Cody’s definitely pregnant. Viewed from above, her sides form a staight line from shoulder to hip instead of curving inwards at the hips. Also, I detected a pink teat peeking out from her white fur. A breeder once told me that his labrador bitch didn’t show until the week before she was due.
Her veterinarian will do x-rays next week, one week before she’s due to see how many pups she’ll have and the size of the pups.
Cody is a petite girl, this is her first litter, so monitoring is very important.
