Leptospirosis in dogs progresses through incubation (days to weeks), an acute phase (fever, lethargy, vomiting), an immune phase (body fights infection, potential clearing or worsening symptoms like jaundice, pain), and potentially a chronic phase with lasting kidney/liver damage, with early treatment crucial to prevent severe organ failure, requiring immediate vet care if suspected.

Can dogs get Lepto from eating grass?

Yes, dogs can get Leptospirosis (Lepto) from eating or licking grass, dirt, or puddles contaminated with the urine of infected wild animals like rats, raccoons, or deer, as the bacteria live in moist environments and spread through urine.
