Whelping Box
A whelping box/den, also known as a nesting box, whelping den or whelping pen, is designed to protect puppies during birth (whelping) and early life by keeping them safely contained, protected from cold, and safe from the danger of crushing or smothering by the mother. Whelping boxes vary from improvised cardboard boxes, durable corrugated plastic to purpose built equipment, typically made of plywood or plastic. Desirable features include ease of cleaning and sanitation, extendibility, and toughness. However, there can sometimes not be enough traction, and with the added factor of an unnaturally flat floor, often puppies can develop, and suffer from what is known as hip dysplasia. Also whelping dens exist, which are whelping boxes that are enclosed on top. Commercially available whelping boxes often feature accommodations for accessories such as heat control devices and IP camera attachment. The sides of the box are designed to be high enough to safely contain the puppies, yet lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whelping Box With Extension
Birth is the act or process of bearing or bringing forth offspring, also referred to in technical contexts as parturition. In mammals, the process is initiated by hormones which cause the muscular walls of the uterus to contract, expelling the fetus at a developmental stage when it is ready to feed and breathe. In some species, the offspring is precocial and can move around almost immediately after birth but in others, it is altricial and completely dependent on parenting. In marsupials, the fetus is born at a very immature stage after a short gestation and develops further in its mother's womb Pouch (marsupial), pouch. It is not only mammals that give birth. Some reptiles, amphibians, fish and invertebrates carry their developing young inside them. Some of these are Ovoviviparity, ovoviviparous, with the eggs being hatched inside the mother's body, and others are Viviparity, viviparous, with the embryo developing inside their body, as in the case of mammals.

Puppy
A puppy is a Juvenile (organism), juvenile dog, generally one less than 12-18 months old. Puppies are markedly underdeveloped and dependent on their mothers at birth (displaying ''altriciality''), but healthy puppies grow quickly and begin walking thereafter. Puppies generally weigh shortly after birth, depending on the breed. A puppy's coat colour may change as the puppy grows older, as is commonly seen in breeds such as the Yorkshire Terrier. ''Puppy'' refers specifically to young dogs, while ''pup'' may be used for other animals such as wolf, wolves, Pinniped, seals, giraffes, guinea pigs, rats, or sharks. Prenatal development Dogs go through prenatal development before they are born, just like all animals do. The germinal stage, the embryonic stage, and the fetal stage are the three phases that make up this development. The first stage of prenatal growth in dogs is known as the germinal stage, which starts at fertilization and lasts for about two weeks. The ferti ...

IP Camera
An Internet Protocol camera, or IP camera, is a type of digital video camera that receives control data and sends image data via an IP network. They are commonly used for surveillance, but, unlike analog closed-circuit television (CCTV) cameras, they require no local recording device, only a local area network. Most IP cameras are webcams, but the term ''IP camera'' or netcam usually applies only to those that can be directly accessed over a network connection. Some IP cameras require support of a central network video recorder (NVR) to handle the recording, video and alarm management. Others are able to operate in a decentralized manner with no NVR needed, as the camera is able to record directly to any local or remote storage media. The first IP Camera was invented by Axis Communications in 1996. History The first centralized IP camera, the ''AXIS Neteye 200'', was released in 1996 by Axis Communications. Although the product was advertised to be accessible from any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammary Glands
A mammary gland is an exocrine gland that produces milk in humans and other mammals. Mammals get their name from the Latin word ''mamma'', "breast". The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the dugs of other animals (for example, dogs and cats) to feed young offspring. Lactorrhea, the occasional production of milk by the glands, can occur in any mammal, but in most mammals, lactation, the production of enough milk for nursing, occurs only in phenotypic females who have gestated in recent months or years. It is directed by hormonal guidance from sex steroids. In a few mammalian species, male lactation can occur. With humans, male lactation can occur only under specific circumstances. Mammals are divided into 3 groups: monotremes, metatherians, and eutherians. In the case of monotremes, their mammary glands are modified sebaceou ...

Dog Breeding
Dog breeding is the practice of mating selected dogs with the intention of maintaining or producing specific qualities and characteristics. When dogs reproduce without such human intervention, their offspring's characteristics are determined by natural selection, while "dog breeding" refers specifically to the artificial selection of dogs, in which dogs are intentionally bred by their owners. Breeding relies on the science of genetics, hence a breeder who is knowledgeable on canine genetics, health, and the intended purpose of the dogs attempts to breed suitable dogs. Terminology The female parent of puppies is referred to as the ''dam'' and the male parent is referred to as the ''sire''. A litter consists of the puppies born from the same pregnancy. A ''whelp'' is a newborn puppy and giving birth to dogs is called ''whelping''. Dogs commonly give birth in a '' whelping box'', a simple box or pen provided to the dam to help shelter and contain the puppies. A person who intent ...
