Buyer’s Guide
Trying to find the best flea shampoo for dogs can be a real challenge. There are so many factors for you to consider when it comes to finding the best product for your dog.
Is the product recommended by vets? Is it suitable for use on your dog? How long is the flea shampoo able to offer protection for?
We’ve put together this handy buyer’s guide to help you. As long as your chosen flea shampoo for dogs features the below factors, you can rest assured that you’ve found the ideal product for your pooch.
This is to help you make a fully informed decision and to save you from wasting money on a product that won’t be as effective as you need.
Let’s take a look at everything you need to know about flea shampoo below, or skip ahead to the frequently asked questions.
Length Of Protection
Of course, the most important thing that you will need to consider when choosing the best flea shampoo for your dog is how long the protection lasts.
You won’t want to opt for a flea shampoo that can only keep your dog protected for a few days at most. The longer the flea shampoo can keep your dog protected, the better.
This will ensure that you’re able to eliminate any flea infestations that can occur over time.
It’s worth noting that most of the fleas aren’t actually on your dog. They are actually around your home, in your soft furnishings.
So while a single application will kill off any fleas that are on your dog, it might not necessarily keep them protected from reinfestation if it only covers your dog for a couple of days.
So of course you should opt for the flea shampoo that can give your dog long lasting protection. You should also look to use this shampoo once a week to keep your dog protected from fleas.
It will also be worth remembering that a flea shampoo will only tackle part of the problem, and for truly long lasting results you will need to combine it with a spot on treatment from your vet.
Bottle Size
Another factor to consider is the size of the bottle you buy. The larger the bottle, the more value for your money you will get.
While some of the larger bottles may appear to be more expensive than others, when you work out how much you’re paying per ounce, you could actually be saving more money in the long run.
It will be worth considering how often you will be bathing your dog with this new flea shampoo. The more often you give your dog a bath, the more flea shampoo you will need.
It will be worth remembering that your dog will not need to be bathed more than once a week.
Effectiveness
The effectiveness of your chosen flea shampoo will be crucial. This will determine how well it’s able to kill fleas on contact and prevent your dog from reinfestation.
The vast majority of flea shampoos will be able to kill off the adult flea. However, some of the more effective products will also be able to kill off larvae and eggs.
It’s worth noting that because of the flea life cycle, their eggs will start to hatch long after you’ve killed off the adults that laid them.
It will also be worth considering whether the flea shampoo is able to protect your pet from other pests, too, such as ticks.
Dog Specific
While it is incredibly handy to opt for a versatile flea shampoo, you will need to ensure that it is suitable for use with dogs.
This may seem like an obvious point to mention, however, dogs have sensitive skin.
You will want to opt for a shampoo that is going to carefully balance the pH of your dog’s skin and not interfere with their delicate oils.
By opting for a dog specific flea shampoo, you can rest assured that it will be perfect for your pooch and won’t harm them.
It will also be worth opting for a veterinarian formulated product to give you added peace of mind.
Sensitive Skin
Dog’s notoriously have sensitive skin. So you will want to opt for a product that takes this into consideration. It will be best to opt for a product that uses natural ingredients instead of harsh chemicals.
While some of the harsher chemicals used in some products may very well give your dog long lasting protection, it could also be harmful to their skin, especially if they are bathed with these flea shampoos regularly.
Opting for a flea shampoo that uses only natural ingredients will give your dog the protection they need all while being kinder to their skin.
