Is it permissible for a female veterinarian who works with pets to adopt the Maliki school's view on the purity of dogs to facilitate her work and prayers, or is this considered following prohibited whims?

An ordinary person is allowed to emulate whomever he wishes from the recognized madhhabs (schools of thought). There is no sin in emulating the Maliki madhhab, which holds the view that the dog's body, saliva, and tears are pure. However, its excretions, such as urine and feces, are considered impure by them and by others.
