Polycythemia vera, a rare disease/policitemia vera, una enfermedad rara

A 4 y.o crossed labrador presented after being vomiting and passing soft faeces since the day before. He is not himself, and nothing remarkable is found on his clinical examination. Initially, the case is treated as a gastric problem. However, 2h later he collapsed, and is hospitalized, giving fluids, and starts with mild seizures shortly afterwards. Now his mucose membranes are congestive, and on a blood test his hematocrit is extremely high. Even after 6h on fluids, his hematocrit stays very high.

Weird behaviour/ extraño comportamiento

(Photos from internet) An Englishman arrived late one afternoon quite concerned about his yorkshire strange behaviour.

His iris were wide open but they would respond to direct light by closing, he could hear us, his reflex were fine and all his propioception were apparently normal. Other finding that didn't make much sense was a slight low temperature. He just was unable to coordinate his movements, control his legs or keep his head up. His owner mentioned that his dog had been out in the garden that afternoon and then he became very drowsy.
