How to Choose the Most Effective Flea and Tick Treatment for Your Dog

Determining that your dog requires a flea and tick treatment is only half the battle. You must next traverse the assortment of collars, topical therapies, shampoos, and oral meds. Each has its own merits and downsides.

Consider your dog’s preferences, the degree of their infestation, and the time you have available for frequent flea treatments when making your ultimate decision.

This guide was created to assist you take the initial step by highlighting the differences between each therapy and its perks and downsides.

1. Considerations When Purchasing Flea and Tick Treatment for Your Dog

Before we discuss the various treatment options, there are a few more considerations that will help you make your ultimate decision.

Longevity

When selecting a flea treatment, the duration of use is one of the most crucial factors to consider. Some remedies only kill fleas on touch and must be used daily for optimal effects. This may interfere with your already packed agenda.

Other treatments are far more effective in preventing infestations. Although you must remember to make a note of when to repeat the treatment, they are less time-consuming for those who are seldom at home.

Waterproof

Dogs get wet. Even if they try everything to escape the hose and dreaded bath time, you’ll still find them wading through dirty ponds, splashing in puddles, and racing around in the rain.

Not all flea treatments are waterproof, and all of these wet activities might wash away the medication, leaving your dog vulnerable to fleas once more.

Supply

Several flea treatments, such topical ointments, come in a modest bulk quantity. Since they are intended to be used once every month, they are typically sold in boxes containing one to six or even eight items.

A larger supply may cost more initially, but you won’t have to purchase the same kind of medication every month.

However, if you discover that the therapy is not as effective as you had anticipated, a 6-month supply may go to waste if you do not use it.

Treatment vs Preventive Measures

On the surface, it may appear that therapy and prevention are the same thing. Although they are sometimes used to make treating your dog for fleas easier, their purposes are distinct.

The treatment is the first application. These treatments are meant to immediately kill fleas upon contact.

On the other hand, prevention consists of effects that are designed to be as long-lasting as feasible. These products enter into your dog’s skin or bloodstream and are slowly released until reapplication is necessary.

Flea shampoo, for instance, is officially a therapy. Although it can employ smells to repel or kill fleas for a little period after bathing, it is designed to kill fleas on contact after shampooing your dog.

Topical treatments are mostly preventative. As long as the chemicals are effective, it will continue to kill fleas.

Multi-pet Households

Numerous flea medicines designed for dogs are hazardous to other animals, such as your cat. As long as you keep dog-only therapies away from their feline counterparts, this is not a concern.

However, this is sometimes easier said than done, particularly if your pets like napping together.

Also problematic is treating both animals for fleas and ticks simultaneously. It is simple to go for the canine therapy instead of the feline one if you are pressed for time or a bit exhausted.

Keep your dogs’ flea medications and treatment days distinct for safety’s sake. This will allow you to focus on either your cats or your dogs without the chance of drug confusion.

2. What Kinds of Flea and Tick Treatment and Preventative Measures Are Available?

Now that you know what to consider when purchasing a flea and tick treatment for your dog, below are the available treatments and preventatives.

Finding the perfect one for your dog may take some time, but with a little work, you’ll soon have the optimal answer for your circumstance.

Collars

If you require a long-lasting preventative strategy, collars are your best bet. The chemicals on these adjustable, rubbery collars are meant to kill fleas and ticks for up to eight months, providing your dog wears one.

Collars can be especially handy during the hot summer months since they give continuous protection even when your exuberant dog dives into every body of water.

Typically, they fit inside your dog’s regular collar, so you don’t have to worry about compromising their street cred. Always remember to allow two fingers of space when placing a collar on your dog.

Relevant Solutions

Monthly treatments often include applying a solution equally down your dog’s spine. The chemicals are absorbed into your dog’s skin and stored in their oil glands to be gently released over the course of a month.

As long as you keep your dog away from water until it is dry, the majority of brands are waterproof and provide protection even if your dog swims.

Shampoos

If your dog likes baths, buying flea shampoos might make them more effective. In addition to often soothing sore skin, they are meant to kill fleas on touch. In addition, they frequently include more natural components than traditional chemical flea treatments.

The disadvantage of shampoos is that they must be used often. Many natural shampoos, in instance, must be reapplied approximately every week. This might help keep your dog smelling fresh, but it can also deplete healthy oils from their fur.

For optimal effects, shampoos should be used in conjunction with other flea treatments, such as collars or topical remedies.

Sprays

Although comparable to shampoos, flea sprays do not foam and do not require rinsing. You only need to grab the container and spray the product over your dog’s fur, taking care to avoid their eyes.

Some formulations can stain fabric, so it’s better to use them in areas that aren’t susceptible to stains.

Also, ensure that the spray is safe for your pet before applying it. A number of sprays are solely intended for use on carpets, furniture, and gardens.

Tablets for Chewing

Chewable pills can be used for daily therapy. They are intended to be a one-time treatment that kills fleas without the need to wait one or two days for a collar or topical medication to take effect.

FAQs

1. How often should you prevent fleas and ticks?

It is important to treat all your furry family members year-round with flea and tick control products. These can be prescription or over-the-counter, typically requiring application every 30 days.

2. Why is it important to prevent fleas and ticks?

3. Should dogs always be on flea and tick medicine?

Yes, dogs should be on flea and tick preventatives year-round to ensure their safety. Learn more about how fleas and ticks operate, the dangers they pose, and how to best protect your dogs and cats.
