What To Do When Your Dog Gets Fleas:

"There are many available dog flea treatment options and the choice can be confusing. To cut to the chase, we recommend the dog flea medicine Advantage. This product has an active ingredient that keeps dogs free from fleas, eggs and larvae. It prevents eggs from hatching and larvae from becoming adult fleas. It is not toxic to any mammals such as dogs or cats (only buy products marked for dogs if using with dogs).

There are three categories of dog flea treatment options:

  • Spot-ons that are applied to the skin at the back such as Advantage, Frontline and K-9 Advantix: provide lasting protection. These product have more longevity.
  • Shampoos and Collars: Shampoos are good for a quick fast-acting treatment, but do not provide residual protection. We do not recommend collars since they offer protection up to 2 weeks and protection can be limited to the area around the collar.
  • Oral tablets: Another good option, particularly in dogs that are suffering from a large infestation. Longevity varies between products.

We do not recommend flea bombs, foggers, or garlic for fleas. Garlic has not been proven to work and if you need a fogger, it is best to call an exterminator.

Dog flea treatment is necessary the second you suspect that your dog has fleas. Infestations are common when the weather gets warm.  Fleas create discomfort for your dog and can lead to alopecia (hair loss), skin problems (dermatitis) and tapeworm.  Fleas can also be harmful for people living in the home since they can spread bacteria.  

Treatment for fleas on dogs is also necessary to keep them from spreading throughout your home since a flea can produce up to 50 eggs everyday and can lay 2000 during the fleas life. A veterinarian can prescribe a one time medication called oral nitempyran that can kill fleas within 15 to 30 minutes after being taken.

Symptoms such as itch can be addressed with prescription antihistamines and corticosteroids that can be taken via an injection or by mouth. If your veterinarian recommends "isoxazoline class" such as Credelio, Simparica, Nexgard and Bravecto as about rare. Adverse neurological events include muscle tremors, seizures and ataxia (loss of control of body movements.)  

When you discover fleas vacuum and disinfect the home and wash the dog's belongings. Consider treating belongings with a plant based flea spray for maximum safety."

Killing Fleas at Home

Fleas can leap from a dog to people and can contaminate a house.  Start by thoroughly vacuuming all areas where your dog has wandered.  Dispose of the vacuum bag outside of the home immediately after vacuuming them up. For added protection in the home consider a safe environmental spray designed for indoor use such as Benzarid.  It uses benzalkonium chloride as the active ingredient to kill any remaining fleas in the home.
