Do not squeeze, agitate or forcibly remove the tick since it will be more likely to inject its saliva into you. Hold the ether containing spray about 1cm above the tick and spray the tick 5 times.
The tick should die and drop off in about 5 minutes. After a few minutes, check to see if the tick is still moving its legs, by using a magnifying glass. If the ticks legs are not moving it is dead. Do not jerk or twist the tick. Don't use methylated spirits, kerosene, petroleum jelly, nail polish, oil or alcohol, or use a lighted match. These don't work and may cause the tick to burrow deeper into your skin.
If you are allergic to ticks, do not try to remove the tick — kill it with a spray that contains ether. If it's your first allergic reaction, go straight to a hospital emergency department. If you have had allergic reactions before, talk to your doctor about how to remove the tick and whether you will need to see a doctor every time.
Always carry your adrenaline autoinjector. See your doctor if you can't remove a tick properly and part of it is still left in your skin. You should also see a doctor if you develop signs of an infection, such as:. Tick bites can sometimes cause other illnesses such as rickettsia infections, Queensland tick typhus, Flinders Island spotted fever and possibly Lyme disease or Lyme disease-like conditions. However, whether these are linked to a tick-born illness in Australia is still being investigated.
See your doctor if you have had a tick bite and you experience any of these symptoms for more than a week:. Learn more here about the development and quality assurance of healthdirect content.
Freeze it; Don't squeeze it! That's the latest advice from experts to Australians who have an attached adult tick. Tick removal: First aid and prevention. Read more on myDr website. Read more on Department of Health website. Allergic reactions to ticks range from mild with large local swelling and inflammation at the site of a tick bite to severe anaphylaxis. To prevent allergic reactions to ticks do NOT forcibly remove the tick.
The options are to: Seek medical assistance to remove the tick; OR Kill the tick first by using a product that rapidly freezes the tick, to prevent it from injecting more allergen-containing saliva, then remove it as soon as practical and in as safe a setting as possible.

Unfortunately, Mendel worked in relative isolation and his ideas, although published, were not widely seen by others. Several years after his death the principles of inheritance which he discovered were independently re-discovered by others.
In the process of reproduction, dogs pass genetic information contained within sperm and eggs to their offspring. Examples of such characteristics would be color, pattern, presence of white and copper trim, and such genetic diseases as Collie Eye Anomaly and Progressive Retinal Atrophy. Each parent contributes 39 chromosomes to each offspring, making a total of 78 chromosomes per dog. A chromosome is composed of a linear sequence of units of genetic information; each unit is known as a gene.
In the simplest of situations, each gene is responsible for a single characteristic or trait. In the following discussion, the term dog is used to refer to both sexes unless specifically stated otherwise. The trait of flower color that Mendel studied in pea plants is controlled by the activity of a single gene with two variant color forms.
The Australian Shepherd parallels this as the base color of Aussies is also controlled by a single gene at a location known as the B locus with two variant forms alleles , black and red. The appearance of the dog is referred to as its phenotype and an Aussie is either phenotypically black or red.
Merle versus solid pattern is controlled by a separate gene and will be discussed later in this article. A merle is either a black or a red dog because color and pattern are separate traits. The black color phenotype is due to the presence of at least one copy of the dominant black allele B while the red phenotype is due to the presence of two copies of the recessive red allele b.
While the appearance of a dog is known as its phenotype, the genetic makeup of the dog is known as its genotype. Each dog actually carries two alleles for color — one contributed by its sire, and one contributed by its dam. On the other hand, due to the recessive nature of the red allele b , a red dog is always known to have the bb genotype. This is a closeup of the leg of Hamilton Stage Struck "Levi". He's a black tricolor with generous ticking on this portion of his leg.
You can clearly see where the black of the body ends and the tan of the lower leg begins. The generous smudges in the white paint reveal where black gives way to tan underneath. He is generously ticked and his true color is clearly visible in the tick marks. Notice how the tick marks become tan on his muzzle, throat and eye spots where his tan points should be. On the body they are black, as one would expect with a black tri.
His piebald spotting pattern is nonstandard for the breed, but it does really illustrate the point that tick marks reveal whatever color is under the "white paint". This Aussie, photo courtesy of Peggy Faith, is a piebald pattern white black bi with very generous ticking. He has no tan points, so all his tick marks are black.
