Dear all, I'm a veterinarian graduated student in Chile, and i would like to borrow a space here to ask for any kind of advice if it's possible. A sea leopard (*Hydrurga leptonyx*) is stranded in Talcahuano (VIII Region of Chile) and here are a few volunteers taking care of this animal. It seems like the sea leopard has pneumonia, a fracture and some injures on its tail. For the treatment, i was thinking of: *Acetylcistein*: 20% solution nebulizer BID-QID *Aminophylline*: 5,5 mg/kg PO, BID I don't know if the doses would be fine to a sea leopard. I'm very far from this animal, because I’m from Santiago. But i a veterinarian already have diagnostic the animal. I don't think they will make a cultive to see the agent. But, would you treat it with antibiotics also? Which would be the best for this seal and which dose? I read that parasitism is a very common cause of pneumonia in pinnipeds. Would you treat it with Fenbendazole also? (11 mg/kg PO SID (two doses)) If anyone could give us some information we will be very grateful. Thank you! *M.
