Frequently Asked Questions
My dog has been pushing for an hour and no puppy yet – should I worry?
That's scary, I get it. A dog can push for up to 2 hours before a puppy comes. But if it's been 2 hours with steady contractions and nothing, that's an emergency. Also, if you see green discharge before any puppy, go in immediately. So if she's still straining after an hour and seems exhausted, call your vet for advice right now.
Are enlarged nipples always a sign of pregnancy?
Not always. Nipples can enlarge during heat cycles too, but in pregnancy they also darken and get more prominent. If combined with a growing belly and weight gain, it's a strong sign. But false pregnancies can mimic this exactly – that's why vet confirmation matters.
When should I start preparing the whelping box?
Around day 50–55 of pregnancy (week 7-8). That's when nesting behavior often starts. If you see your dog digging at her bed or carrying toys to a corner, set up the box then. Having it ready early lets her get used to it.
Is it expensive to confirm dog pregnancy?
An ultrasound costs $200–$500. Some vets do a pregnancy package with multiple checkups for $400–$800. Blood tests are cheaper but less accurate. If you're on a budget, you can wait for X-rays after day 45 which also show puppy count and positions.
My dog is eating less and seems tired – is that bad?
Deep breath. It's actually normal for dogs to lose appetite and get tired in the last week of pregnancy. Their body is preparing for labor. But if she also has vomiting or diarrhea, or if she's refusing water for 12+ hours, call your vet. Otherwise, just offer small meals and let her rest.
What does green discharge mean during whelping?
Green discharge means the placenta is detaching. If it happens before the first puppy arrives, that's a problem – the puppy could be stuck. If it happens after a puppy, it's normal. So if you see green before any puppy, don't wait – head to the emergency vet.
