The length of dog pregnancy varies depending on the breed and weight of the dog, but is generally about 63 days. From the beginning of pregnancy, usually around 1 month, the dog's nipples will become more prominent and the abdomen will gradually become larger. During the 5th to 6th week of pregnancy, your dog's belly will become more noticeably larger, and you may be able to spot this change by looking at your dog's belly.
In addition , dogs may also show symptoms such as fatigue and loss of appetite after pregnancy. However, determining whether the dog is pregnant and how long it has been pregnant still needs to be confirmed through veterinary examination and B-ultrasound. If you want to confirm whether your dog is pregnant, it is best to take your dog to the veterinarian for professional examination and guidance.
