My Dog Needs to Stop Nursing—Is Epsom Salt Safe?’
You’ve weaned the puppies, but your dog’s milk supply won’t slow down. Maybe you’ve heard about using Epsom salts to dry up milk, but you’re worried: “Is this safe for my dog?” Let’s separate fact from fiction.
While Epsom salts can help soothe swollen mammary glands, they won’t directly stop milk production—and misuse can harm your pup. Here’s how to ease discomfort and reduce lactation safely, with tips from veterinary sources.

How Epsom Salts Work (and What They Don’t Do)
Epsom salts (magnesium sulfate) are often used in warm compresses to:
Reduce swelling in inflamed mammary glands (mastitis).
Soothe discomfort from engorgement.

Step 1: Make a Vet-Approved Epsom Salt Compress
Mix 1 tbsp Epsom salt in 2 cups warm water.

Pat dry to prevent moisture buildup (which can worsen infection).
Step 2: Pair With Gradual Weaning
Slowly reduce puppy nursing sessions over 7–10 days.
Feed puppies separately to decrease milk demand.
Step 3: Watch for Mastitis Signs
