Featured Product:
Summit Joint Performance 

Q. What is Summit?

A.Summit Joint Performance® is the purest form of Chondroitin 4 Sulfate ever developed. It is a naturally derived, low molecular weight, compound and is the most effective and safest Chondroitin product available on the market today. Summit was developed by doctors and scientists for use in human corneal transplant surgeries. Later it was discovered to have incredible effects on the joints of horses when delivered via intramuscular injection.

Q. What is the injection protocol for the loading dose of Summit Equine?

A. Give one IM (intra-muscular) shot every 7 days for 4 weeks. After the loading dose, most horses will be able to switch to a once-per-month dosing schedule. High performance horses in heavy competition can benefit from using Summit more often. Many top-level horses on a Summit regimen use it once a week.

Important COVID-19 Information

As COVID-19 continues to spread across the globe, Fox Valley Equine is committed to providing care for our clients and their horses. We are prepared to continue business as usual at this time. To protect the safety and wellbeing of our clients, staff, and veterinarians, we will be implementing some precautionary changes to mitigate the risk of exposure of COVID-19.

1.       We have asked any staff and veterinarians experiencing illness/symptoms to stay home and seek medical care.  

2.       If you have an appointment scheduled or have an emergency with your horse and you are exhibiting flu like symptoms, have recently been exposed to COVID-19, or would prefer to not be present at our visit we ask that you alert our staff.  We will bring enough help to meet your horse’s needs while communicating with you electronically. 

3.       We are instituting a no-handshake policy at this time to help limit potential spread.  

We appreciate your patience and understanding during this time.   If an appointment needs to be cancelled or postponed, we will do our best to reschedule in a timely manner. Our ultimate goal is to ensure the health of our clients, staff, and veterinarians so that we may continue to provide exceptional care to our patients.
