Lyme Disease

Lyme disease is caused by exposure to a spirochete bacteria (double-membrane, asexual bacteria that is cylindrically shaped). Infection carrying ticks spread Lyme disease to pets, generally canines, by attaching to the pet and feeding on their blood for an extended period of time. This bite transmits the bacteria from the tick to the pet. Ticks that carry Lyme disease are most common in specific geographic areas - the Northeast, mid-Atlantic, and upper Midwest regions; they also thrive in temperatures above freezing, so more cases are reported during the months of March through October. After feeding on an animal’s blood supply for several hours, it can take weeks to months for the bacteria to self-replicate and travel through the bloodstream and embed itself in muscles, joints, tendons, the heart, and lymph nodes.

Some pet breeds can develop a fatal type of Lyme disease that specifically attacks their kidneys. Because Lyme disease can be fatal if left untreated, we recommend contacting the veterinarian when you first notice something might be wrong with your pet. For pet owners who live in high-risk areas, vaccination is highly recommended.

Symptoms of Lyme disease in domestic pets: 

  • Decreased appetite 
  • Depression
  • Diarrhea
  • Fever
  • Hesitant to get up from resting position
  • Hesitant to run, jump, or walk
  • Lethargy
  • Limping on one leg then shifting to another
  • Occasional or permanent inability to bear weight on a limb
  • Swollen, painful joints
  • Swollen lymph nodes
  • Vomiting
  • Weight loss

How is Lyme disease treated?

Lyme disease is often extremely difficult to detect. When the veterinarian suspects a patient to have contracted the bacteria, its blood will be tested. It takes most animals 1 to 5 months to exhibit symptoms of an infection after becoming contaminated, if they show outwardly signs at all. Often, pet owners bring in their animal to address another issue; after blood tests are conducted, they are surprised to learn their pet has Lyme disease.

Once your pet has been diagnosed with Lyme disease, it can be treated with oral antibiotics that are administered daily for a period of 4 weeks. If the disease has progressed to the point of causing kidney damage, more powerful antibiotics might be necessary, and hospitalization can be required. Reoccurrence can happen, though it is rare. In these instances, the disease is managed with antibiotics for an extended period of time.

Please contact our office if you would like more information on the dangers of Lyme disease or if you wish to schedule a vaccination appointment.

Here's a vet that still cares.
Just wanted to say I love Dr. Petcu's staff and his compassionate , caring way of taking care of my dogs.The staff is not only friendly and professional ,they know who you are when you arrive ,and they actually love animals. Is the first Animal Hospital that my dogs are at ease and feel comfortable.The place is very clean and the reception area very elegant and inviting. Exquisite services and Dr. Petcu always take his time to explain the disease and options and still finds time to play with my dogs. He's always treated both his animal and human patients with compassion and dignity,and would never recommend procedures unless he truly feels your pet will benefit from it. One of the vets that cares for your pet. The prices are reasonable and the services exceed all expectations. I Highly recommend Dr.Petcu and his hospital.

Western Animal Hospital AMAZING! Western Animal Hospital is the best place in the valley .The staff is professional, friendly, caring and accommodating. The hospital is very clean and upscale. The customer service and the provided services are outstanding.Dr. Petcu is one of the most professional veterinarians that i have ever met in my 25 years of pet parenting. I drive across the valley just to see him( i live in Anthem) .He really cares about his animal patients and it shows in every visits . He is very knowledgeable , compassionate, friendly and always takes the time to answer any question i have and explaining in detail any situation we are dealing with. I had my share of visits to many animal hospitals in the valley but none of them had the last technology as Western - digital X-ray ( they send you home with a cd for you x-ray records ) every room has a computer monitor where the x-ray shows and Dr. Petcu can review with me every detail of it. Also they have the laser surgery and digital dental x-ray. Dr. petcu is one of the most
courteous and pleasant Vets I have ever met. The prices are more than reasonable and also they try to accommodate everybody. I cannot recommend them enough. You can rest easy knowing your pets are in their care.I STRONGLY RECOMMEND THIS HOSPITAL - THEY HAVE A CUSTOMER FOR LIFE IN ME! very good !

He was always helpful, many times we did not have the funds to treat our pets but he was fine with us paying when we had the money. He saved our cats in many instances and all I have to say is that I greatly reccomend Western Animal Hospital for any responsable pet owner .
