I am sorry to hear you are worried about Buster.
My name is***** am a veterinarian and will do my best to help.
Can you tell me more about what the slight kidney issue was on the blood tests? If he is drinking more water than usual, I would want to know as much about his kidneys as possible.
Shaking like this can be pain, weakness, or a neurologic condition ( brain tumor, inflammation, infection of the central nervous system), or an electrolyte imbalance (sodium, potassium, chloride which were probably checked on the blood tests).
Is the shaking constant? Does it stop when he sleeps? Is it worse when he tries to walk or move?
Tremors can be an indication of many conditions. If the blood tests are normal ( it would help me to know his BUN, creatinine, phosphorus, red blood cell count, and electrolytes and the results of a urinalysis to know more about his kidney condition), and especially since he is not eating very well, my next step would be an ultrasound of his abdomen and internal organs.
There are some conditions that cause tremors that are seizures, but then probably the tremors would come and go.
Stroke is hard to prove, unless you do things like CT or MRI scans. However, most dogs with stroke have high blood pressure, and this is easy to check. If his pressure is high, then medication may help.
I hope you can see what I am writing!
I will try to contact you in another format, if I do not hear from you.
This could be so many things. I am worried about the increased drinking, weight loss, and poor appetite, as well as the tremors. If this were my own dog, I would continue to do tests (urinalysis, ultrasound, blood pressure) until I found the cause.
Buster has had the shakes for some time approx 4 years , the yearly checkup suggested it was muscle wastage - Re kidney issue we didnt get futher info other than it was put down to his age and he has lost a kilo over the last 6months - 10.3 kgs down to 9.3 kgs .
Over the last 2 weeks he has gained weight due to type of food (Human Grade) he is now 9.45kgs .
To us he seems to be closing down - 15 is a grand age .
We dont believe in prolonging his life with medication - Steriods were suggested by the vet which we disagreed with.
If it was something viisble eg last year Buster had bad breath , diagnosed 3 bad teeth which we had removed . This didnt affect his abilty to chew dried food .
It is possible that Buster is Milking the situation re hand feeding? -To prove this how long can we leave Buster without encouraging him to eat ? leaving food available in his bowl. He has water available all the time and is drinking approx 400ml a day, which on reflection doesnt sound a lot
Hi many thanks for your advice , we will ask for further tests . The blood test was 2 weeks ago when he had the shakes from head to foot . Incidently just remembered although the vet suspected a stroke a friend said his dog had the same issue and that was diagnosed as an epileptic fit
Hi, many thanks for your help. We had a urine test done and have just got the results. Confirmed kidney failure + high protien detected. Buster will be put down tomorrow morning. Currently he is refusing food totally and not drinking.
Many many thanks for your input.
