shock lung/ exertion injury in dog?

I had orally dosed glucose and he had eaten a tin select protein and A/D on initial presentation as my initial concern was glucose and fatigue but the crash collapse with dyspnoea came after this when the muscle tremours, gagging, breathing issues and collapse started and then the bloods came back normal for all electrolytes including calcium so I was then looking for other DDs.

Only on day 2 did I go with trying high Ca (or other untested minerals present in the milk replacer) and the response wasn't subtle - it was obvious - something had suddenly improved and the resting symptoms of itching face, sneezing, tremours, paraphimosis which had been present the whole time resolved completely

[quote user="Gillian Mostyn"] Surely the response to feeding is just as likely to be a response to glucose or something else as it is to calcium?[/quote] I wonder what the pup was being fed on at home - some unbalanced BARF diet or some such? Richard?

mystery solved - is a Ca / mineral imbalance.

Is this a real condition?

Glad I'm not the only one who didn't 'get it'. Surely the response to feeding is just as likely to be a response to glucose or something else as it is to calcium?

I know was left feeling pretty puzzled as well, especially when left with the feeling if I had just tried that at presentation the night before...

Case of treat the patient, not the lab machine?? The response was obvious and dramatic - pup was doing somersaults and howling with normal energy levels within an hour so while the Ca measured was fine, something in the whole mineral imbalance thing was obviously out. Don't know much about magnesium in dogs or any of the other muscle related micro/trace elements but whatever was causing the deficiency was restored by high Ca milk replacer.

Anyhow now know quite a lot about juvenile cardiomyopathies, German shorthaired Pointers and genetic disease, pulmonary hypertension, toxins caused by fungi and spoilage...

Tested Ca levels 2.53 (1.95 - 3.15 nmol.l) but after 1 hour of being fed welpi & A/D we have a dog now bouncing up and down, howling with energy, not a tremour, no sign nose irritation, none of symptoms of 2 hours ago. Just been pulled around the building - no recurrence of signs

Exertional rhabdomyolysis? I know you said no myoglobin in urine, but would this appear straight away?

[/quote]Mitochondrial disease or Myasthenia Gravis? Can't see it will be hypocalcaemia it would not wax and wain that quickly with no specific therapy but why wait for ionised calcium just run a total calcium in-house.

Maybe it has panic attacks associating the cold air with its bad experience?

Weird.

next update - so having sat in a kennel with minimal signs, sl tremble and paraphimosis, we took him for a walk outside, cold air etc. Within seconds sneezing, miotic pupils, tremours down face, limbs, gagging so back inside with itching face/ nose and again as he warmed up, pupils back to normal, recovering again within minutes. Makes me think of hypocalcaemia and he is teething/ growing.

Think I will send a sample for ionised Ca levels

Top of my differential list would have to be toxin ingestion of some sort, illicit drugs maybe? cannabis? ecstasy?

ecg maybe?

I recall a case in an older Greyhound that had recurrent attacks similar to what you describe, that were increasing in frequency, although not the paraphimosis. Was eventually referred and found to have a brain stem tumour.

the speed things deteriorated was spectacular and I can follow the link of pulmonary/ cardiac/ cns but the puzzle is why paraphimosis?? Part of the brain injury? Circulatory pressure?

Was really hoping someone would pop up and suggest a toxin I have overlooked, never heard of or has 1 case described in outer Mongolia

First well done for saving its life. I really can't imagine why a fit young dog would have any issues from running around in the cold for a few hours especially as its temperature was normal on admission and its glucose was normal. I would vote for some sort of toxin but am no wiser than you as to what it may be. Not the time of year for spraying insecticides in the field I would have thought, but may be worth asking the farmer. Owners aren't pot heads by any chance?!
