Heartworms ARE avoidable. 1 easy-to-give pill 1x a month prevents dogs from getting heartworms.

Learn the process of an OCAS Sponsored Heartworm Treatment.

Meet Cooper our first OCAS sponsored heartworm case.

This sweet boy may have been our first, but he certainly won’t be our last heartworm case 🐾

Cooper has officially found his forever home with this wonderful couple, and we couldn’t be happier for him.


While at Orange County Animal Shelter, Cooper tested positive for heartworms. Thanks to generous donations, he received the treatment he needed and a second chance at a happy, healthy life. 


We’re proud to be one of only four hospitals in Orange County, Florida participating in this program.

Although OCAS helps cover part of the treatment, it doesn’t cover everything. Adopters must be willing to commit to the months-long process and cover the additional costs. Due to liability and overall health reasons, adopters that are unwilling to purchase the medications OCAS does not cover, we are unable to offer your dog our services.


Please read below so you understand the entire commitment. 

You will be required to sign an agreement with us to confirm you understand the process. 

Contact Us Today

Do you have a question that isn't covered or need to schedule an appointment? Contact us today to speak with a member of our team.

Get in touch

The work you put in during this process will be repaid by your dog with unconditional love!

What is heartworm treatment?

Diroban is a medication to eradicate both immature and adult heartworms present in a dog's heart and bloodstream. Treatment is stressful on a dog's body. Proper aftercare is as vital as the treatment to avoid the worms from getting lodged in the heart.

OCAS Compliance Agreement

What you signed at ocas

OCAS had you sign a document equal to the one pictured here. This agreement is between you and OCAS. 

If for any reason you decide to re-home the dog, OCAS will not pay for treatment. 

Any questions regarding your contract with OCAS must be directly handled with OCAS. 

Costs that are not covered

You will see on your Compliance Agreement, you agreed to pay for any fees not covered by this program.

We have done our best to be as transparent as possible.

We understand there is a lot of content to process here.

Take your time - your new pet will thank you with lots of love! 


each hospital may be different

We do not price match or compete with other practices. 


Please understand  Pet Alliance and Snip It are 501c3 organizations, their fees maybe cheaper as they receive grants. They are a not for profit business. You should expect longer wait times to get an appointment.


Private hospitals such as Ocoee Animal Hospital and Grand Oaks Pet Hospital are private practices. We both run our hospitals without the luxury of receiving tax deductible donations. 


Please do your research prior to booking an appointment with us. Each option has the ability to help you.

Your First Visit

Establish your new pet as a client

Prior to your arrival, you will fill out a new client form online, sign a waiver acknowledging that you are aware of how this process works (will be sent via email), and provide us with your OCAS adoption paperwork and Heartworm Waiver. 


We do require a $150 deposit to confirm your first appointment. 

Although OCAS allows us to charge a booking fee, we do not. 

The deposit will come off any charges you owe at check out. 


Please bring a fecal sample with you. 


Anyone not in compliance during this entire process must be reported to OCAS. 

Meet Our Team

Our staff is dedicated to providing the best care for your pet. We will most likely grab a few pictures while we are showering your dog with love and care! (As long as you are OK with your new baby being a model!)


Dr. Shah will review the medical records provided by OCAS, do a heartworm test, and prescribe Doxycycline. We do the heartworm test to be 100% sure there was not a false positive at OCAS. Depending on her medical assessment, your pet may need other diagnostics. Each dog is unique. 

Our staff cannot diagnose what your dog may need prior to your visit.  

If you have any financial concerns, please check out our Cherry Payment option to get care now - pay later! 

Pet Health Resources

Doxycycline is started during heartworm treatment to target and kill Wolbachia, a symbiotic bacteria that lives inside heartworms. By eliminating this bacteria, the medication weakens the adult worms and drastically reduces dangerous lung inflammation and blood clotting when the heartworms die.


Additional information can be found by visiting the Heartworm Society website. CLICK HERE 

Your financial part

The only medication OCAS Heartworm Treatment covers is Doxycycline for thirty days.


At your first visit, you will be required to purchase Heartworm Prevention. 

The medication cost is determined based on weight. 

Your pet needs to receive heartworm prevention for its entire life. 

A dog can be reinfected without it. 


WORMS FROM PETS CAN BE CONTRACTED BY HUMANS.


A fecal test will be sent out at your expense. Please bring a fresh sample with you.  

If your pet has worms, you will need to come back to purchase medicine. 

The results are usually back in twenty-four to forty-eight hours.

WHY DO WE NEED A FECAL TEST?

Knowing if a dog has other types of worms (like roundworms, lung worms, hookworms, or whipworms) during heartworm treatment is vital. Concurrent parasites add a heavy physical burden to an already-compromised body, and choosing the wrong medication or timing can trigger severe, life-threatening allergic reactions or shock.


OCAS does give Pyrantel for roundworms and hookworms.

Unfortunately, we have found 98% of our patients are still testing positive once leaving the shelter. 

A fecal test is required to ensure the safety of your pet. Once your pet is done with the medication, you will need a follow up test to confirm the pet is now negative. If you have other pets in the home that have been exposed - such as from sharing a yard, the others may need to be treated as well. 


OCAS does recommend keeping your new pet away from established resident pets for two weeks, this issue is one of the reasons. 

 

We recommend purchasing Flea Preventive as well. Fleas can cause tapeworms.  


If your dog has any other conditions, you are responsible for those costs. 

BEFORE YOU LEAVE

Book ALL of your pet's following appointments. The next one is for two months from your consultation. If for any reason, you switch doctors or return the dog, send us an email to Help@GrandOaksPetHospital.com so we can remove you from our list. 


Anyone not in compliance during this entire process must be reported to OCAS.

Your Second Visit

First heartworm injection

This appointment is to be scheduled two months after your consultation. 


You will drop your pet off with us at apx 9AM. 

Your dog will stay with us for the day as it is important for us to monitor the dog after the injection. Your dog will receive a heartworm test, bloodwork,  exam, and the Diroban injection. 


Your dog will receive a Diphenhydramine and Dexamethasone injection. These injections are not covered by OCAS. We are unwilling to treat any dog without these two injections and the owner purchasing Prednisone due to the medical liability and potential pain the dog can experience. Please understand the injection goes into your dogs spine and the heartworms start to die. We will not in good conscious, risk your dogs well being. 


Diphenhydramine

Is commonly known as Benadryl for Dogs. It is used as a pre-treatment medication to help prevent or reduce the risk of severe allergic or anaphylactic reactions 


Dexamethasone

Is given as an injection alongside Diphenhydramine prior to injecting a dog with Diroban* to prevent severe anaphylactic shock or acute reactions from dying worms.


Prednisone

Is to reduce severe lung inflammation and lower the risk of dangerous blood clots or shock when dying worms break down. 


*Diroban (melarsomine dihydrochloride) is a prescription used by veterinarians to kill adult heartworms. PLEASE CLICK HERE TO READ MORE


We will call to confirm the time for pick up after a couple of hours have past after injection. 


We will shave part of your pet's back and give a dose of Prednisone. 

You will be informed of what time the next dose of Prednisone should be given at home. 

At home

You must restrict the dog's activity to avoid sudden death for the next three months. 


Short leashed walks only, no running or rough housing allowed. Keeping your pet calm and strictly restricting exercise during heartworm treatment is critical because dead, fragmenting worms can lodge in the blood vessels of the lungs, causing a fatal pulmonary embolism (blood clot). When a dog receives injections to kill adult heartworms, the parasites begin to decompose and break apart. If the dog's heart rate increases due to exercise, excitement, or stress, these worm pieces are forced deeper into the tiny blood vessels of the lungs, blocking crucial blood flow.  


We can prescribe sedation medication if you feel it will be needed.

 

You must continue Prednisone for two months to prevent anaphylaxis as the heartworms die off.

Your financial part

Required - Prednisone for a 2 months supply - cost based based on weight.


Required - Heartworm prevention if not already purchased


Required - Diphenhydramine and Dexamethasone injection - cost based based on weight.


Optional - Flea/tick  prevention if not already purchased


Optional - Trazodone  

Trazodone is a prescription human antidepressant often used off-label by veterinarians as a mild sedative and anti-anxiety medication for dogs. It helps keep dogs calm during stressful events like vet visits, grooming, thunderstorms, fireworks, separation anxiety, or crate rest. 


Possibly - If the bloodwork, X-ray, or urine find anything not related to the heartworms, treatment cost is solely your responsibility.

next appointment

Book your pet's appointment for one month from your first injection. If for any reason, you switch doctors or return the dog, send us an email to Help@GrandOaksPetHospital.com so we can remove you from our list.

Frequently Asked Questions

Please reach us at Help@GrandOaksPetHospital.com if you cannot find an answer to your question.

The cost of our services varies depending on the type of service needed. We strive to provide affordable and competitive pricing, and we are happy to provide estimates upon request after our doctor examines your pet. Most prices are based on weight.


Besides what we send in our contract as required, you do not have to purchase anything. We will have you sign an estimate showing you have declined our recommendations. 


Absolutely, we would love to be your primary vet however we do know as one of only four hospitals offering this program, people are driving two hours to receive treatment. We will be happy to send your primary vet your records after each visit - just ask!


Please call us. If we are closed, please consult with an urgent care. You are responsible for any costs to see another vet.


Please download our Vello app. The QR code will be on your receipt. You can also visit our pet portal page on this website for a link. 


YES!!!!!!!!!!!!!!!!!!!!!!!!! Mosquitos can be found in our area year round - which means your dog can be infected year round without prevention. Be responsible - give one pill once a month on the same day. Why risk it??


Yikes, this is just as silly as someone thinking they live in a gated area or their pet only goes outside quickly so does not need prevention. Unless you and your pet live in an isolated bubble - please be responsible and give prevention every single month on the same day. Your pet relies on you to do what is in their best interest. 


Yikes, again... one safe pill a month or a long painful ordeal killing the worms - take your pick!  


Only heartworm prevention products that are tested and proven effective by the U.S. Food and Drug Administration (FDA) should be used. 


You need to consult your veterinarian, and immediately re-start your dog on monthly preventive—then retest your dog 6 months later. The reason for re-testing is that heartworms must be approximately 7 months old before the infection can be diagnosed.
