Dose may be adjusted based on clinical response and regular veterinary monitoring of electrolytes and kidney function. Always provide access to fresh water during treatment.

Precautions:

• Do not use in dehydrated animals or those with severe electrolyte imbalances
• Use with caution in diabetic or hypotensive patients
