Rabies Prevention Tips for Dog Owners

An accomplished veterinarian with many years of experience in the field, Dr. Joel Todd Leroy Prince currently works as a partner with the Elmhurst Animal Care Center. Throughout his career, Dr. Prince has treated dogs with a wide variety of illnesses. A viral illness that acts primarily on the central nervous system, rabies is a particularly deadly disease that spreads via bite wounds and open scratch wounds.

Although many small animals die from rabies every year, pet owners can take several steps to protect their pets from the disease. First, pet owners should always keep their pets’ rabies vaccination up to date, which typically requires a visit to the veterinarian at least once every three years. For individuals with financial restrictions, many humane societies and animal control agencies offer free or low-cost vaccination options. If a pet does receive a bite or scratch from an unknown animal, pet owners should contact their veterinarian immediately. In some cases, a veterinarian can administer a rabies booster, which decreases the likelihood of contracting the disease.

Benefits of Companion Animals

A graduate of the University of Illinois, Dr. Joel Todd Leroy Prince is board certified in small animal practice. With more than 25 years of experience, he is currently a partner at Elmhurst Animal Care Center in Elmhurst, Illinois. A specialist in orthopedic and soft tissue surgical procedures, among others, Dr. Joel Todd Leroy Prince is also an expert in preventative care for companion animals.


Companion animals can fulfill a range of needs, from service dogs that help blind people to animals that help people cope with anxiety. Companion animals have also been shown to have significant psychological and social benefits. Psychologically, whether the patient is a child, an adult, or a senior, companion animals have a positive effect on reported symptoms of depression and self-esteem. Studies of patients with Alzheimer's found that they had fewer episodes of agitation and aggression, in addition to increased appetite and social skills, during the trial period with an animal.

Companion animals have been proven to increase social interaction, particularly in relation to patients with visible disabilities who may have otherwise been avoided. Children with companion animals are also more likely to engage in social activities like clubs, hobbies, and sports.

Lymphosarcoma in Cats

A board-certified small-animal veterinarian, Joel Todd Leroy Prince, DVM, maintains a particular professional focus on oncology. In caring for cats with lymphosarcoma, a type of cancer of the lymphocyte cells, Dr. Joel Todd Leroy Prince draws on more than 30 years of experience and extensive continuing education.

Also commonly known as lymphoma, feline lymphosarcoma makes up 33 percent of all tumors and 90 percent of cancers of the blood in cats. It is one of the most common feline cancers and often develops as a result of feline leukemia virus (FeLV) or feline immunodeficiency virus (FIV). It can affect cats of any age and is extremely difficult to eradicate. For this reason, treatment for feline lymphosarcoma focuses on improving quality of life and encouraging remission.

Most cats with lymphosarcoma undergo four to six months of weekly multidrug chemotherapy, a treatment potentially combined with surgery to remove tumors. If treatment succeeds in achieving remission, the patient's veterinarian may extend the time between treatments to biweekly. After one year, the cat only requires treatment every three weeks, and after 18 months the veterinarian may be willing to stop treatment. Unfortunately, only 10 to 15 percent of treated cats reach this point, but chemotherapy allows even those not achieving permanent remission to enjoy an improved quality of life.

An Overview of Patent Ductus Arteriosus

A diplomate of the American Board of Veterinary Practitioners, Joel Todd Leroy Prince, DVM, has three decades of experience in small-animal veterinary medicine. In his role as a practitioner at clinics in Naperville, Elmhurst, and Glen Ellyn, Illinois, Dr. Joel Todd Leroy Prince focuses on soft-tissue surgical procedures for the treatment of such conditions as patent ductus arteriosus (PDA).

PDA is a treatable congenital heart defect that affects an animal’s blood flow. Prior to birth, an animal’s ductus arteriosus remains open, pumping blood past the lungs because the lungs are not fully developed and cannot yet oxygenate the blood. PDA develops when this blood vessel fails to close as it should after birth. The condition causes blood to divert abnormally back into the heart, forcing the heart to have to work harder than it should to pump blood to the rest of the body. Detecting PDA early is crucial to prolonging an animal’s life, as the condition will eventually lead to heart failure.

In young animals, PDA displays few to no symptoms other than a loud heart murmur detectable by a veterinarian. After diagnosis, a veterinarian will perform soft-tissue surgery to close the vessel using a suture. Animals who receive this surgery generally experience a much better long-term prognosis than those with untreated PDA.

Prevalence and Risk Factors of Canine Osteosarcoma

Dr. Joel Todd Leroy Prince, a board-certified small animal physician, practices in several offices in and around Elmhurst, Illinois. Dr. Joel Todd Leroy Prince maintains a particular focus on the diagnosis and treatment of animal cancers.

Osteosarcoma, or bone cancer, stands out as the most common form of tumor in dogs. It is particularly prevalent in large breeds and in dogs of middle age and older, 7 years being the median age of onset. The condition is also more prevalent in male dogs, whose risk is 20 to 50 percent higher than that of female counterparts.

Statistics suggest that certain environmental exposures and individual medical history may correlate with an increased risk of osteosarcoma. Dogs with a history of rapid growth in puppyhood have a particularly high risk of developing the condition, as do those who have had metal implants or healed fractures.

Some studies have also linked osteosarcoma to genetic factors. A number of dogs with the condition have abnormal variants of the p53 gene, which is active in the suppression of tumors, while DNA and RNA viruses have also proven themselves to be triggers of the disease. Results are not conclusive, however, and more research is necessary to confirm any potential genetic link.

Routine Medical Checkups for Dogs

A partner at Elmhurst Animal Care Center in Elmhurst, Illinois, Dr. Joel Todd Leroy Prince has provided preventive care and treatment for countless small animals. A member of the American Veterinary Medical Association, Joel Todd Leroy Prince, DVM, is an advocate of routine medical checks for dogs.

During a physical examination, the veterinarian will observe the general appearance and physically assess specific areas of your dog. He/she will do this by taking your dog’s temperature and also looking at its skin and coat, both of which are indicators of your dog’s health.

Your veterinarian will also examine your dog’s ears to detect any infections and allergies. The veterinarian will then place his/her stethoscope against your dog’s chest, paying close attention to respiratory movements and heartbeat. Additional checks involve the vet evaluating the abdomen and also looking in the dog’s mouth to investigate oral hygiene.

During a routine medical examination your veterinarian will also ask you questions about your dog’s diet, exercise, thirst, breathing, behavior, and habits so as to ascertain your dog’s medical history. Finally, your veterinarian might also recommend that a sample of your dog’s bowel movements be examined as part of the checkup.

Pets and Antifreeze Poisoning

Dr. Joel Todd Leroy Prince has been a practicing veterinarian since 1984. At Elmhurst Animal Care Center in Illinois, Dr. Joel Todd Leroy Prince continues to advise animal owners on pet health care, including how to protect their pets from common household hazards such as antifreeze.

Among poisons found around the home, antifreeze is one of the most deadly to cats and dogs. Just five tablespoons of the substance can kill a dog, and a cat can die from consuming much smaller amounts. To keep animals safe, store antifreeze in a tightly closed and secure container, and keep a close eye on outdoor surfaces near cars, as antifreeze can leak out.

In the case that a pet does accidentally ingest antifreeze, get immediate medical attention. Common signs of antifreeze poisoning include grogginess and lethargy, which typically appear half an hour to an hour after consumption. This gives way to another phase of symptoms, which include throwing up and kidney failure. Take action without delay to give your pet the best chance of recovery.

Caring for Dogs - Seniors

Dr. Joel Todd Leroy Prince treats dogs ranging in age from puppies to seniors through several veterinary practices in Illinois. In fact, Dr. Joel Todd Leroy Prince is one of very few diplomates with the American Board of Veterinary Practitioners in the state.

Since small dogs tend to live longer than large dogs, determining when a dog enters its senior years can depend on the breed. For example, for a small dog, reaching age seven is roughly equivalent to a human reaching age 44, but for a big dog, age seven is more like 56 for a human. Usually, large dogs hit their senior years at about six, while small dogs begin theirs at about seven.

Like with humans, as dogs age, they become more prone to develop such diseases as cancer and arthritis. Pet caretakers can take steps to protect the health of their older animals. It is very important, for instance, that older dogs see their veterinarians on a regular basis, at least annually. Moreover, caretakers should feed older dogs good food formulated to support animals of their age and activity level.
