We Have the Answers to Your Questions

At GreenTree Animal Hospital, we get a ton of interesting questions from pet parents. Below are some common FAQs that might help answer any questions or concerns. Please feel free to call us at 847-680-6543 for any other concerns you might have about your pet.

What kind of pets do you treat?

Do I need to make an appointment?
Yes, our veterinarians see patients by appointment only. If you feel your pet needs veterinary care and you have not booked an appointment previously, please give us a call so we can assist you and your pet.
Do you offer boarding, grooming, or daycare?

Medicine is what we do best. We can offer suggestions for these services based on client and employee referrals.

Do I have to vaccinate my pet?

Yes and no. State and County require that your cat or dog is vaccinated for Rabies, as this is a matter of public safety. If your pet were to bite someone or another animal, they are required to quarantine, and the type of quarantine is based on their vaccination status. Fines from the County may also be incurred if your pet is not properly vaccinated for Rabies. Other vaccines are considered either core or elective. We also offer vaccine titers if you prefer minimal vaccinations throughout your pet’s life.

Is it REALLY necessary to give my cat or dog flea, tick, and heartworm prevention year-round?

Our weather is unpredictable, and even in the winter, we experience warm days. Flea, tick, and mosquito activity decreases with cooler weather but require freezing temperatures over a sustained number of days for them to die. Intestinal parasites are a year-round occurrence, and heartworm prevention also keeps these parasites under control. Click here to learn more about our preventive care.

My pet has this problem a month ago, can’t I just get the same medication?
It depends on the problem, but most likely, we are going to require your pet to be seen again, even if they were diagnosed and treated for the same medical condition recently. Some medical conditions look similar, and by assuming it is the same condition, we may not be treating your pet appropriately. Certain medications may also result in resistance which can cause a lack of response or, worse, a more severe problem if given too frequently or inappropriately. An exam to ensure proper diagnosis is what is best to keep your pet healthy for years to come.
