My friend’s dog was recently diagnosed with Lyme disease. I am confused what type of tick causes it. What should I be doing to avoid this happening to my pets? -Sonya Walker of Oil City, PA

Your friend’s dog is not alone! Lyme disease is the most diagnosed tick-borne disease of dogs in the area. Tick populations are spreading due to climate changes and the recent mild winter has led to a particularly early and severe tick season.

Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted through the bite of infected deer ticks, also called blacklegged ticks. The clinical signs of Lyme disease in a dog include fever, anorexia, lethargy, and painful, swollen joints. Signs usually develop within 2-5 months following infection. In some endemic areas, like Venango County, 90-95% of dogs are exposed to Lyme disease but remain asymptomatic.

Lyme disease is treatable with an antibiotic and many dogs with clinical signs show significant improvement within 2 days of starting appropriate treatment. It is most beneficial to start treatment as early as possible once clinical signs appear since chronic changes in joints and other tissues may cause serious and fatal complications if left untreated.

There is no evidence that infected dogs are a direct risk for infecting people except by introducing infected ticks to the house. It is possible for partially fed ticks to reattach and feed, hence becoming a source of infection for people. Direct transmission of Lyme disease from dogs to people is unlikely.

Visit your veterinarian to have your dog screened and vaccinated for Lyme disease. Many products — collars, sprays and spot-on products — are available as tick preventatives. Some are available over the counter, but serious problems may occur when they are used improperly. Please consult your veterinarian before beginning any treatments.

The best way to find ticks on your pet is to run your hands over the whole body. Check for ticks every time your pet comes indoors. Ticks attach most frequently around the pet’s head, ears, and neck, but are by no means restricted to those areas.

My cat’s breath smells horrible. What can I do? Are there dentists for cats? -Greg Host of Tionesta, PA

Greg, you are a very observant cat owner. Bad breath, also called halitosis, is a common complaint among pet owners. The most common cause of halitosis is dental disease caused by plaque (bacteria). Bacteria is attracted to the tooth surface and over time becomes mineralized producing calculus. As plaque ages and gingivitis develops, the bacteria change into types that produce hydrogen sulfide causing halitosis.

Other causes of bad breath include eating foul smelling food, metabolic disease (diabetes, kidney disease), non-periodontal oral disease, foreign bodies, trauma and infectious agents including bacteria, and viruses. A veterinary examination is necessary to diagnose the specific cause of bad breath. If the diagnosis is not obvious after oral examination, blood tests will be taken to check for internal disease.

Daily brushing can help control plaque buildup, but a yearly cleaning under anesthesia will greatly help prevent tooth loss. Having your cat’s mouth and gums evaluated during the yearly examination will address this situation. Bacteria in the diseased mouth can lead to other chronic conditions, such as kidney dysfunction and heart valve problems.

You can visit www.avdc.org to find a veterinarian that specializes in dentistry. Most general practice veterinarians can also perform dental procedures that include a thorough oral exam, dental radiographs, necessary extractions and an ultrasonic scaling and polishing.
