Oral thrush is a fungal infection of the mouth. It is not contagious and is usually successfully treated with antifungal medication. It is also called oral candidosis (or candiasis) because it is caused by a group of yeasts called Candida. Symptoms of oral thrush can include: 1  white patches (plaques) in the mouth that can often be wiped off, leaving behind red areas that may bleed slightly. 2  loss of taste or an unpleasant taste in the mouth. 3  redness inside the mouth and throat.
The estrus cycle has four stages. The first stage is called proestrus. This lasts approximately 10 days and it is during this stage that your dog will bleed from the vaginal area. This is your dog's preparation for pregnancy phase, but she will not want to mate with a male during this time.
The first heat cycle typically takes place between six and nine months old, but breeds that mature more slowly may not experience a first heat until twelve to eighteen months of age. Cycle Length A normal heat cycle lasts approximately three weeks. In the beginning stages, known as proestrus, a bitch's vulva begins to swell, and you may notice her licking herself more than usual. Male dogs will also begin sniffing her more as her hormones begin to produce a scent that signals she is becoming ready to breed. Stages of Heat
