My dog has flea prevention. Can I still see flea eggs or in clothes?

You can also check for little black specks on his fir closest to his skin called flea dirt. Likely though if you apply flea prevention and the doctor found no evidence he should be ok but if you find these little black specks of dirt, a way to conform if it is indeed flea dirt is take a paper towel, wet it, and smear the dirt specks around. Normal dirt will not look any different after doing this however flea dirt will have a reddish color to it

Fleas require a host like a dog or cat to complete their life cycle. If a flea egg got on your clothing it could hatch, but the flea would then die. Advantage also contains a medication that prevents flea eggs from hatching, so if the flea had been on your pet before it jumped off and died the egg would not hatch.

Unfortunately toward the last week of the month these ampules sometimes wear off, meaning your dog can have fleas and the fleas can lay eggs, but as long as you treat him regularly those eggs and any reaming fleas will be killed.

You should not worry if no more signs have shown and your dog is on a high quality flea preventative. You are doing exactly what you need to do in order to prevent fleas in your home. Keep up the good work!

High quality flea preventatives are very effective, so I would be surprised if your dog is itching from fleas. Different flea preventatives utilize different mechanisms of action to kill fleas. Some preventatives work by killing the flea after it bites, so it is not unheard of to see one rare flea. The important part is that the flea is killed before it has a chance to reproduce and lay eggs. The next time you see dirt on your dog, try to put it onto a white paper towel and moisten it slightly. Flea dirt becomes a reddish-brown color when wet. If you do not notice a significant color change, it is just regular dirt. The dandruff may be appearing as a result of skin sloughing when your dog itches. Allergies to a wide variety of environmental influences and food are a common cause of itching in dogs. Consider discussing this intense itching with your vet because dogs can develop skin infections by introducing bacteria or yeast from excessive scratching.

Why take the chance? just treat your dog with a high quality flea preventive treatment and then you can rule out fleas, that is the only way to rule it out completely as fleas and eggs can be missed by the naked eye.

The best way to determine if the dark specs are 'dirt' versus 'flea dirt' is to collect the specs on a clean white paper towel and apply hydrogen peroxide. If it turns rusty colored, it likely flea dirt. Flea eggs are very small and you are not likely to see those with the naked eye. Also, the best place to look for fleas is on the lower back and between the hind legs on your dog. If you determine that you are seeing fleas or evidence of fleas, I would recommend talking to your veterinarian about switching flea products. Hope this helps.
