Chaos Zlata palz always had problems with her heat, she got in heat and stopped before ovulation, they tried to give her much contact to males but even this didn´t help. They went to an endocrinology specialist and they found out she was showing hyperthyreodistic levels in her bloodcheck. Hyperthyreosis normally doesn´t exist in dogs and she was perfectly healthy, out of experience the specialist checked her diet and found out that her owners were feeding the throat part of cattles as a treat regulary. This part contains the thyreoid gland of the cattle, fed regulary it pushes the dog into an artificial Hyperthyreosis. After they changed the diet she got into regular heat, was mated without problems and got a healthy litter.
Also very often a reason for prolonged heat with no or still ovulation: not contact to males or a dominant female close by. We have to separate Amy from her mother or she stops her heat at once. Her mother isn´t dominating her at all, she is just higher in rank.
