Good Morning and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
This is not unsual and Roxey may have had a bad experinece with this in the past so she is afraid of this. Try using Benadryl up to 2 mg per pound 1 hr prior to trying this which will make Roxey drowsy. If this is not enough, your vet will prescribe a tranquilizer called Acepromazine that will allow you to get her used to this so she understands that it will not hurt her.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.
Sincerely, Dr. Loretta
