The recent Vet practise regulation draft copy for 2006

Example: On page 10

States Under s.8 of the Act, under claus 4(1)(a) of the draft regulation states treatment of animals by alternative animal health service providers must not be based on their own diagnosis of the physiological or pathological condition of the animal.
A non-veterinary practitioner will be able to provide alternative treatments so long as the dominant purpose of
their attendance on the animal does not involve diagnosis of the animal's physiological or patholigical condition.
(Of course, any treatment provided must also not otherwise constitute a restricted act of veterinary science)
A non-veterinary practitioner could, for example, treat the animal according to a diagnosis obtained previously from a veterinary practitioner. Alternatively, they could treat the animal according to the owner's own diagnosis.

Accordingly, an animal owner could seek treatment from an alternative service provider on the basis of a diagnosis by a veterinary practitioner. Alternatively, the owner or an employee could present the animal to the alternative service provider with their own diagnosis and ask for treatment appropriated to that diagnosis to be implemented. Such treatment can be legally provided, so long as the treatment does not otherwise involve a restricted act of veterinary science (ie making a diagnosis etc)

Those who seek elsewhere for an explanation of the cause of animal illness are not constrained by the draft regulation. For example, some alternative providers may recommend their treatments based on a diagnosis grounded on behavioural, emotional or spiritual characteristics of the animal - without consideration of any recognised physiological or pathological condition in a scientific sense.
