Most veterinary facilities accept payment by major credit cards. This is especially helpful at the time of a medical emergency. I thought my doctor really cared and would go the extra mile for me. The extent of care given to any animal is ultimately determined by its owner. Every pet owner has different ideas as to what is acceptable pet care.
Veterinarians can only make their clients aware of the medical options that are available.
Then, they guide owners in their choices regarding the most important health care options for their pets. The final decision and choices rest with the owner. Not only is it unethical and illegal to prescribe for an animal that hasn't been physically examined by a veterinarian, it is also impossible to come up with an accurate diagnosis and rational plan of treatment. A veterinarian can't make a diagnosis based on symptoms only as observed by an owner. The outward signs may be an indication of any number of internal causes with a wide variety of clinical treatments.
