Hi there. This would not be a common or expected side effect of Bravecto, so I would be suspicious that something else is probably causing the itching and hair loss. If it continues, I would recommend taking Tinker to the vet for an exam. Possible causes would include allergies (food allergies, or an allergy to something in the environment), a bacterial or fungal skin infection, or skin mites (mange). Your veterinarian can do some simple skin tests if needed to help diagnose the problem and get him started on appropriate treatment.
