Proestrus: A dog’s oestrogen levels start to rise in preparation for her to release her ova (eggs). Her vulva may swell and she may produce a bloody discharge. Although male dogs may begin to take an interest in her, she may not be keen to mate, and may not be happy about dogs sniffing around her. This stage usually lasts for around nine days, but varies from dog to dog. Similarly, certain medications can cause dogs to pant excessively because they mimic Cushing’s Syndrome.
