Do female dog's know yes , do male dogs yes ,do they know if a human female is pregnant yes. They hear the fetus in the womb They smell the difference in the human odor. they know!
Licking is very common when the female is pregnant. But it is important to try and limit this kind of contact (or any contact with other dogs) about three weeks prior to and three weeks after the birth to protect the puppies from catching anything from the other adults. A minor illness can be fatal to the puppies if contracted during thatperiods
With pregnancy and pseudopregnancies they still act as though they are pregnant; they start nesting, temperature drops, act restless and even start lactating, etc.. To know for sure take your dog to the vet. They can tell if she's pregnant via ultrasound 28 days into her pregnancy or radiography 45 days. Get her spayed! There's enough dogs in a pound who need a loving home! The world doesnt need anymore dogs:(
Okay smartass, well when conception happens the dog goes into protestrus meaning they can't sense that the dog is in heat anymore. Fix your animal.
I can only say that our female dog's behaviour changed when I was pregnant. She'd sit close and between me and visitors. She was actually my mother inlaws dog who lived with us so it was a noticeable change.
I don't think so... when my girl had puppies, she just got rounder (MUCH rounder, lol). The guys didn't notice until the puppies came around :)
