When you or your dog are out enjoying the early Spring weather, be assured that there are tick out too. They are looking for you and your dog!
Thousands of dogs are
infected annually with dangerous tick-transmitted diseases. Within the last few years it has been reported that there has been a 30 percent increase
in the rate of dogs exposed to tick-transmitted diseases.
Ticks are parasites that
attach themselves to dogs, feed on blood and transmit diseases directly into the
dog’s system. Major tick-borne diseases transmitted to dogs in the United
States include:
• Lyme disease, which comes from the deer tick, can cause stiffness, lameness,
swollen joints, loss of appetite, fever and fatigue. Your dog may not show
signs of the disease until several months after infected.
• Canine Ehrlichiosis, found worldwide, is the most common and one of
the most dangerous tick-borne disease organisms known to infect dogs. Caused by
the brown dog tick, symptoms may not surface for months after transmission, and
can include fever, loss of appetite, depression, weight loss, runny eyes and
nose, nose bleeds and swollen limbs.
• Canine Anaplasmosis, also called dog fever or dog tick fever, is
transmitted from the deer tick. Symptoms are similar to other tick diseases
including fever, loss of appetite, stiff joints and lethargy, but also can
include vomiting, diarrhea. In extreme cases, dogs may suffer seizures.
• Rocky Mountain Spotted Fever comes from the American dog tick, the wood tick
and the lone star tick. Symptoms include fever, stiffness, neurological
problems and skin lesions. Typically the illness lasts about two weeks, but
serious cases could result in death.
• Canine Babesiosis is typically transmitted by the American dog
tick and the brown dog tick. Causing anemia, symptoms may also include pale
gums, weakness and vomiting.
• Canine Bartonellosis comes from the brown dog tick. Symptoms are
intermittent lameness and fever. Left untreated, this disease can result in
heart or liver disease.
• Canine Hepatozoonosis is thought to be transmitted by the brown dog
tick and Gulf Coast ticks. Your dog can be infected if he eats one of these
disease-carrying ticks. Symptoms are fever, runny eyes and nose, muscle pain
and diarrhea with the presence of blood.
Not all diseases mentioned here, occur in all parts of the USA.

Prevention & Screening
The three most important actions you can take to prevent ticks are:
1. Use a Preventic collar every 90 days. Put the date on the inside of the collar so you can remember to change it. You can also post it in Outlook or your favorite reminder system.
2. Use a reliable tick prevention product on your dog. Usually, the ones sold by veterinarians work much better than over-the counter products. We use Parastar Plus in the hospital and recommend it.
3. Use Knockout Area Spray in your home every 30 days.
Screening test can be done at your veterinarian during and annual wellness exam for your dog. The one we rely on is the 4DX test which screens for Lyme, Ehrlichiosis, and Anaplasmosis. In addition, it screens for +heartworm disease (see blog for March, 2011)
To confirm a positive finding, a second, more detailed test is sent to a lab before treatment. Those tests could be a Quant C6 for Lyme disease or a Western Blot test.
Symptoms of Tick Borne Disease
Listed below are many symptoms. No patient will have all these clinical signs. My purpose is to alert you that a tick borne disease may be involved. Only you veterinarian will be able to confirm your suspicions.
- anorexia (lack of appetite)
- weight loss
- fever
- lethargy (mild to severe)
- discharge from the nose or eyes (in puppies, sneezing
or clear nasal discharge)
- diarrhea (may contain blood or raspberry gel-like
component) cough-deep or merely hacking
- neurological signs including seizures, repetitive
obsessive/compulsive actions such as chewing fur and/or licking legs,
un-coordination or palsy
- depression
- vomiting bile (yellow and possibly frothy) stained
fluid
- hemorrhaging even when blood count looks normal
- lightening of nose color
- nosebleeds
- blood clotting problems-even with normal CBC (complete
blood count)
- edema (swelling) of the extremities
- muscle wasting
- chronic ear and skin infections that do not respond to
normal treatments
- low platelet count (thrombocytopenia)
- ocular signs including bloodshot and glassy eyes,
anterior uveitis, retinal hemorrhages, dilated pupils, photophobia
- low WBC count (leukopenia)
- elevated WBC count (leukocytosis)
- regenerative or non-regenerative anemia
- arthritis, unexplained lameness in one or all legs
- weakness
- pallor (pale gums or tongue)
- incontinence
- enlarged liver, spleen
- liver, kidney failure
- elevated liver enzymes or kidney function tests
- increased thirst and urination
- neck or back pain
- bleeding under the skin or a rash (purpura)
- enlarged lymph nodes
- irreversible bone marrow suppression
- protein in urine (proteinuria)
- prostatic infections and/ or enlarged prostates in young, intact dogs
Removing Ticks From You Dog
Do not use alcohol, nail polish, hot matches, petroleum jelly, or other methods to remove ticks. These methods may actually traumatize ticks causing them to regurgitate their gut contents. Essentially, you don't want to do anything to make the tick expel its gut contents into the individual or animal--this greatly increases the chance for infective organisms to be transmitted. You also don't want to crush the tick after removal and get the contents of a potentially infected tick on your hands.
- Wear gloves and use a tweezers. Caution is advised
because most diseases that ticks carry can also be transmitted to people.
- Grab the body of the tick with the tweezers and firmly
pull the tick straight out, DO NOT TWIST OR JERK. Do not puncture the body
of the tick.
- If it looks like some of the tick did not come
completely out (the tick's mouth part has a barb on it to make removal more
difficult), use an alcohol sterilized needle to remove the remaining
pieces.
- Cleanse wound with soap and water, and then alcohol.
- Save the tick in rubbing alcohol (the alcohol quickly
kills the tick) for future identification and testing**, if necessary.
Date the bottle. Drowning a tick in water does not work--they can even
survive flushing down
the toilet. - Mark the date on the calendar; this could be useful information if the dog starts showing symptoms consistent with tick disease.
Hope this information helps. Don't get bit!
