Barkley has made it to the ripe age of 11 1/2 but now we are at a crisis situation. It started with a limp that came on suddenly and was accompanied by shivering or shaking. I took him to the vet right away and two things were discovered, and infection in the form of bacteria in the urine and an ultrasound that revealed irregularities in the appearance of his spleen. The blood work showed normal levels for blood cells and platelets. There were some elevated levels for kidney and liver, but if I understood the doctor correctly it didn't indicate anything specific. They sent me off with two kinds of anabiotic's, and antinausea medication and nutraceutical product to support the liver. That was last Wednesday. I missed a vet appointment on Friday morning because I don't sleep for fear that Barkley will choke or stop breathing. They were unable to reschedule until Monday, which would be tomorrow as I am writing this. The big problem is that Barkley stopped eating as of Saturday morning (yesterday) and only had a light meal on Friday night when he was already turning away from a lot of his normal food. For the last five days, he has been very weak in his legs and seems to be getting weaker. He's very shaky when he's standing and is too weak to get up off of a smooth floor. He's also been losing weight, having lost 4 pounds just last week. His average adult weight is about 85 pounds. He is down to about 70 right now. I called the vet on Saturday morning, yesterday, and they told me to take him off the amoxicillin. They said that his loss of appetite may be due to amoxicillin, which could be upsetting to his stomach. It's been 24 hours and there's no sign that his appetite is returning. I won't get into the vets office for 24 hours more. Is there something I can do to get some nutrition into him. He drinks water with no problem but turns his nose away from any food. away from any food. He's drinking a lot and urinating frequently and so I'm worried that just plain water might leave him short of electrolytes, so any ideas about that will be welcome too. I should also say that he moves from looking like he might expire at any minute to looking fairly alert and happy.
