  3. Help to repair skin: Flea and tick shampoos rehydrate, moisturize and soothe skin after your dog has been affected by parasites. Flea bites can cause severe itchiness, dry skin and infection if your dog has been scratching at their skin. Luckily flea shampoos will kill the fleas then heal the skin!

Signs That Your Dog Has Fleas

It’s extremely easy for fleas on pets to go unnoticed. Fleas are tiny, active parasites that feed on your dog’s blood. While fleas tend to be more active in the warmer months, they exist all year round. Your dog can become infested with fleas at any time, so it’s important to know what to look for. Here are some signs that your dog may have fleas:

  • Restlessness
  • Excessive scratching
  • Licking or chewing at certain areas on their body
  • Shaking their head or scratching at the ears

Fleas can be easy to spot if you are looking for them. Combing through your dogs fur will allow you to see the fleas jumping around and moving on their body. Fleas have flat bodies and they take on a brownish color. Their color will become darker as they ingest more blood. Fleas are extremely tiny, ranging anywhere from 1/16 to 1/8 of an inch.

Fleas are attractive to warm, protected areas of your dog’s body such as the groin and armpit area. If those areas look red and bumpy, there’s a good chance it could be fleas. While flea shampoos can kill these nasty parasites and jump start the healing process, it’s always a good idea to seek veterinary advice with specific questions or concerns.

5 Components to Look for in a Flea Shampoo for Dogs

There are several different flea and tick shampoos available for your dog. Every situation is different, but below are some components to take into consideration when choosing the best shampoo for your dog:

  1. Preventative benefits: There are several great flea shampoos that prevent further infestation of parasites. Some even repel mosquitoes! If you want a flea shampoo that will act as a preventative for your dog, check the labeling to see if the choice you’re interested will help with that.
  2. Soothing ingredients: Dogs often end up with inflamed, irritated skin after battling fleas. A good flea shampoo will have ingredients which help rejuvenate the skin. These ingredients include but are not limited to oatmeal, aloe vera and coconut extract.
  3. Conditioning formula: Do you have a dog with long or curly hair? You may want to purchase a 2-in-1 conditioning flea shampoo. Buying a dog flea shampoo with built in conditioner will save you time and money!
  4. Number of baths necessary for proper treatment: While some flea shampoos may only require one wash to completely kill all of the pests, others may need two or three.
  5. Ability to kill lice: Did you know that dogs can contract lice from their canine pals? Some flea shampoos will also kill lice on your pup. It’s always beneficial to have a shampoo that can be used for multiple purposes!
