1439. A 10-year-old Schnauzer has fits and collapses suddenly

May 29, 2013

"Do you remember you operated on his ears?" the mother and daughter brought in a white Schnauzer that had fits and collapsed just over one hour ago. The dog had white and cyanotic tongue and was breathing fast. I put him on oxygen therapy first as he had insufficient oxygen for his red blood cells, leading to purplish tongue and mucous membranes.

I reviewed the medical records and said: "Yes, he had very painful and itchy right ear and his ear canal was opened up. How's the ear?"

"No more problem," the mother said. "Could the dog be suffering from a stroke?"
"Hard to say at the moment, I need a blood test and examination. It is possible there is a brain abnormality e.g. tumours, infection or bleeding or a systemic infection. I advised a brain scan but that would be costly and so the owners wanted the basic treatment to be done. That included a blood and urine test.
The veins were collapsed too. Dr Daniel had to collect blood from the jugular vein. It was not a good sign. Despite intensive treatment, the dog passed away 2 hours later. 

Significant findings are:
1. Total white cell count 18.3 (6-17). N 90% Absolute 16. L 9% Absolute 1.7
2. Red cell count 5 (5.5 - 8.5)
3. Haemoglobin 11 (12-18).
4. Platelets 108 (200-500). Few giant platelets present. No platelet clumps.
5. Uric acid  0.27 (<0 .13="" br=""> 6. SGOT/AST 129 (<81 br=""> 7. Urea 3.4 (4.2 - 6.3). Creatinine levels were normal. 
The blood was taken from the jugular vein. The dog had around 30 minutes of oxygen therapy by mask before the blood and urine were collected.

pH 5.0 (5-8), SG 1.020 (1.005-1.030), urobilinogen +, blood 4+, bacteria 3+, white blood cells >2250, red blood cells 315.

It is important to practise evidence-based medicine. In this case, the dog could have a septicaemia. There could be a pathogenic type of bacteria picked from sniffing the grass or consuming some poisonous food or treats.

The onset was "sudden" fits and recumbency. There could also be an internal bleeding and breakdown of capillaries. A post-mortem may give a definitive diagnosis as to the cause of death. As it would be costly, this was not advocated by me.

A simple blood and urine test provide some clues of illness at the most economic rates as compared to brain scanning and more tests. In any case, the dog was breathing fast and had white and purplish tongue, indicating a very poor prognosis. However, other tests like brain scan needs to be advised. This Schnauzer has been well cared for as evident by his good size and body condition as so the death was a "sudden" loss to the family. No poisonous food or drink was consumed according to the mother.
