There are many reasons why you and a veterinarian may not see eye to eye when it comes to certain care standards or treatment plans. Perhaps you feel like they are not exploring more options for difficult, yet treatable conditions. Maybe you have historically seen different outcomes than what they have relayed to you, and you have a gut feeling that they are treading down the wrong path. Always keep in mind that most veterinarians are trying to do their best. Also consider that there are areas of knowledge where they will have more experience and training, and some areas of knowledge where you may in fact have more information and experience (especially when it comes to the long-term care of intensively bred species such as large breed chickens), and sometimes these two knowledge pools do not fully come into agreement.
In cases such as these, do your best to keep things as cordial as possible. There are very few scenarios where openly disagreeing with your veterinarian about their expertise reaps positive benefits. You can almost always get a second opinion from a different veterinarian in non-emergency situations, but it can be difficult to repair a relationship with a veterinary practice if you ever fight with them. Even if you were completely correct in your assessment, arguing with a veterinarian puts you at a serious risk of your sanctuary’s reputation being damaged among veterinarians in your region. If you are branded as difficult or uncooperative (as unjustified as that may be), you may have a very difficult time ever receiving good veterinary care again, which would be devastating for an organization striving to take the most compassionate care of its residents.
