It is essential to consult a vet for flea infestations if you are unable to control them with over-the-counter products or home remedies. Additionally, if your dog is experiencing severe itching, skin irritation, hair loss, or if you notice any signs of anemia such as pale gums, it is crucial to seek veterinary help. Vets can provide prescription-strength flea treatments that are more effective than over-the-counter options. They can also offer advice on preventing future infestations and check for any underlying health issues that may be contributing to the problem.
