Dr. Clay Dean is moving towards a well-earned partial retirement. He has served the Muscoda area as a large animal veterinarian for over 40 years. From now on Dr. Dean will only be offering services to equine clients and on a selective basis. 

To better serve our current clients, we are limiting our after hours emergency services to current clients in good standing only. We will also be primarily equine emergency after hours. Small animal emergencies may need to be seen at the nearest emergency centers, though we will offer triage services over the phone. We frequently recommend UW-Madison and Madison Veterinary Specialists for 24 hour care. 

We understand that these changes will come as a surprise to our clients and that it may be an unpleasant one. Please know that this decision is being made after months of deliberation and careful consideration. Further changes may occur within the coming months.
