However, I can tell you that early signs of pregnancy in dogs can be subtle and may mimic other conditions. Some common symptoms include:
* Changes in appetite: Increased appetite early on, followed by a decrease later in pregnancy.
* Nipple enlargement and darkening: This is a prominent sign, especially starting around 3 weeks.
* Changes in behavior: Some dogs become more affectionate, while others become more withdrawn.
* Vomiting and/or lethargy: These can be common in the early stages.
It's crucial to remember that these symptoms can also be caused by other factors. A vet can confirm pregnancy through a physical exam, ultrasound, or blood test.
If you suspect your dog might be pregnant, schedule an appointment with your veterinarian immediately. They will be able to provide the best advice for your dog's care and well-being throughout the pregnancy.
