That&#39;s interesting.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/203896?ContentTypeID=1Sat, 20 Oct 2018 22:24:13 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:8c10bf67-4080-4c3a-bae6-ef9089b0cf55Gillian Mostyn<p>If the dog is moving/agitated enough to make it hyperthermic, I&#39;d also probably be sedating/anaesthetising it.</p> <p>I suppose a toxin has to be on the differentials...mushrooms?&nbsp; Metaldehyde? Any chance of a head trauma? (Check for bruises). I have seen one case of sudden onset hepatic encephalopathy where a congenital shunt suddenly &#39;opened up&#39; when it was older.&nbsp; Otherwise a brain scan...?</p> <p>Odd one!</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/203895?ContentTypeID=1Sat, 20 Oct 2018 21:51:38 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:ccf0a8da-ad24-472a-858d-305d7248a17dSara Ramsey<p>*Toxoplasma...not toxics!</p><div style="clear:both;"></div>
