This is my first time on this forum. Our 9 yr old boxer has started drinking an excess amount of water also. We also took him to the vet where they did 2 urinalysis and two different blood tests. All came back OK. The only thing they saw was that his Valley Fever seems to be coming back ever so slightly. He has been on anitbiotics for 1 week now and I do not see any improvement. His appitite is still good, however the vet would like him to lose anywhere from 15 - 20 lbs. He had Valley Fever when he was younger and was antibiotics for a couple of years. I do not remember this being a sympton back then.
What do you think? The vet wants to wait a couple more weeks before he examines him again to give the anitbiotic time in his system.
