Most professional Pets Grooming West Hollywood CA will have an information sheet for you to fill out. It should ask basic questions about your dog and any health problems or allergies he may have. It should also ask who you would like contact in case of an emergency. An emergency at the grooming salon is rare but it is important that they know what vet your dog should be taken to if there is a problem and who should be called. They should also ask about your vaccination records and will need proof of your dog’s rabies vaccination. If a groomer does not ask about any of these things I would look for a different groomer.
