Don’t let your dog suffer from a painful flea infestation. There are ways to prevent future infestations using the best dog flea treatment products in the market. In this article, we will shed light on useful information including:

  • What are the early signs of a dog flea infestation?

What are the early signs of dog infestation?

It’s not easy to see fleas as they’re very small and will not become obvious until you take a closer look. To help with, the following steps should be taken:

  • Use of a fine-toothed comb and brush to spot any small brown dots moving about
  • Look out for any patches with hair loss
  • If your dog is anaemic it could be an indicator of extensive flea bites
  • Take a keen look at the ears and tail
  • Check for “flea dirt”. Fleas leave their poo on your dog’s fur and to confirm this, put some of it on a piece of moistened tissue and you’ll notice it turns red. This is from the blood ingested by the flea.

How do dogs get fleas?

Dogs get fleas from other dogs or the environment. As mentioned earlier, these tiny bloodsucking insects love to jump on dogs for the warmth too. You can trust that you will find them almost everywhere during the Australian summer. Plus, they’re capable of jumping near a foot in the air which makes it easy for them to move about as if they’re in their own colony.

How to prevent dog fleas?

There are several ways to deal with flea infestation and treatment that depend on what’s most practical for the dog owner and the state their dog is in. These include:

Oral flea treatments for dogs

Most of them will actually protect from more parasites than fleas. They prevent ticks, roundworms, hookworms and whipworms. They’re made with some chewy ingredients that only need to be ingested once a month. Manufacturers have made them tasty enough to be taken without the need to mix them with anything else.

Topical flea treatments for dogs

These treatments are applied directly on the dog’s body especially between the base of the neck or shoulder blades. They’re also known as “spot-ons” and they’re meant to spread all over your pet’s body and sweat glands which then produces a repelling smell to fleas and other parasites.

Flea collars for dogs

As the name suggests, these are collars with a concentrated chemical to repel and kill fleas and some ticks. Flea collars are especially useful if you notice your dog always scratching their face and areas around it. This essentially means that the rest of their body is left exposed and so you may need to use another treatment so as to keep them protected all over.

Powders, sprays and shampoos

Before oral treatments came into existence, these were very popular options for dealing with flea infestation. In order for them to be effective, they need to cover all the hidden parts of your dog’s body. Plus, one is supposed to avoid the dog’s eyes and mouth making them both inconvenient and toxic.

Customer review

By Alister on Pet Circle

“Scratching all the time annoys me as well, let alone being yelled at & getting kicked outside for getting fleas in their precious carpet (I won’t tell them about the couch or bedspread….). I hate the smell but the little buggers leave me alone after he puts it on me so I will tolerate it.”
