Mange prevention
Mange is caused by mites burrowing into the skin. Two types affect Florida dogs.
Demodex mange is from mites that normally live on all dogs. When the immune system weakens (puppies, seniors, sick dogs), the mites multiply and cause hair loss in patches, often around the face and front legs. Not contagious. Treated with prescription medication (usually Bravecto or NexGard at higher doses).
Demodex usually clears in 2–4 months with treatment. Some dogs have a single episode; others have recurring outbreaks throughout life.
Sarcoptic mange (scabies) is more aggressive — extremely itchy, spreads to humans and other dogs, and causes severe skin damage if untreated. Florida wildlife (raccoons, foxes) carry it, and dogs that hunt or roam can pick it up.
Symptoms of sarcoptic mange: intense itching (worse than fleas), hair loss starting on ears and elbows, crusty skin, secondary skin infections.
Treatment: ivermectin or selamectin under vet supervision. Environmental decontamination required.
Most Florida groomers will refuse to bathe a dog with suspected mange. Demodex can be groomed (with notification to the salon); sarcoptic must be diagnosed and treated by a vet first.
Prevention: regular vet checks, immune support for at-risk dogs, and avoiding wildlife contact. Many of the same monthly oral parasite preventatives that prevent fleas and ticks also prevent mange mites.
