How to tell if a Dachshund is in heat? The external observation method is to determine whether the bitch is in heat by observing her behavioral performance and vaginal discharge; the vaginal examination method is to analyze the cell tissue of the vaginal smear to determine whether the bitch is in heat or not. The method of development; the test method is to use a male dog to test.

External observation method

Usually female dogs will show certain symptoms a few weeks before the onset of estrus, usually changes in appetite and appearance. Some females naturally abhor the company of other female dogs when there are male dogs nearby. A few days before the symptoms of proestrus appear, most female dogs become listless and indifferent. The characteristics of the early stage of hair loss are: swelling of the external reproductive organs, and blood-like discharge from the vulva that lasts for several days. When the blood outflow increases, the vulva and vestibule become larger and feel swollen when touched; the female dog's temperament becomes restless and excited, It does not respond to commands that can be obeyed at other times; it drinks more water and urinates frequently, which can significantly attract male dogs; if not controlled, it will travel and lure male dogs, but refuse to mate. Counting from proestrus, most female dogs accept male dogs for mating (enter estrus) within 6 days. At this time, the blood discharge is greatly reduced, and they stand waiting for mating. Inexperienced bitches will often perform several mating positions between short bursts of teasing before being allowed to mate. After the estrus period, the external reproductive organs become soft and deflated, a small amount of dark brown discharge can be seen, and the female dog becomes more and more peaceful.

Vaginal examination

In proestrus, the dog vaginal smear contains a lot of keratinized epithelial cells with pyknotic nuclei, a lot of red blood cells, a small amount of white blood cells and a lot of debris. During estrus, the smear contains many keratinized epithelial cells and red blood cells, but no white blood cells. After ovulation, leukocytes occupy the vaginal wall, along with the appearance of degenerated epithelial cells. In late estrus, the smear contains many white blood cells, non-keratinized epithelial cells and a small amount of keratinized epithelial cells. In the smear during estrus, the epithelial cells are non-keratinized, but before the next proestrus, the epithelial cells become keratinized. change.

Testing method

If the female dog allows mating, it means that the female dog has entered estrus. Testing for male love can be done with castrated male dogs or normal male dogs.
