Some issues such as metabolic illnesses can cause hair loss and skin darkening. You may also see changes in weight, appetite, water intake, etc. Other potential causes include parasites, allergies, skin infections, etc. Since there is both a change to skin and coat, having Trixie examined by your vet and samples taken or bloodwork done may help narrow down the cause so it can be treated.
