You can tell how far along a pregnant dog is through veterinary methods like ultrasound (around 28 days to count puppies) or X-rays (late pregnancy for accurate count) and by observing physical signs like nipple changes (around 3-4 weeks) and a growing belly, though a vet is crucial for confirmation and timing, generally using a dog's ~63-day gestation period as a guide.
Dog pregnancy diagnosis. Your vet can confirm a pregnancy with either a dog pregnancy test, which measures her hormone levels, from days 21-25 of her term, or by ultrasound from day 20-22. From around day 30 your vet will be able to carry out a physical examination to count how many puppies your dog is having.
Signs that she is nearing labor (typically within a week) include panting, increased nesting or digging behavior, appearing 'needy,' or having very frequent urination. However, these signs may not always be present or can appear well in advance, so monitoring her rectal temperature is a more reliable method.
Feeling puppies move inside a pregnant dog typically occurs around 4--6 weeks into gestation. Movements are subtle at first, becoming more noticeable as fetuses grow. Symptoms include gentle kicks or shifts in the abdomen. Monitoring fetal activity helps assess pregnancy health.
Weeks 5-6: The fetus is starting to look more like a puppy! Tiny toes, nails and whiskers have formed. The fetus's organs have completely developed, along with its skin color. At the six-week mark, the fetus has sex organs and begins to develop into either a male or a female.
Week 5-6 of Dog Pregnancy
The puppies will begin gaining weight at this time and will become fetuses, rather than embryos. During these two weeks, puppies will increase in weight by about 75%, and your dog will begin to quickly show outward signs of being pregnant, too.
This fetal death can occur at any time during pregnancy, though the signs of miscarriage vary depending on the stage at which it occurs.
Yes! In the late stage of pregnancy (weeks 7-9), you should be able to feel or even see the puppies moving around in your dog's tummy. Be sure to touch your dog's belly gently and carefully, and stop if she seems uncertain.
The 777 Puppy Rule (or Rule of 7s) is a guideline for puppy socialization, suggesting that by seven weeks old, a puppy should experience seven different Surfaces, seven different Sounds, seven different Objects, seven different People, seven different Locations, seven different Containers, and seven different Challenges, all in positive, short, and safe ways to build confidence and resilience. It helps prevent fear and reactivity by creating positive associations with novel experiences during the critical socialization window (around 4-16 weeks).
Most canines show signs of pregnancy in the second or third week. Their midsections will seem firmer and more rounded. You can check your dog's belly to see any puppies there. The puppies will be simpler to feel as the pregnancy goes on.
Stage 1: The Early Contractions
The first stage of labor is marked by contractions that may be invisible from the outside. Your dog might seem anxious or restless as her body prepares to give birth. This stage can last anywhere from 6 to 12 hours.
An average litter can be anywhere from one to 12 puppies, with the average litter size being around four to six puppies.
Early signs of labour are typically felt between 37 and 42 weeks of pregnancy. Early signs of labour include cramps, a 'show' or your waters breaking. A 'show' is bloodstained vaginal discharge. Braxton Hicks contractions are not true labour contractions.
At 7 weeks in, we were able to put our hands gently on her belly while she lay on her back (Tollers love to lay on their back!). We could feel gentle kicks and the movement of the pups. Their skeletons begin to solidify at this stage, and by week 8 they are solid enough to be visible on x-ray.
“Many people report that their dogs are more affectionate and/or protective during their pregnancies,” says Barrack. “Presumably, these behavioral changes are due to changes in a pregnant owner's mood coupled with hormonal and scent changes.”
The 3-second rule for puppies (and dogs) is a guideline for positive greetings and interactions, suggesting initial meetings or petting sessions last no more than three seconds before pausing, allowing the dog to choose to re-engage, which helps build confidence, reduce overstimulation, and prevent negative reactions like fear or aggression. It teaches dogs that social contact is on their terms, using short, controlled sniff-and-greet intervals (3 seconds), then disengaging, and repeating as needed, while also being used for petting to let dogs signal they want more.
Puppy difficulty at ages 2-3 months
A smaller percentage of owners voted 8-12 weeks as the toughest age. The common difficulties at this age are mainly related to potty-training and not sleeping through the night.
Red flag puppy behaviors signal serious issues beyond normal puppy antics, including aggression (growling, snapping, biting, lunging), extreme fear/anxiety (intense cowering, hiding, refusing treats, constant escape attempts, shutting down), resource guarding (guarding food/toys with aggression), and severe separation anxiety (destructive behavior when alone). Recognizing these early and seeking professional help from a trainer or vet is crucial, as these often stem from trauma or lack of socialization and won't just disappear with age.
Avoid any rigorous activity, or even training/obedience schooling during your dog's pregnancy; this can be stressful, and bumps or knocks from other dogs could hurt her unborn pups.
Will handling newborn puppies cause the mother to reject them? It is a myth that human scent will cause a mother to reject her puppies. However, excessive handling can stress the mother and puppies, which is why minimal handling is recommended initially.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, representing 3 days (overwhelmed/hiding), 3 weeks (settling in/testing boundaries), and 3 months (feeling at home/bonding) to help owners manage expectations and provide patience, routine, and a calm environment, understanding that anxiety is normal as they decompress from a stressful past. It's a framework for recognizing stress and fostering trust, not a rigid timeline, but it helps owners understand why a new dog might seem timid or act out initially.
Enlarged or Discolored Nipples
The areolas also become somewhat rounded compared to their usual flatness. You may also notice your dog's nipples turning a slightly darker red than normal, which would indicate an increase in blood flow. Later into the pregnancy, her nipples may occasionally leak milk, as well.
If a puppy dies inside the mother and is not delivered or resorbed, it can lead to infection or sepsis, putting the mother's life at risk. Professional veterinary care is needed to manage the situation safely.
Most miscarriages happen in the first trimester, especially between weeks 6 and 8, with the risk decreasing significantly as the pregnancy progresses, particularly after a heartbeat is detected. About 80% of losses occur before 12 weeks, and the rate drops sharply after week 12, with a very low risk after 16 weeks.
