http://en.wikipedia.org/wiki/Canine_herpesvirus
Canine herpesvirus (CHV) is a virus of the family Herpesviridae which most importantly causes a fatal hemorrhagic disease in puppies (and in wild Canidae) less than two to three weeks old. It is known to exist in the United States, Canada, Australia, Japan, England and Germany.[1] CHV was first recognized in the mid 1960s from a fatal disease in puppies.[2]
CHV in puppies
The incubation period of CHV is six to ten days.[3] CHV is transmitted to puppies in the birth canal and by contact with infected oral and nasal secretions from the mother or other infected dogs, but it is not spread through the air.[1] The virus replicates in the surface cells of the nasal mucosa, tonsils, and pharynx. Low body temperature allows the virus to spread and infect the rest of the body.[4] Symptoms include crying, weakness, depression, discharge from the nose, soft, yellow feces, and a loss of the sucking reflex. CHV also causes a necrotizing vasculitis that results in hemorrhage around the blood vessels.[5] Bruising of the belly may occur. Eye lesions include keratitis, uveitis, optic neuritis, retinitis, and retinal dysplasia.[6] There is a high mortality rate, approaching 80 percent in puppies less than one week old,[7] and death usually occurs in one to two days.[8]
In puppies three to five weeks old, the disease is less severe due to their ability to properly maintain body temperature and mount a febrile response.[7] More puppies survive, but they can develop a latent infection. Some later get neurologic disease and have symptoms like difficulty walking and blindness. Reactivation of a latent infection may be caused by stress or immunosuppressive drugs such as corticosteroids.[6] The site of latency has been shown to be the trigeminal ganglion and possibly the lumbosacral ganglion.[9]
CHV in adult dogs
In adult dogs, the virus infects the reproductive tract, which allows it to be sexually transmitted or passed to puppies during birth. The disease can cause abortion, stillbirths, and infertility. It is also an infrequent cause of kennel cough.
Like other types of herpesvirus, previously infected dogs can from time to time release the virus in vaginal secretions, penile secretions, and discharge from the nose. Raised sores in the vagina or on the penis may be seen during these times. Spread of the disease is controlled by not breeding dogs known to have it. Serology can show what dogs have been exposed (although not all of them will be releasing the virus at that time). Serological studies of various dog populations have revealed a seroprevalence of 40 to 93 percent.[6] Bitches who have a negative serology for CHV should be isolated from other dogs from three weeks before to three weeks after giving birth.[8] Bitches that have lost puppies to the disease may have future litters that survive due to transfer of antibodies in the milk.

I appreciate the fact that you are trying to post intelligent things, but most of the random "diseases" you are posting about are in the vax that puppies receive from 8 weeks on. Perhaps you would do better to post on Erlichiosis, another tick disease that is becoming very prevelant in dogs due to interstate travel. We saw it several times in retired Greyhounds from the tracks, by traveling they were spreading it from state to state. It is a very aggressive disease and can quickly turn fatal. Most vets use the Snap 4DX test for a dogs yearly Heartworm test, these other tick diseases are included in this test. Might I suggest a thread on Leptosporosis, as this is becoming increasingly more prevelant, especially with alot of breeders no longer vax for it due to the possible side affects. Or Canine Influenza?
