@ellielo have you ever had to enforce one of the contracts in court. I am curious about their outcome as I am aware of some that went to court but did not work out on the basis of environmental conditions, owner behavior, etc.

Diatomaceous Earth (DTE) is a natural and effective way to treat fleas on dogs. Here's how you can use it safely:

• Choose Food-Grade DTE: Ensure you use food-grade diatomaceous earth, as other types may contain harmful chemicals.
• Apply to Your Dog's Fur: Sprinkle a small amount of DTE onto your dog's fur, focusing on areas where fleas tend to hide, such as the neck, ears, and tail. Gently massage it into the fur, avoiding the eyes and mouth.
• Let It Sit: Allow the DTE to remain on your dog's fur for at least 24 hours to effectively dehydrate and kill fleas.
• Brush It Out: After 24 hours, brush out the DTE from your dog's fur. You may need to repeat this process every few days until the fleas are eradicated.
• Treat Your Home: To prevent reinfestation, sprinkle DTE on carpets, furniture, and bedding. Leave it for a few hours before vacuuming.
• Monitor Your Dog: Keep an eye on your dog for any signs of irritation. If discomfort occurs, wash off the DTE and consult your veterinarian.
• Consult a Vet: If the flea problem persists or if you're unsure about using DTE, seek advice from your veterinarian.

DTE works by damaging the exoskeletons of fleas, causing them to dehydrate and die. It's a chemical-free alternative, but proper application and monitoring are essential for your dog's safety. 

We use DTE in our animal pens, and where our dogs sleep or lay. Our dogs live outside and there are deer, cats and goats running about and we do not have a flea problem.

About 4 years ago the dog shed had fleas and we treated it with Bifenthrin and that cleared it immediately. Read the label very carefully if you decide to try Bifrenthrin.
