Puppy (musician)
A puppy is a Juvenile (organism), juvenile dog. Some puppies can weigh , while larger ones can weigh up to . All puppies display primary altriciality and healthy puppies grow quickly after birth. A puppy's coat color 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 fertilized egg, also known as the zygote, travels through the fallopian tube to the uterus during this period while undergoing rapid cell divisio ...

Lactation
Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young. The process naturally occurs with all sexually mature female mammals, although it may predate mammals. The process of feeding milk in all animals (including humans) is called ''nursing'', and in humans it is also called ''breastfeeding''. Newborn infants often produce some milk from their own breast tissue, known colloquially as witch's milk. In most species, lactation is a sign that the female has been pregnant at some point in her life, although it can happen without pregnancy. Nearly every species of mammal has nipples; except for monotremes, egg-laying mammals, which instead release milk through ducts in the abdomen. In only one species of mammal, the Dayak fruit bat from Southeast Asia, is milk production a normal male function. ''Galactopoiesis'' is the maintenance of milk production. This stage requires prolactin. Oxytocin is critical for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veterinarian
A veterinarian (vet), also known as a veterinary surgeon or veterinary physician, is a medical professional who practices veterinary medicine. They manage a wide range of health conditions and injuries in non-human animals. Along with this, vets also play a role in animal reproduction, animal health management, conservation, husbandry and breeding and preventive medicine like animal nutrition, vaccination and parasitic control as well as biosecurity and zoonotic disease surveillance and prevention. Description In many countries, the local nomenclature for a veterinarian is a regulated and protected term, meaning that members of the public without the prerequisite qualifications and/or licensure are not able to use the title. This title is selective in order to produce the most knowledgeable veterinarians that pass these qualifications. In many cases, the activities that may be undertaken by a veterinarian (such as treatment of illness or surgery in animals) are restricted only t ...

Dewclaw
A dewclaw is a digit – vestigial in some animals – on the foot of many mammals, birds, and reptiles (including some extinct orders, like certain theropods). It commonly grows higher on the leg than the rest of the foot, such that in digitigrade or unguligrade species it does not make contact with the ground when the animal is standing. The name refers to the dewclaw's alleged tendency to brush dew away from the grass.Danziger, D., & McCrum, M. (2008). ''The Thingummy: A book about those everyday objects you just can't name''. London: Doubleday. On dogs and cats the dewclaws are on the inside of the front legs, similarly to a human's thumb, which shares evolutionary homology. Although many animals have dewclaws, other similar species do not, such as horses, giraffes and the African wild dog. Dogs Dogs almost always have dewclaws on the inside of the front legs and occasionally also on the hind legs. Unlike front dewclaws, rear dewclaws tend to have little bone or muscle s ...

American Veterinary Medical Association
The American Veterinary Medical Association (AVMA), founded in 1863, is a not-for-profit association representing more than 99,500 veterinarians in the US. The AVMA provides information resources, continuing education opportunities, publications, and discounts on personal and professional products, programs, and services. The AVMA indicates that it lobbies for animal friendly legislation within a framework that supports the use of animals for human purposes (e.g., food, fiber, research, companionship). The AVMA Council on Education is the designated accrediting body for schools of veterinary medicine in the United States. The AVMA publishes the ''Journal of the American Veterinary Medical Association'' (JAVMA) and the ''American Journal of Veterinary Research'' (AJVR). The AVMA's veterinary student organization is the Student American Veterinary Medical Association (SAVMA). History The American Veterinary Medical Association (AVMA) was founded in 1863, when 40 delegates rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Docking (dog)
Docking is the removal of portions of an animal's tail. While docking and bobbing are more commonly used to refer to removal of the tail, the term cropping is used in reference to the ears. Tail docking occurs in one of two ways. The first involves constricting the blood supply to the tail with a rubber ligature for a few days until the tail falls off. The second involves the severance of the tail with surgical scissors or a scalpel. The length to which tails are docked varies by breed, and is often specified in the breed standard. Docking is illegal, or restricted, in many countries. Some dog breeds have naturally occurring bobtail lines. These appear similar to docked dogs but are a distinct naturally occurring phenotype. History Purpose Historically, tail docking was thought to prevent rabies, strengthen the back, increase the animal's speed, and prevent injuries when ratting, fighting, and baiting. Tail docking is done in modern times either for prophylactic, therapeu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Kennel Club
The American Kennel Club (AKC) is a registry of purebred dog pedigrees in the United States. In addition to maintaining its pedigree registry, this kennel club also promotes and sanctions events for purebred dogs, including the Westminster Kennel Club Dog Show, an annual event which predates the official forming of the AKC, the National Dog Show and the AKC National Championship. The AKC is a non-member partner with the Fédération Cynologique Internationale. The AKC recognizes 200 dog breeds, as of 2022. History In the early 1800s, the English became concerned with the beauty of dogs as well as their function. This fad spread to North America, and in 1877, the Westminster Kennel Club Dog Show began. Soon after, the need for a regulating body became obvious. The National American Kennel Club, which had been founded in 1876, began to publish and make publicly available its studbook in 1879. This organization, however, had a more vested interest in field trials than in conformat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sparring
Sparring is a form of training common to many combat sports. Although the precise form varies, it is essentially relatively ' free-form' fighting, with enough rules, customs, or agreements to minimize injuries. By extension, argumentative debate is sometimes called sparring. Differences between styles The physical nature of sparring naturally varies with the nature of the skills it is intended to develop; sparring in a striking art such as Chun Kuk Do will normally begin with the players at opposite sides of the ring and will be given a point for striking the appropriate area and will be given a foul for striking an inappropriate area or stepping out of the ring. Sparring in a grappling art such as judo might begin with the partners holding one another and end if they separate. The organization of sparring matches also varies; if the participants know each other well and are friendly, it may be sufficient for them to simply play, without rules, referee, or timer. If the sparring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retinas
The retina (from la, rete "net") is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. The retina serves a function which is in many ways analogous to that of the film or image sensor in a camera. The neural retina consists of several layers of neurons interconnected by synapses and is supported by an outer layer of pigmented epithelial cells. The primary light-sensing cells in the retina are the photoreceptor cells, which are of two types: rods and cones. Rods function mainly in dim light and provide monochromatic vision. Cones function in well-lit conditions and are responsible for the perception of colour through the use of a range of opsins, as well as high-acuity vision used for tasks s ...

Birth
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. It is not only mammals that give birth. Some reptiles, amphibians, fish and invertebrates carry their developing young inside them. Some of these are ovoviviparous, with the eggs being hatched inside the mother's body, and others are viviparous, with the embryo developing inside her body, as in the case of mammals. Mammals Large mammals, such as primates, cattle, horses, some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
