Part 1 of 3: Your Dog Isn’t Acting Strange — She’s in Heat (Here’s What’s Really Happening)

One day your dog is her normal self…

The next?

She’s pacing.
Clingy.
Distracted.
Maybe even a little emotional.

It can feel like her personality changed overnight.

But it didn’t.

Her hormones did.

At Myco Pet, we believe when you understand what’s happening inside your dog’s body, everything on the outside starts to make sense.

🔬 The Heat Cycle — A Full-Body Shift

The heat cycle isn’t just about reproduction.

It’s a whole-body hormonal process driven by:

• estrogen
• progesterone
• luteinizing hormone (LH)

These hormones influence:

• mood
• behavior
• energy
• nervous system regulation

Which is why your dog may seem like a completely different dog...I guess this is what our husbands deal with on a monthly basis hahahaha

🧠 The 4 Stages of the Heat Cycle (What You’re Actually Seeing)

Your dog moves through four distinct phases — each one feels different for her.

🌸 1. Proestrus (The Build-Up Phase)

Inside the body:

• Estrogen rises
• Blood flow increases
• The body prepares for ovulation

What you’ll see:

• swelling
• bloody discharge
• attention from male dogs
• slight restlessness

What she feels:
More alert, slightly unsettled — her system is ramping up.

💙 Support tip:
Start creating calm early. Introducing Focus & Calm here can help smooth the transition as hormones rise.

🔥 2. Estrus (The Fertile Phase)

Inside the body:

• Estrogen drops
• Progesterone rises
• Ovulation is triggered

What you’ll see:

• lighter discharge
• tail flagging
• increased affection or distraction

What she feels:
This is often the most intense phase — physically and emotionally.

💙 Support tip:
Keep stimulation low and routines consistent.
Use Focus & Calm to help her settle.

🧼 Practical note:
Discharge continues — Protect Spray helps keep bedding, floors, and surfaces clean and fresh.

🌙 3. Diestrus (The Hormonal Shift Phase)

Inside the body:

• Progesterone peaks
• The body acts as if pregnant (even if she’s not)

What you’ll see:

• lower energy
• nesting behaviors
• appetite changes

What she feels:
Sensitive, sometimes confused — her body is still in a hormonally active state.

💙 Support tip:
This is a key time for emotional support.
Focus & Calm can help stabilize mood and promote relaxation.

🌿 4. Anestrus (The Reset Phase)

Inside the body:

• Hormones return to baseline
• The system resets

What you’ll see:

• normal behavior returns
• stable energy and mood

This is her true baseline.

💙 Why She Feels “Off”

Hormones directly influence brain chemistry — especially serotonin (your dog’s “calm” signal).

When this shifts, your dog may:

• feel restless
• struggle to settle
• become more emotional

This isn’t behavior to correct.

It’s a body asking for support.
