When evaluating the health of pets, what is a crucial symptom to monitor in potential toxicity cases?

Monitoring for hematuria, which is the presence of blood in the urine, is particularly important in cases of potential toxicity in pets. This symptom can indicate damage to the urinary tract, kidneys, or bladder, and may arise due to various toxic substances or medications that affect the renal or hepatic systems. Hematuria can point to specific types of toxins, such as those affecting the blood or causing internal bleeding. Recognizing this symptom allows for prompt veterinary intervention, which is vital in managing potential toxicities effectively.

While fever, severe itching, and weight loss can also be significant symptoms, they are generally less specific in indicating toxicity. Fever may indicate infection or inflammation, severe itching likely relates to allergic reactions or dermatological issues, and weight loss may occur due to a variety of chronic conditions or malnutrition. Therefore, in the context of evaluating potential toxicity, hematuria stands out as a critical symptom that requires immediate attention.
