When my daughter was pregnant our dog quite often lay across her tummy, in an almost protective way. Sadly there was something wrong with the baby & she never lived. The dog did not appear to be so protective of her 2nd pregnancy & the baby was born perfectly healthy. It might just be a coincidence, but you read about dogs appearing to have a 6th sense.
Interested in other dog owners appsrent 6tb sense moments with their dogs....
