Hormones can affect the body, and it is possible this is a result of the hormones from being in heat. Another cause can be pseudopregnancy, where the body thinks it is pregnant even if it is not. Dogs may gain weight, produce milk or show other behaviors similar to pregnancy. It is best to bring Chanel into the vet for a complete exam to rule this and any other health conditions out.

    It is quite possible she could be pregnant, or may be suffering a false pregnancy. An ultrasound exam by your vet is recommended to see what is going on so you can start and prepare for puppies if they are on the way - you will need to arrange to segregate the male from the nursing mother if you are going ahead with the pups
