At Deer Grove Animal Hospital in Palatine, IL, our Veterinarian takes the time to do a head to tail consultation to ensure your pet is in great health!







A wellness examination is an important part of preventive health care for pets in all stages of life. If your pet seems to be young and healthy, a wellness examination is a good way to detect changes such as weight gain or loss, dental disease, or other subtle changes that may not be evident at home.


Microchipping is offered both outside of and during surgical procedures.  It is an easy procedure which involves inserting a tiny chip the size of a grain of rice under your pet’s skin between its shoulder blades.  It can’t be removed or fall off and is no more painful than any other vaccine or injection.  Microchipping serves to identify your pet if it is ever lost or stolen.  Only about 22 percent of lost dogs that entered the animal shelters were reunited with their families. However, the return-to-owner rate for microchipped dogs was over 52 percent.  We use Datamars Microfindr microchips because they are manufactured in accordance with ISO standards 11784/5 and the PetLink registration is included in the cost of the microchip implantation, no hidden or annual fees. 


We utilize the safest vaccines on the market for your pet at our animal hospital in Palatine.  We offer three year and one year Rabies vaccines based on the age and needs of your pet.  We also offer thimerosal free vaccines.  Any pets with vaccine sensitivity are treated appropriately and flagged in our system to prevent any unnecessary vaccine reactions.


Deer Grove Animal Hospital is a state of the art laser surgery center.  Surgeries are performed using a CO2 laser.  Laser surgery benefits the patient as there is less bleeding, less risk of infection, less pain, less overall surgery time, and a quicker recovery time. You can rest assured our vets have the experience and understanding needed to give your pet the quality care he/she deserves!


Our animal hospital is equipped to provide diagnostic and therapeutic services to care for your pets’ complete health care needs.


We utilize a state of the art digital radiography system which allows for x-ray enhancements and better x-ray quality.  This allows us to process radiographs faster, more effectively and is better diagnostic tool.  It is less stressful for the patients and helps us diagnose faster and accurately.



Dental Care is important for the health of your pet.  We encourage taking care of your pets teeth.  Untreated dental conditions and dental disease can lead to many problems including pain and stress due to a toothache or sore gums, periodontal disease, a painful disease which causes tooth loss and infections, and left untreated, bacteria can enter the bloodstream and cause other internal organ damage.  Brushing your pet’s teeth is the first line of defense, but regular cleanings are recommended as well.  We perform dental cleanings and extractions using a prestige dental station system.

At our animal hospital we want to ensure a peaceful and comforting experience for both Patient & Client during this difficult time.  We want you to have the peace of mind that your pet has been treated with the utmost care during the entire process.  Therefore, we have partnered with Chicago’s most trusted pet cemetery and crematorium, Hinsdale Pet Memorial Services.

I've taken both of my cats here and they were honest and open about what would be needed and the pricing. We love the care the Dr. shows when with our cats. Would recommend this clinic to anyone with a pet.

We have been coming here since she was a puppy.

We completely trust Dr. Flaven. We have been going to DGAH for years. He is carrying on the torch of the previous Dr. He is very knowledgeable and talkes the time to explain and answer any of your questions or concerns. You can tell he loves animals and cares for them like his own.
