For Our Breeder Clients

As a center for canine reproduction, we will always do our BEST to be available to you for emergency c-sections or whelping no matter what the time or circumstance, as long as PRIOR NOTICE of a possible need is given during normal business hours.

Although we have a wonderful and accommodating staff, there are rare occasions when we are unable to pull our staff together at odd hours due to sickness, weather conditions, continuing education, etc.

We therefore suggest calling our hospital and speaking to the veterinarian on call to formulate a plan in case of emergency. Appointments may be scheduled outside of the hospital’s regular office hours for procedures that cannot wait. These should be scheduled directly with Dr. Vali on an as needed basis.
