Canine Parturition/Whelping. The best way to know when the dog is going to whelp is to have ovulation timing and specific hormone and breeding dates. Often we do not have that information, and since the average gestation is 63 days but can be between 57 to 72 days from a single breeding, it can be difficult to tell when the dog is going to whelp. Canine parturition/whelping occurs in 3 stages. The first stage is when the uterus begins to contract and cause the cervix to dilate. Stage one can last 6 to 12 hours in the dog. Signs that you may see in the female are restlessness, panting, pacing, or nesting type behavior.
The animal does not appear ill during this time. The time between the bite and the appearance of symptoms is called the incubation period and it may last for weeks to months. A bite by the animal during the incubation period does not carry a risk of rabies because the virus has not yet made it to the saliva.xtensive studies on dogs, cats, and ferrets show that the rabies virus can be excreted in the saliva of infected animals several days before illness is apparent.
