Laser is an acronym for light amplification by stimulated emission of radiation.

Laser light intermingling with tissue is a special approach to surgery. The laser uses a highly focused laser beam which efficiently ablates the living tissue and seals capillaries, small blood vessels, lymphatics and nerve endings.  This is beneficial to both the patient and surgeon because there is less pain than using a traditional scalpel, less bleeding, less inflammation and better tissue healing.  Since the laser seals the nerve endings when it cuts, it also decreases post op pain as well.  The risk of post op infection is also reduced as the heat from the laser destroy any bacteria present on the tissues during surgery.  We use a brand new state-of -the-art CO2 laser for all surgeries at Deer Grove Animal Hospital.  Click here for more information about laser surgery.

Our animal hospital is equipped to provide diagnostic and therapeutic services to care for your pets’ complete health care needs.  We have an  on-site Abaxis blood analyzing machine to obtain immediate, reliable and accurate results.  We also perform many other tests in house using trusted reliable screening tests like Zoetis Vetscan Rapid tests.


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.

pet wellness exams


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.


Pet dental care is so important for optimal health.  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 pet dental cleanings and extractions using a prestige dental station system. Read more about pet dental care.


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.

Microchipping is offered both outside of and during surgical procedures. 

What is Microchipping?

Microchipping 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. 


Benefits of Microchipping Your Pet

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. 


pet vaccinations


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.

We now perform dental x-rays!  Using a digital dental x-ray machine, we can identify and pinpoint dental problems that cannot be seen on the surface.  It helps evaluate periodontal disease, identify root canal disease, embedded or impacted teeth, tooth fractures below the gumline, feline tooth resorption and much more.

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.

We've been coming to Deer Grove Animal Hospital for about a year now and couldn't be happier. Every person we've worked with has been kind, helpful and willing to answer any questions we have. They treat our pets well and we always feel good after leaving their office. We couldn't recommend Deer Grove Animal Hospital higher for those looking for a quality vet.

Always have an excellent experience here over the last few years. My cats typically don't like strangers at all and they seem to like everyone at Deer Grove Animal Hospital and that is saying a lot. Can't recommend them enough. I also appreciate the changes to their policies they made to keep everyone safe during the pandemic.
