Pros and cons of using Nexgard Spectra for dog flea treatment


Whether you have an indoor dog or an outdoor one, a tick or flea infestation can happen at any time; it can result in days of deep-cleaning in your home or frenzied trips to the vet. While you will find plenty of sprays, collars, solutions, and pills to choose from when it comes to year-round pest control, how do you know which one is the best choice for your dog?

One of the most popular oral medication is the NexGard Spectra, which is the European version of the US-based Nexgard. It is important that you choose the right type of medicine for your furry family member; the decision should never be considered light-heartedly, especially when it comes to pesticide-based tick and flea treatments.

In most cases, tick and flea infestation in dogs are caused by their comfortable fur coat and warm skin. Apart from ticks and fleas, Nexgard Spectra is also adept at treating different types of pests.
Fleas and ticks are parasites that can wait, for months at a time, to find a suitable host body to latch on and lay eggs; this cycle keeps then repeating.

Fleas and ticks are drawn to blood and warmth and are commonly seen during the summer/spring seasons. When your dog is having fun outside, especially in wooded areas, shrubs, and tall grass, there is a chance that ticks and fleas will attach themselves to your pet, and quite possibly to you as well.
