These just came in today! I’ve been waiting for the washing machine cleaner to be back in stock for me to place an order. If you have pets, this helps cut that oil and dander residue left in your machine.

✂️🥜🐶 WHAT IF WHEN YOU SPAY OR NEUTER YOUR DOG MATTERS JUST AS MUCH AS WHETHER YOU DO IT?

Preventing unwanted litters matters. But is it time to rethink HOW we sterilize dogs? Hormone-sparing procedures, including hysterectomy and vasectomy, can prevent reproduction while preserving natural s*x hormones.

🔬 NEW 2026 PEER-REVIEWED RESEARCH

Over 10 years, researchers reviewed records from 56,254 veterinary patients, including 313 dogs with mast cell tumors and 638 tumor-free comparison dogs. The study was accepted for publication in The Veterinary Journal.

🤯 1. TIMING MATTERS!

Dogs spayed or neutered before age 2 had 343% higher odds of a mast cell tumor diagnosis compared with intact dogs. Dogs sterilized after age 2 showed no statistically significant increase.

🐕 2. SIZE MATTERS!

Compared with small dogs, medium dogs had 2.6 times the odds and large dogs 5.2 times the odds.

⚖️ 3. WEIGHT MATTERS!

Overweight dogs had 80% higher odds than dogs at an ideal weight.

🧬 4. BREED MATTERS!

Compared with mixed-breed dogs, American Pit Bull Terriers had 7.5 times the odds and Boxers 3.9 times. Some breed groups were small.

❤️ 5. WHAT ABOUT SURVIVAL?

Neutering status wasn’t significantly associated with survival after surgery. Tumor grade and size were more important predictors.

🔬 WHY MIGHT HORMONES MATTER?

S*x hormones influence immune function and development. Researchers propose that early hormone removal and changes in luteinizing hormone (LH) may play a role, but this remains unproven.

🐾 THE BIG TAKEAWAY

Preventing unwanted litters doesn’t always mean removing hormone-producing organs. It’s time for individualized conversations with veterinarians about WHEN and HOW we sterilize dogs.
