healthy, however in the last two weeks he has gotten sick. The symptoms are: loss of appetite, trembling, and high water intake. My vet did a complete blood test and found nothing that stood out. He has lost almost four pounds and I'm starting to get very worried. Any input would be greatly appreciated.

what about an urinalysis? or xray to rule out an impaction or blockage in the GI tract….It is sad when our pals get older, we still worry about them as children....it is very curious that the blood work did not show anything. Maybe you can ask the Vet for some more tests, another Vet for a second opinion. Strange things could have happened to the blood work, mixed with someone else, a false positive for what ever reason,...I would not accept the diagnoses of "nothing wrong" if he was my boy! could he have possibly gotten into chocolate candy, any dangerous cleaning solution, or anything???? just some ideas..............go to petmd and click on the symptoms you describe. maybe something will jar your memory of something he got into....? PS: {I just went on the site and clicked the symptoms you described, here is what came up: (regular blood tests wont show cancer)}

I agree with Buddys Pal… if they didn't do either urinalysis or xray, I'd get them done. If you have a sick dog and the vet just sort of says "oh well, blood work looks okay".. may be time for a new vet. Something is obviously wrong.
