Many animals enter shelters in poor health, malnourished, stressed and with no history of vaccination. Some animals will already be shedding various harmful pathogens, with or without showing any signs of disease. With all this disease around and so many opportunities for transmission, one might think that ubiquitous disease spread is nearly inevitable.
However, there is reason for hope. Even if infection control is less than perfect, we can support animals’ own immune response through attentive vaccination practices, daily monitoring, stress reduction, wholesome food and clean water, and other measures to support well-being.
