Anal glands: Glands which secrete a pungent substance that is used by a dog to mark its territory. Located on each side of the anus. Periodic expressing may be needed on many dogs

Angulation: Angles created by bones meeting at their given joints. Photo shows rear angulation examples.

Artificial Insemination: The introduction of semen into the female reproductive tract by artificial means. Usually one of three ways, directly by surgery into the uterus, (TCI) Trans-cervical in which a rigid endoscope is used to locate the cervix and pass a catheter through it for intrauterine insemination about 20 inches, or a simple (AI) by collecting the dog and by a narrow tube releasing concentrated semen about 12 inches up into the female rottweiler.

It is also commonly referred to as torsion and gastric torsion when the stomach is also twisted. The word bloat is often used as a general term to cover gas distension of the stomach with or without twisting. In dogs, gas accumulation in the stomach is usually associated with volvulus of the stomach, which prevents gas from escaping. Deep-chested breeds are especially at risk. Mortality rates in dogs range from 10 to 60 percent, even with treatment. With surgery, the mortality rate is 15 to 33 percent. Most common in deep-chested dogs and can rapidly lead to death if untreated.

Canine Good CitizenĀ® (CGC): (CGC) program, established in 1989, is an American Kennel Club program to promote responsible dog ownership and to encourage the training of well-mannered dogs. A dog and handler team must take a short behavioral evaluation of less than half an hour; dogs who pass the evaluation earn the Canine Good Citizen certificate, which many people represent after the dog's name, abbreviating it as CGC; for example, "Fido, CGC". The evaluation consists of ten objectives. All items must be completed satisfactorily or the team fails. Test items include:

CH: A title conferred on a dog by the AKC as a result of defeating a specified number of dogs in specified competition at a series of AKC-licensed or -member dog shows.

Champion: A title conferred on a dog by the AKC as a result of defeating a specified number of dogs in specified competition at a series of AKC-licensed or -member dog shows.

Close-Coupled: Comparatively short from the last rib to the commencement of the hindquarters; occasionally used to characterize a comparative shortness from withers to hipbones.

Colostrum: Newborns have very immature digestive systems, and colostrum delivers its nutrients in a very concentrated low-volume form. It has a mild laxative effect, encouraging the passing of the baby's first stool, which is called meconium. Colostrum is known to contain immune cells (as lymphocytes) and many antibodies Colostrum is crucial for newborn farm animals. They receive no passive transfer of immunity via the placenta before birth, so any antibodies that they need have to be ingested. This oral transfer of immunity can occur because the newborn's stomach is porous. This means that large proteins (such as antibodies) can pass through the stomach wall. The newborn animal must receive colostrum within 6 hours of being born for maximal transfer of antibodies to occur. The stomach wall remains somewhat open up to 24 hours of age, but transfer is more limited.

It is then processed and the dogs record proves his unique DNA profile. Results must be processed by an AKC-approved facility to be accepted by AKC.

Dock: is the removal of a portion of an animal's tail. Tail docking occurs in one of two ways. The first involves constricting the blood supply to the tail with a rubber ligature for a couple days until the tail falls off.

Eclampsia occurs most commonly when the puppies are one to five weeks of age and the mother is producing the most milk. Eclampsia is not due to an overall lack of calcium; it merely indicates that the nursing female cannot mobilize sufficient supplies of stored calcium quickly enough to meet her metabolic needs. Females that are particularly good mothers, especially attentive to their puppies, seem to be more likely to develop eclampsia. Signs of eclampsia include tremors, weakness and a form of paralysis called puerperal tetany characterized by stiff limbs and an inability to stand or walk. Eclampsia is considered an immediate emergency and medical attention should be sought.
