Our First Heat Cycles

When Luci was about nine months old, she became the first one to go through a heat cycle. Hers ran 3 weeks, from December 23 to January 12, and honestly, it was far more manageable than I expected. We used size‑small washable dog diapers from Wal‑Mart with disposable panty liners, and most days the cleanup was nothing more than a couple tiny spots.

Nighttime, however, was a different story. Luci quickly mastered the art of slipping out of her diaper in her crate — a true weenie

Houdini moment — so we eventually stopped using diapers overnight and just washed her blankets each morning. Her appetite dipped quite a bit during her cycle, so we supplemented with treats, veggies, cheese, and chicken, which she accepted with zero hesitation.

When Things Shifted

Weeks later, on March 2, Luci started acting… different. Not dramatically different, just noticeably off. She was:

• Whinier than usual

• Clinging to my side begging for belly rubs

• Or tucked away alone in her crate in our bedroom

That night, while rubbing her belly before bed, I felt her lower abdomen — firm, almost tense — and she whined when I touched it. Combined with her still‑low appetite, my mind went straight to the worst. I couldn’t even remember if she’d had a bowel movement that day, which didn’t help my spiraling.

In the morning, I called the vet as soon as they opened and they wanted to see her right away.

Before leaving the house, I took her outside to potty. She only peed, then immediately rolled onto her back for another belly rub. When I reached down, my hand came away wet. She was producing milk! Wait…what?!? What did I miss?

The Vet Visit That Explained Everything

At the appointment, the vet confirmed what I never would’ve guessed: Luci was experiencing a false pregnancy — a hormonal after‑effect that can happen 6–8 weeks after a heat cycle ends.

Suddenly, everything made sense:

• Clinginess

• Whining

• Nesting behavior

• Decreased appetite

• Firmness in the mammary area

• Milk production

It was a relief to know it wasn’t a blockage or an emergency. The vet prescribed antibiotics to prevent mammary infection and told us to ease up on belly rubs to avoid stimulating more milk production. We also had to keep her nipples clean, which she tolerated with her usual dramatic side eye.

Luci bounced back quickly and is doing great now. She’s eating her regular kibble again — and, of course, she’s always open to treats if anyone even thinks about offering them.

Can you see how swollen her mammary glands are?

Then Came Dolly

Dolly’s heat cycle arrived a few days after her first birthday and also lasted three weeks. And let me tell you — she had her own agenda.

She pulled the panty liner out of her diaper many times and would even just remove the entire diaper more times than I can count. Eventually, we ditched the liners altogether and just changed the diaper more often. It was a completely different experience from Luci, and a reminder that even in the same home, dogs handle their cycles in their own unique ways.

Now that Dolly is approaching her 6–8‑week post‑cycle window, I’m watching her behavior closely, just in case she follows in Luci’s footsteps.

Lessons Learned from Our First Heat Cycles

This was my first time navigating a heat cycle, let alone 2 that were had way different behaviors and I learned quickly that the small things matter. Subtle behavior shifts can be the earliest sign that something is changing. A firm belly doesn’t always mean digestive trouble. And even milk production can happen purely from hormones, even without mating.

Luci’s appetite stayed inconsistent for a while after her cycle, which I now know is normal for some dogs. And the biggest lesson of all: when something feels off, calling the vet is always the right move.

These girls keep me on my toes, but they also make me a better, more observant dog mom every single day.
