DOG Ticks 1
Before and after feeding
The ARGASIDAE have 193 species are the soft ticks. This group are common in North America and feed quickly and and mainly on birds, they are very rarely found on land animals or humans.
The NUTTALLIELLIDAE consists of a single species, Nuttalliella namaqua. This is a tick found in Africa from Tanzania across to Namibia and south to South Africa. It can be distinguished from ixodid and argasid by a combination of characters including the position of the stigmata, heavily corrugated integument, and form of the fenestrated plates.
These bloodsuckers which are not insects but arachnids, attach themselves to cats, dogs and even humans. Ticks will feed on any and virtually all parts of the body, some feed on the head, shoulders and neck, with others preferring the ears, tail and toes. When they congregate in tightly packed clumps, it is almost impossible to recognise the tick as an individual parasite as they cover visible skin and fur and resemble jelly-
The effects which such bloodsucking ticks have upon their victims can be understood clearly just by seeing the difference in the size of these parasites before and after feasting! If you imaging 10 of more of these ticks upon a small animal, the amount of blood loss can be devastating. We saw a case when over 60 ticks had attached themselves to a golden retriever which was extremely anaemic and close to death, but received treatment in time to be saved.
Ticks, tiks or tics, yes there are many ways of spelling that short word and just like the pronunciation of a vase, people will argue the correct spelling.. In any case, for arguments sake we will use the most commonly accepted spelling, TICKS. Ticks are small arachnids, ectoparasites (external), which live on the blood of mammals as well as birds, reptiles and even amphibians!
Ticks will burrow under the victims skin with their head, so when removing the tick it is vital to remove them in the best and safest way without tearing the parasite from its embedded head, this can be dangerous and lead to severe complications.
There are many tick specific tools especially designed to remove the tick in a way that will remove the entire parasite safely and completely.
Without a special tick tool, you can best remove a tick with a pair of pointed tweezers and holding the tick firmly as close to the skin as possible whilst gently levering up from the skin. This will held avoid breaks, infections and avoidable complications. Removing a tick should not be approached lightly, it is vital to get rid of it but just as vital to actually know what you are doing.
Ticks are extremely common throughout the world. In addition to the blood sucking lives of the ticks which can cause many problems in our pets, there are also the paralysis ticks which can kill the victim within hours of attaching itself, these have become common in Australia.
Tick paralysis is the only tick-
The incidence of tick paralysis is unknown.Tick paralysis results from inoculation of a toxin from tick salivary glands during a blood meal. The toxin causes symptoms within 2–7 days, beginning with weakness in both legs that progresses to paralysis. The paralysis ascends to the trunk, arms, and head within hours and may lead to respiratory failure and death. The disease can present as acute ataxia without muscle weakness.
Patients may report minor sensory symptoms, but constitutional signs are usually absent. Deep tendon reflexes are usually hypoactive or absent, and ophthalmoplegia and bulbar palsy can occur.
Electromyography (EMG) studies usually show a variable reduction in the amplitude of compound muscle action potentials, but no abnormalities of repetitive nerve stimulation studies. These appear to result from a failure of acetylcholine release at the motor nerve terminal level. There may be subtle abnormalities of motor nerve conduction velocity and sensory action potentials.Prevention.
No vaccine is currently available for any tick-

Tweezers and slide hooks are most common, the main job is to grab the tick firmly whilst lifting away from the victim.
Dermacentor variabilis, also known as the American dog tick or Wood tick. The American dog tick will attach and bite humans as well as dogs. The adults are brown with white streaks or spots on its back. When full of blood they turn grey and are commonly described as resembling a bean. It is a species of tick that is known to carry bacteria responsible for several diseases in humans, including Rocky Mountain spotted fever and tularemia (Francisella tularensis). It is one of the most well-
American Dog Tick
Amblyomma americanum, or lone star tick, is a species of tick in the genus Amblyomma. Lone Star ticks will attach and bite humans as well as dogs and cats. The adults are brown or tan and you will find a white spot on its back. Lone Star ticks are most common in wooded areas, particularly in forests with thick underbrush and large trees, and can also be found in areas along river banks and creeks. This tick carries and transmits the disease Ehrlichiosis. It is widespread in the United States ranging from Texas to Iowa in the Midwest and across to the East coast where it can be found as far north as Maine.
Ixodes scapularis, known as the Deer, Bear or Black-
This tick will attach to humans, cats and dogs. On the west coast of the USA the black-
The Brown Dog tick attaches to dogs but rarely to humans. The brown dog tick, Rhipicephalus sanguineus, is a species of tick which is found worldwide, but more commonly in warmer climates. This species is unusual among ticks in that its entire life cycle can be completed indoors. This tick is also known as the “kennel” or “house” tick. This tick is found in kennels and homes where dogs live mainly indoors. The Brown Dog Tick does not transmit known diseases.
