**Magnesium sulfate** (Epsom salt) is often used at home for soaking sore paws or treating minor localized swellings. * **Topical Soaks:** Dissolve the recommended amount in warm water. **Do not let your pet drink the soak water**, as it can cause severe diarrhea and potential electrolyte imbalances. * **Oral Use:** If prescribed as a laxative, expect your pet to have loose stools. Ensure they have constant access to fresh drinking water to prevent dehydration. * **When to Call the Vet:** Contact your veterinarian immediately if your pet becomes extremely lethargic, weak, has difficulty breathing, or collapses.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.
