Hypersensitivity Skin Disorders

Clinical hypersensitivity disorders have been classified by Gel and Coombes. The following description is simplified since in many instances complex interactions occur simultaneously. Type 1 (immediate, anaphylactic) genetically susceptible individuals inhale (absorb percutaneously?) allergens such as pollen and house dust, and produce immunoglobulin E (IgE), which fixes to tissue mast cells and blood basophils the allergen subsequently comes into contact with its specific IgE, leading to the release of vasoactive amines, which cause tissue damage examples are urticaria, angio-oedema, atopy, drug eruption and flea-bite hypersensitivity Type 2 (cytotoxic) IgG or IgM with or without complement binds to complete antigens on body tissues the antigen—antibody reaction causes cell lysis examples are pemphigus, pemphigoid, cold agglutinin disease and dnig eruption Type 3 (immune complex) circulating antigen-antibody complexes fix complement and are deposited in blood vessel walls these complexes attract neutrophils; proteolytic and hydrolytic enzymes released from the neutrophils produce tissue damage examples are systemic lupus erythematosus and bacterial hypersensitivity Type 4 (delayed) incomplete Read more […]

The Trachea and Major Bronchi

Cough is the most common clinical sign associated with tracheal and bronchial disease. Following a history and thorough physical examination to rule out infectious tracheobronchitis, thoracic and soft-tissue cervical radiographs may be indicated. Thoracic radiography is perhaps the single most important diagnostic test in the evaluation of the puppy or kitten that presents with cough as its primary complaint. Tracheal hypoplasia, extraluminal compressive diseases, diseases causing tracheal stenosis, intraluminal masses, and tracheal collapse may be apparent radiographically. Tracheoscopy with a small-diameter endoscope (approximately 3.5 to 5 mm in diameter or a rigid arthroscope) is useful in evaluating the trachea when obstructive or mucosal disease is suspected. It is especially useful in the diagnosis of tracheal collapse, tracheal foreign body, tracheal stenosis, parasitic tracheobronchitis, and tracheal osteochondroma. Congenital Disorders PRIMARY CILIARY DYSKINESIA Primary ciliary dyskinesia is a congenital respiratory disorder that is characterized by absent or deficient mucociliary clearance (). The ciliary dysfunction reduces mucociliary transport, which frequently leads to persistent or recurrent rhinitis, Read more […]

Basic Training: Command HEEL

In the wild a dog can roam free and exercise himself. In the city you have to make sure he gets enough exercise by walking him and Playing with him. Professional dog walkers are fine, but if you walk your dog yourself, the experience will be far more rewarding. A six-foot leash is fine and its purpose is not only to keep your dog from running away, but also to teach him that he is to stay by your side. Every client is taught how to walk his dog properly. The dog should walk and not pull you down the street. Ideally, your dog should now know enough to sit and stay when he’s told to. But what’s to keep him at your side when you’re actually walking him? If you can’t answer that one, you are in for some unpleasant experiences. One woman’s two great Danes pulled her down the street three times a day until the dogs saw a cat on the other side of the street. A strikingly beautiful girl, who never owned even one dog bought two English setters to promenade in the park. One day both dogs headed for the same telephone pole, and each dog opted for a different side… Heeling is as important for your dog as it is for you. Which of us hasn’t seen a small dog straining against his leash at a 45-degree angle, choking and gagging Read more […]

Genetics and the Dog: Breed Action

In some breeds, admitting to the occurrence of an inherited defect is hazardous. Many breeders will openly condemn those who confess to having had a problem. It is as if breeders believe that silence will make the defect go away. This is clearly not the case, indeed, it is more likely that defects will spread. It is far more mature to admit to problems and collectively try to solve them. In the short term there may be heartache and economic loss for some, but in the long term the breed will benefit. It is crucial that breeders do not simply rely on pedigree data vvhen trying to evaluate problems. If a defect is recessive or suspected as being recessive, then the need is not only for five generation pedigrees of affected animals but also numbers of the litter born, their sexes status and, in the case of defects seen in later life, the age at examination. Given such data, a geneticist can help a breed examine the problem in depth. Given a list of “affected” pedigrees only on is in danger of “tracing the defect to a certain dog” without being aware that all pedigrees, affected and normal, trace to him. Any widely used stud might appear in “affected” pedigree without actually being the source of the problem though in some Read more […]

Canine Terminology – B

BACK The anatomical division of the spine is neck, withers, back, loin and croup, each variable in meaning depending upon the context of the Standard. In a few dog Standards, the five vertebrae between the withers and loin. BELTON A coat colour, especially of English Setters. A coat with ticking or flecking in the base colour (white): blue belton (dilute black or black ticking);orange Belton; liver Belton; or lemon Belton . Ticking is a genetic pattern that may carry any pigment as black, tan (brown) or yellow. BITCHY Effeminate male (derogatory) or typically feminine female. BITE Determined when the mouth is closed. The position of the upper and lower teeth relative to one another. Level bite is where the upper and lower teeth meet exactly. In a scissors bite the upper teeth extend beyond the lower teeth, but surfaces touch one another. See also overshot and undershot. BLAZE A white stripe or line extending up the centre of the face.
