No. Only a male can impregnate a female. No female mammal of any species can get another female pregnant. For mammals that have a "heat" cycle, being in "heat" is required for pregnancy by a male. If such a mammal (a dog for instance) is not in heat or doesn't have a male partner, pregnancy is not possible.
A donkey's heat cycle can vary since no two donkeys are the same. However, the average heat cycle tends to be anywhere between 23 and 30 days.
Female rabbits don't go into heat. Ovulation in rabbits is triggered by fornication, so they don't have a menstrual cycle.
my female jack russel has not been on heat since november, why is this/
The answer is yes, but for only part of the heat cycle will a female is receptive to breeding. On average, this phase (called the estrus phase) begins around day 9 or 10 from the initial onset of the cycle. It is only at this point in the cycle when a female will allow and even encourage mating.
A female dog's heat cycle or estrus typically lasts around 2-4 weeks. This cycle is divided into four stages: proestrus, estrus, diestrus, and anestrus. During the estrus stage, which is when she is fertile, the female dog may actively seek out males for breeding.
Female mules typically do not have a regular heat cycle like mares. They are usually infertile due to the mismatched number of chromosomes from their horse and donkey parents.
Female dogs go through a heat cycle, called estrus, every six months. She will have proestrus, or a bleeding cycle, before her true heat cycle during which she is very receptive to the advances of male dogs. This heat cycle lasts for several days up to three or four weeks. Some female dogs will undergo personality changes during this time, the most common changes being anxiety and irritability.
