Thank you HW for that information, more information than 2 different vets have given us. Bad breeding practice was the phrase used by the vet who conducted the ultrasound and told us to get our vet practice to write a letter to the breeder to stop further this practice, stating the breeder must have known (which has heightened our anger and upset). This is our first dog so we are very new to this. You are a better googler than us as we did not come across that article on our searches. Thanks again, we are very appreciative.
