Regular wellness exams allow us to catch underlying health problems early, provide consistent preventative care, and support your pet’s overall health and well-being.
Our veterinarians are skilled in diagnosing common problems that affect our pets like vomiting, itching, lumps, limping, and more.
Vaccines are essential for preventive care and can increase the chances of a longer, happier life for pets. Ensuring that pets are consistently up to date with their vaccinations can help prevent contracting disease or help lessen the severity of symptoms if a disease is contracted.
Another key component of helping to maintain your pet’s health and happiness is having them on reliable, consistent heartworm preventative.
Heartworm disease is serious and potentially fatal to our dogs and cats. Heartworms are spread by mosquito bites and can grow up to a foot long, living in the heart and lungs of our beloved pets.
Fleas can cause itchy skin, skin infections, and spread tapeworms. Ticks can carry disease such as Lyme Disease, Ehrlichiosis, and more.
From routine cleanings to tooth extractions, the Thrive Pet Healthcare network of Primary Care veterinarians and Dental Specialists is here to keep your pet's smile fresh! Our general practices can take care of everyday dental maintenance with outstanding regular check-ins, cleanings, and basic surgeries.
Meanwhile, our specialty veterinarians are prepared to handle more complex or chronic dental cases like a root abscess, jaw fracture, abnormal tooth formation, or advanced periodontal disease. These doctors are highly trained within the field of veterinary dentistry and have access to specialized equipment, typically unavailable at primary care clinics.
Unless you intend to breed, we recommend having pets spayed or neutered. Pets that have been spayed or neutered tend to live longer and have healthier lives.
It's hard to provide care without knowing the root of what is ailing your pet, which is why diagnostic testing is so important. Diagnostic testing can include laboratory testing (blood, urine, and fecal) and diagnostic imaging like X–rays, CT, MRI, and ultrasound.
We will be by your side during this time of need to offer both medical assistance and emotional support.
The occasional taps, scrapes, and scratches that happen when playing with your pet means it's time for a trip to your local veterinarian or boarding facility! Trimming your pet's nails is a healthy part of their life, and can lead to greater comfort in everyday activity.
Medical Director, DVM
Dr. Nickless started at Have A Heart Animal Hospital in May 2021. She is originally from Rowley, MA, but went to The Ohio State University for veterinary school and stayed out there for four years. During that time, she worked at a mixed animal general practice, seeing a large variety of animals and also a lot of emergency work. She decided to move back toward the east coast as her and husband decided to start a family, and welcomed their son, Dominic, in January 2022. They have two dogs at home - Disha and Chestnut, four cats - Sarabi, Rafiki, Kylo, and Lyra, two horses - Dots and Desdemona, and 13 chickens at home. Dr. Nickless has a special interest in eyeball cases, behavior cases, and education - both for clients and her support staff! If you have anything you would want her to do a vlog on, send the clinic an email!
