How to Choose the Best Flea Treatment for Dogs?

Check your dog’s size

When looking for the best flea treatment for dogs, the main thing you should consider is your dog’s weight and size. For example, if you have a puppy, you shouldn’t buy a product designed for large dogs. This is because using larger quantities might lead your dog to become ill or to experience unexpected side effects. 

Examine the infestation’s state

Before purchasing a flea treatment, you should pay attention to how large the flea infestation is. If it has spread to your carpets, drapes or rugs, you’ll need to treat your dog and house at the same time.

Understand ingredients

You need to become familiar with the components that are used for flea medicines. This will decrease the opportunities for allergies or other effects in your dog and even yourself. Here are some common ingredients you should know: fipronil, S-methoprene, permethrin and pyriproxyfen.

Take note of your dog’s sensitivity level and potential allergies 

As a dog owner, you have to check your dog’s response to the flea treatment all the time. If he is susceptible to inflammation, it would be better to opt for tablets rather than topical applications. If he has any itchy red places or patches of skin with hair rubbed off, he’s probably allergic.

Read the instructions carefully

No matter which best flea treatment for dogs you’re going to purchase, please first read all the directions for application and make sure you understand them all before using the product. Avoid using any therapy meant for dogs on cats and vice versa because it may result in dangerous issues for your pets.

Don’t forget to ask your veterinarian

Your vet can provide specific suggestions that he thinks will be useful for your pet. His advice is especially vital if your dog is old, sick, lactating or pregnant. 

To Sum Up

Now, you have a lot of information to help you choose the best flea treatment for dogs. Remember that the sooner you treat the problem, the easier it will be to handle. Although all the products I have suggested here are good, my favorite is Bayer Advantage II Topical Flea Treatment. Firstly, because it can kill fleas, eggs, and larvae within minutes. Secondly, it prevents flea populations and breaks their life cycle. Thirdly, its effectiveness lasts up to 30 days. That means you can totally set your mind at rest when using this product.
