Elena's favorite part of the job is being a reassuring presence for owners in times of uncertainty. When she isn't at work, you can find Elena working on multiple knitting projects, or walking one of her three dogs, Hobson (who if you're lucky, you might see accompanying her around the office). MAH has become a second home to Elena, and she can't wait to greet you with a smile and meet your furry friends when you come in.

How to Safely Remove a Tick from Your Pet

  1. Wear latex gloves to protect yourself.  Use a pair of sharp-pointed tweezers or specially-designed tick removal tweezers to grasp the tick at the point of attachment.  This should be done as close to the skin as possible. 
  2. Be very careful not to squeeze the body of the tick. 
  3. Pull the tick straight out from the skin slowly and steadily using even pressure - without twisting or turning.  Some of your dog’s skin may come off with the tick. This is normal.  If bleeding occurs, apply light pressure to the area. 
  4. Once removed, the tick should be handled carefully. While some prefer to dispose of the pulled tick, saving the tick for further identification is a good idea.  You may want to place the tick in a small airtight container.  Some rubbing alcohol may be added to the container.  Label the container with the date and store in case future illness occurs, as identification may become necessary. 
  5. If part of the tick’s head still appears to be embedded, use the tweezers to gently pull it out.  
  6. After the tick is removed, clean the bite area with mild soap and water.  Keep an eye on this spot for several days in case of further irritation or infection. If the area does not clear up in a few days or if you have any concerns or questions, please contact MAH at 269-668-3307 and we'll be happy to assist you!


  1. Do NOT use a match or other materials to try to smother the tick or get the tick to 'back out'. This does not work, and may cause the tick to regurgitate more saliva (and potential pathogens) into the skin.
  2. Use a Flea/Tick repellent product on your pet. MAH can help you find a product right for your pet's needs.
  3. Check your pet daily, especially in the spring when ticks are most common.
  4. Discuss your pet's risk assessment of Lyme Disease and the annual Lyme Disease vaccination with one of MAH's veterinarians or staff.


Laboratory Testing

Blood chemistry and electrolyte panels as well as complete blood counts can often be performed during your appointment. These tests are important in evaluating organ systems and blood cell responses. These panels are often performed prior to anesthesia/surgery, to monitor a chronic medical condition, or when your pet is acutely ill. We also offer a variety of other blood tests performed in-house as well as access to Michigan State University and IDEXX labs.  

Digital Radiography

Radiographs (“x-rays”) are often taken during your pet’s appointment to assess the medical and surgical needs of your pet. They are processed in a timely manner so that the veterinarians can discuss optimal treatment with you at the time of your pet's appointment.


Ultrasound is another useful diagnostic tool to non-invasively assess the health of your pet's internal organs.


Dental care is an essential part of the overall health of your pet. While under anesthesia, your pet receives a complete oral exam. The teeth are probed, scaled and polished, a dental chart is completed, and x-rays are taken as needed. Once the x-rays are reviewed, oral surgery may be needed to remove abscessed, worn or broken teeth. Advanced cases needing endodontics, such as root canals, may need to be referred to a local specialist. 

Anesthesia Monitoring

Any anesthetic and surgical procedure involves some level of risk. In order to monitor the patient as carefully as possible, we utilize a pulse oximeter that measures the blood oxygen level during surgery. A Licensed Veterinary Technician also carefully observes heart and respiratory rates as well as blood pressure during surgery.

Laser Surgery

It has been suggested that laser surgery results in less bleeding, less pain and faster recovery times.
