Addison's always a differential i include in acutely collapsed dehydrated dogs. sounds like a nightmare weekend kit wise!

Thanks, urinalysis will be useful as soon as I can get some, too tender to palpate bladder for cysto earlier but may be better now and may consider passing a catheter if not. Don't remember CK being raised but I'll review the results when I pop back in. Aggressive IVFT already started with high dose buprenorphine so I suppose only adding in diazepam would change, but its a useful differential to consider, and imaging will be performed as soon as possible (if still relevant then...)

Have you considered exertional myopathy (rhabdomyolysis) as this can occur occasionally in greyhounds and can appear as you have described above? Further diagnostics to confirm this disease would be urinalysis showing myoglobinuria and vettest creatine kinase would be very markedly elevated. Electrolyte and acid base analysis might show an acidosis and hyperkalaemia. Treatment would be supportive including fairly aggressive iv fluids (renal disease can be a sequale of rhabdomyolysis), strong pain relief and diazepam can be useful as a muscle relaxant.

Remember also that normal greyhounds will have pcvs in the 60's.

Could be something completely different of course, an abd rad would be very useful to rule out mesenteric torsion etc.

Good luck.
